**Oa, Training Complex Alpha**
Harry Potter stood before a floor-length mirror in his quarters and barely recognized himself.
Three months of Kilowog's brutal training regimen had transformed his body completely. The thin, underfed boy who'd arrived on Oa was gone. In his place stood someone who looked like he'd been carved from marble—broad shoulders, defined chest, arms that showed real muscle definition. Not bodybuilder huge, but lean and powerful, like a gymnast or a martial artist.
The Starheart had accelerated everything. Tomar-Re's supplements had provided the raw materials, but it was the ring that had truly changed him. His bones were denser now, his muscle fibers more efficient. His metabolism had been optimized. Even his eyesight was sharper—he could see details at distances that should have been impossible for human vision.
*You are no longer entirely human,* the Starheart had told him last week. *Your body has been enhanced at the cellular level. You're stronger, faster, more resilient than baseline human physiology allows. You are becoming what you need to be.*
And now, on the eve of his final test, the Starheart had manifested something unprecedented.
Armor.
It had materialized around him during this morning's meditation session—not conjured, not created. *Manifested*, as though it had always been there, waiting. The Starheart had explained it as "a representation of your will made into permanent reality."
Harry studied his reflection, still adjusting to the sight.
The armor was magnificent.
The chest piece was smooth and contoured, molded to his new muscular physique like a second skin. Emerald green, polished to a mirror shine, with the Green Lantern symbol blazing at its center—bright enough to cast shadows in the room. The emblem pulsed with his heartbeat, a living power core that drew the eye.
Below the chest, segmented armor plates covered his abdomen, flexible enough to move with him but strong enough to turn aside blows that would shatter bone. The design was both practical and beautiful—form following function, but with an aesthetic that spoke to something primal. This wasn't just protection. This was a *statement*.
The pauldrons rose from his shoulders like the wings of a raptor—large, curved, edged in silver that caught the light. They added inches to his already broad shoulders, making him look imposing in a way that skinny Harry Potter had never managed.
His arms were covered in what looked like dragon scales—black and flexible where they needed to bend, transitioning to solid green plating at the forearms. Heavy bracers protected his wrists, etched with symbols that Harry didn't recognize but somehow understood. They were words of power, concepts made manifest: *Courage. Sacrifice. Will.*
The leg armor was sleeker, designed for movement. Green plates over a darker undersuit, with silver reinforcement at the joints. The boots were solid, practical, but somehow still elegant—designed for someone who might need to sprint or fly at a moment's notice.
And the cape.
Harry turned, watching how it moved. Dark green, nearly black in the shadows, flowing from his shoulders like liquid night. It attached via two circular metallic nodes at his collarbone—polished silver, etched with the same symbols as his bracers. The collar was raised and armored, framing his face, adding a sense of regality.
He looked like something out of legend. A knight-errant crossed with a superhero, magical warrior meets cosmic protector.
He looked *powerful*.
*This is who you are becoming,* the Starheart said quietly. *Not just Harry Potter. Not just the Boy Who Lived. Something more. Something that bridges worlds.*
A knock at his door interrupted his contemplation.
"Poozer! You decent in there?"
Harry smiled. "Come in, Kilowog."
The massive Bolovaxian entered, ducking through the doorway—followed by Tomar-Re and, surprisingly, Hal Jordan.
"Hal!" Harry said, surprised and pleased. "When did you get back?"
"About an hour ago," Hal said, grinning. "Couldn't miss your final test. Or the oath-taking afterward." His grin faltered slightly as he took in Harry's appearance. "Holy... Harry, you look—"
"Different," Tomar-Re supplied. "The transformation is remarkable. Your muscle mass has increased by approximately forty percent. Bone density is up sixty-three percent. And your cardiovascular efficiency—" He caught Harry's expression and coughed. "Apologies. I'm doing the academic analysis thing again."
"You look good, poozer," Kilowog said, and there was genuine pride in his voice. "Three months ago, you could barely do fifty push-ups. Yesterday, I saw you do two thousand without breaking a sweat."
"The Starheart helped," Harry said automatically.
"The Starheart gave you the tools," Kilowog corrected. "You did the work. Don't diminish that." He circled Harry, examining the armor. "This is new. Since when can you manifest permanent constructs?"
"Since this morning," Harry admitted. "The Starheart said my will had reached the point where it could make something permanent. That the armor was a representation of my resolved will—my determination to protect people, to be strong enough to stand between them and danger."
"It's impressive," Tomar-Re said, scanning the armor with his ring. "The energy signature is... unusual. It's reading as both construct and actual physical matter. As though you've convinced reality itself that the armor is *real*, not just solidified light."
"That's the Starheart's specialty," Hal said. "Alan Scott could do similar things—create objects that persisted even when he wasn't consciously maintaining them. But Harry, you're going to need one more thing before the final test."
"What's that?"
"A mask," Hal said. "Or helmet. Something to protect your identity. Most Green Lanterns use a domino mask—" He demonstrated with his own ring, a simple green mask appearing across his eyes. "—but given your armor's aesthetic, you might want something more substantial."
Harry frowned. "I don't really like masks. At Hogwarts, during the war, the Death Eaters wore masks. It made them feel... faceless. Anonymous. I don't want to hide who I am."
"It's not about hiding," Tomar-Re said gently. "It's about protecting the people you care about. Harry, you're about to become a publicly known Green Lantern. That means enemies might try to hurt you by hurting your friends. A mask—or helmet—creates separation between Harry Potter the person and Green Lantern 2814.2 the cosmic protector."
"Plus," Kilowog added, "it looks intimidating. And intimidation is half the battle sometimes. If you can make bad guys surrender by looking scary enough, that's a win."
Harry considered this. They had a point. And if he was going to wear armor that made him look like a fantasy knight crossed with a superhero, a helmet might complete the aesthetic.
"All right," he said. "But not a mask. Something more... substantial."
He closed his eyes, reaching for the Starheart. *Show me,* he thought. *Show me what I should look like. Complete.*
The Starheart responded with enthusiasm.
Power flowed through Harry, and he felt the armor shift, grow, *complete* itself. New weight settled on his head and shoulders—not heavy, perfectly balanced, but *present*.
When he opened his eyes and looked in the mirror, his breath caught.
The helmet was magnificent.
It was a full-face enclosure—smooth, seamless, no visible seams or openings except for the eyes. The faceplate was opaque emerald green, polished to a mirror shine, completely concealing his features. He looked mysterious, imposing, *faceless* in a way that was somehow more powerful than any expression could be.
The jawline tapered to a sharp V-shape, emphasizing sleekness. But what really caught the eye were the horn-like extensions rising from the forehead—tall, curved, shaped like stylized antlers or arcane blades. They swept back and up, giving him a crowned silhouette that spoke of royalty and power.
The entire helmet was lustrous metallic emerald, covered in fine swirling engravings—silver patterns that looked Celtic or perhaps elven, intricate and beautiful. The engravings covered the horns, the brow, the cheekplates, and they *glowed*, pulsing softly with inner light.
The eyes were narrow slits that burned with bright neon green fire. They gave the helmet a watchful, intimidating presence—calm yet powerful, patient yet dangerous.
"Merlin," Harry breathed. His voice came out slightly modulated, deeper, resonating in a way that his normal voice didn't. The helmet was enhancing it, making him sound more authoritative.
"Well," Hal said after a long moment. "That's certainly not a standard Green Lantern look."
"It's remarkable," Tomar-Re said, circling Harry to examine the helmet from all angles. "The craftsmanship is extraordinary. And it's all construct? Maintained by the Starheart?"
"Maintained by my will," Harry corrected. "The Startheart says this armor—helmet included—is permanent now. As long as I have the will to be a protector, it will exist."
"Meaning you could take it off?" Kilowog asked.
Harry concentrated, and the helmet dissolved into motes of green light. His face was visible again—though his features had changed too, he noticed. Stronger jaw. More defined cheekbones. Three months of proper nutrition and cosmic enhancement had done their work.
He willed the helmet back, and it materialized seamlessly, clicking into place with a sense of *rightness*.
"Convenient," Hal said. "Most Lanterns would kill for armor that good. And Harry—" He paused, studying the complete ensemble. "—you don't look like a Green Lantern anymore. You look like something else entirely."
"What do I look like?" Harry asked, genuinely curious.
Hal smiled. "You look like an Emerald Knight."
The name resonated. Not Green Lantern—though he wore the symbol, though he wielded the power. But something older. Something that bridged the gap between magic and science, between Earth's legends and the cosmos' reality.
*Emerald Knight,* Harry thought, testing how it felt. *I like that.*
"It fits," Kilowog said. "Traditional Green Lantern protocol probably won't apply to you anyway, poozer. You're too much of a special case. Might as well have a title that reflects that."
"The Guardians won't like it," Tomar-Re warned. "They prefer uniformity. Standardization."
"The Guardians can deal with it," Hal said firmly. "Harry's got the Starheart. That makes him essentially independent. They can suggest, but they can't command." He looked at Harry. "But you still have to pass the final test. You still have to take the oath. You ready for that?"
Harry looked at himself in the mirror one more time. The armored knight staring back at him was confident, powerful, ready. Everything the Boy Who Lived had needed to be but never had the strength for.
Now he had the strength.
Now he was ready.
"I'm ready," Harry said, and his modulated voice made it sound like a vow.
"Good," Kilowog said. "Because your final test starts in two hours. And poozer? It's gonna make everything we've done so far look like a warm-up."
---
**Oa, Final Testing Arena - Two Hours Later**
The arena was different from the training complexes Harry had grown accustomed to. This one was *massive*—easily ten miles across, with a ceiling so high it disappeared into artificial clouds. The floor was segmented into different terrain types: urban environments, asteroid fields, dense forests, oceanic platforms, and what looked like the surface of an active volcano.
And waiting in the center, floating above a circular platform, were the Guardians of the Universe.
All twelve of them.
Harry descended slowly, his cape billowing behind him, Hal flanking him on one side. Kilowog and Tomar-Re took positions at the arena's edge—instructors, but not participants. This test was Harry's alone.
"Harry Potter," Ganthet said, his voice amplified to fill the arena. "You have trained for three months. You have learned construct theory, combat tactics, flight dynamics, and cosmic law. You have demonstrated exceptional aptitude and remarkable creativity. But knowledge is not wisdom. Skill is not character. And power without purpose is merely destruction."
"Today," Sayd continued, "you face the final test. Not a test of strength—we know you're strong. Not a test of will—the Starheart chose you, proof enough of that. This is a test of *judgment*. Of whether you can make the hard choices that Green Lanterns face every day."
"You will be presented with scenarios," Appa Ali Apsa said, his tone stern. "Some will have clear solutions. Others will not. Some will require violence. Others will require restraint. You will be judged not on whether you succeed—but on *how* you choose to succeed."
"Or how you choose to fail," another Guardian added. "Sometimes the right choice is failure by certain metrics."
Harry felt the weight of their attention—twelve ancient beings who had seen civilizations rise and fall, who had created the Green Lantern Corps to impose order on chaos. They weren't trying to intimidate him. This was just who they were.
"I understand," Harry said, his voice resonating through the helmet. "What's the first scenario?"
The arena shifted.
---
**Scenario One: The Hostage**
The urban environment activated—suddenly Harry was standing in what looked like a major city. Skyscrapers rose around him, streets filled with constructs that resembled civilians. And on top of the tallest building, a figure held a hostage.
Harry flew up immediately, the Starheart propelling him with ease.
The hostage-taker was an alien—reptilian, seven feet tall, holding what was clearly a powerful explosive device in one hand. His other hand clutched a civilian—a small alien child, barely three feet tall, trembling with fear.
"Stop!" the reptilian snarled when Harry landed on the rooftop. "Come closer and I detonate! The explosive will level six city blocks!"
Harry's mind raced. Standard hostage situation—except cosmic-level stakes. Six city blocks meant thousands dead. But the child was right there, terrified, whimpering.
*What would Hermione say?* Harry thought. *Analyze the situation. Look for options I'm not seeing.*
He studied the explosive—his ring feeding him data. Fusion-based, highly unstable, yield approximately five kilotons. Definitely enough to level six blocks. Possibly more.
The hostage-taker's emotional state: desperate, cornered, but not suicidal. He *wanted* to escape. The bomb was leverage, not a death wish.
"What do you want?" Harry asked, keeping his voice calm despite the modulation.
"Safe passage," the reptilian hissed. "Off this planet. Off this sector. I want amnesty, protection, and—"
"Not happening," Harry interrupted. "What you're holding is illegal in seventy-three sectors. You're a war criminal. I can't give you amnesty."
"Then the child dies! The city dies!"
Harry's mind worked faster. The child was three feet from the explosive. If he tried to snatch the child with a construct, the hostage-taker would detonate. If he attacked the alien, same result. And flying away meant abandoning the civilian to die.
But—
*The Starheart doesn't just make constructs,* Harry thought. *It makes impossible things real.*
"Okay," Harry said, raising his hands. "Okay. You win. I'll arrange transport. Just... put down the bomb. Show good faith."
The reptilian's eyes narrowed. "You think I'm stupid? The moment I—"
Harry wasn't listening anymore. He was *concentrating*.
The Starheart flared, and Harry did something he'd been practicing with Tomar-Re for weeks: he created a construct inside another object.
A tiny shield, smaller than a marble, materialized inside the explosive device's core. Not blocking anything. Just *there*. And then Harry expanded it.
The explosive shattered from the inside—components separating, fusion material scattering harmlessly, detonation mechanism destroyed. All in the span of a heartbeat.
The reptilian stared at his now-useless device in shock.
Harry created a cage construct around the hostage-taker, grabbed the child with a gentle telekinetic field, and had both secured before the alien could process what happened.
"Scenario complete," Ganthet's voice announced. "Creative solution. Non-lethal. Child unharmed. City saved." A pause. "But Harry Potter—what if the explosive had been shielded against internal construct insertion? What if your creative solution hadn't worked?"
"Then I'd have tried something else," Harry said, settling the child-construct on the ground. "Created a portal to shunt the explosion into space. Or a massive shield to contain the blast. Or—" He thought about it. "—honestly, I'd have been willing to take the explosion myself if it meant the child lived."
"You would sacrifice yourself?" Sayd asked.
"If it was the only option? Yes." Harry's voice was steady. "I've done it before. I'll do it again if I have to. That's what this ring means, isn't it? Protecting others, even at cost to myself?"
The Guardians exchanged looks.
"Proceed to scenario two," Appa Ali Apsa said.
---
**Scenario Two: The Trolley Problem**
The arena shifted again. Harry found himself on what looked like a train track—except cosmic-scale. Two paths diverged ahead. On one path, five alien civilians were bound to the track. On the other path, one civilian.
And bearing down on the junction was a massive construct train, moving at speeds that made stopping impossible.
Harry's ring immediately supplied the parameters: *The train cannot be stopped. Its momentum is maintained by external power sources beyond your control. You can switch the track, but you cannot prevent impact. Choose.*
Five lives or one life.
The trolley problem, given cosmic stakes.
Harry stared at the scenario, his mind racing. This was a test of moral philosophy as much as power. What would he choose? The utilitarian answer—save five, sacrifice one. The deontological answer—refuse to participate in a system that forced such choices.
But this was the Corps. This was reality. Sometimes there were no good choices.
*What would Dumbledore say?* Harry thought. *What would Sirius say? What would—*
He stopped. No. This wasn't about what they would say. This was about what *he* believed.
"No," Harry said aloud.
"No?" Ganthet repeated. "Harry Potter, you must make a choice. The train is approaching—"
"I refuse the premise," Harry said firmly. He raised his hand, Starheart blazing. "You said the train can't be stopped by me. You didn't say it can't be stopped at all."
He created a construct—not a shield, not a portal. A *second train*, heading toward the first on a collision course.
The two trains met with a thunderous crash—construct meeting construct, external power source meeting internal will. They shattered each other, momentum canceling out in a shower of green light.
The civilians were unharmed. All six of them.
Silence filled the arena.
Then Kilowog's booming laugh echoed from the sidelines. "That's my poozer! Didn't even *consider* the binary choice!"
"You changed the parameters of the scenario," Appa Ali Apsa said, and he didn't sound pleased. "That's not how the test—"
"The test said the train couldn't be stopped by me," Harry interrupted. "It didn't say I couldn't create something else to stop it. I changed the situation to one where I didn't have to sacrifice anyone." He looked directly at the Guardians. "Isn't that what Green Lanterns are supposed to do? Find creative solutions? Refuse to accept that innocent people have to die?"
"Sometimes," Sayd said quietly, "innocent people *do* have to die. Sometimes the mathematics of a situation allow for no perfect solution. What will you do then, Harry Potter? When the choice truly is five lives or one, and there is no third option?"
Harry was silent for a long moment. "Then I'd choose the five," he said finally. "And I'd spend the rest of my life figuring out how to prevent that situation from happening again. But I won't accept that a scenario is impossible to change until I've tried everything I can think of."
"Stubbornness," Appa Ali Apsa said.
"Determination," Ganthet corrected. "Proceed to scenario three."
---
**Scenario Three: The War**
The arena transformed into a battlefield.
Two armies faced each other—constructs, but detailed enough to seem real. On one side, what looked like a human-ish species in silver armor. On the other, reptilian aliens in crimson battle gear. Both sides were armed. Both sides looked ready to kill.
Harry floated between them, suddenly very aware that he was one person standing between two armies.
"Scenario parameters," his ring supplied. "Both sides have legitimate grievances. Both sides have committed atrocities. Both sides believe their cause is just. Diplomacy has failed. They will fight in thirty seconds unless you intervene. Choose: aid one side, aid both sides, or aid neither."
Harry's heart sank. This wasn't a scenario with a clever solution. This was the nightmare situation every Green Lantern faced: war between civilizations, where both sides had valid points and both sides had blood on their hands.
*What would Hermione do?* Harry thought frantically. *She'd look for root causes, for—*
Twenty seconds.
Harry reached out with his ring, scanning both armies for emotional states. Fear. Anger. Grief. Loss. Both sides had lost people. Both sides wanted vengeance. Both sides thought they were the righteous ones.
Fifteen seconds.
"STOP!" Harry's voice boomed across the battlefield, amplified by his helmet. Both armies paused, looking at him.
Ten seconds.
"I am Green Lantern 2814.2," Harry said, and he put every ounce of authority he could muster into his voice. "I am authorized by the Guardians of the Universe to maintain peace in this sector. And I am telling you both—*stand down*."
"We have the right to defend ourselves!" the silver-armored leader shouted.
"They attacked our colony!" the reptilian commander countered. "We have the right to retaliation!"
Five seconds.
Harry made a choice.
The Starheart flared, and suddenly both armies were enclosed in separate containment fields—massive domes of green light, impenetrable, sound-proofed. They could see each other, but they couldn't fight.
"Scenario failed," Appa Ali Apsa said immediately. "You have prevented the battle through force, not through resolution. The underlying conflict remains. What happens when you release them?"
"I don't know," Harry admitted. "But they're not killing each other *right now*, which gives me time to figure it out."
"Time is finite," Appa Ali Apsa pressed. "You cannot maintain those containment fields forever. Eventually, your will will falter. Your power will run out. And when it does, they will fight. You have only delayed the inevitable."
Harry looked at the two armies—both pounding against the barriers, shouting silently, furious at being contained.
"Then I use that time to find the real problem," Harry said. "To understand why they're fighting. To address root causes instead of symptoms. And if that takes days or weeks or months—" He met Appa Ali Apsa's gaze steadily. "—then I spend days or weeks or months. Because the alternative is letting them kill each other, and I won't accept that if there's any other option."
"Even if your intervention prolongs the conflict?" Sayd asked. "Even if by preventing this battle, you ensure the war continues for years? Sometimes, Harry Potter, the kindest thing is to let wars reach their natural conclusion. Painful, but finite."
"No," Harry said firmly. "No, I don't accept that. War doesn't have to be inevitable. Hatred doesn't have to be permanent. If I have the power to stop people from killing each other, then I use that power. And then I work to solve the actual problem."
"Idealism," Appa Ali Apsa said dismissively.
"Hope," Harry countered. "And will. Isn't that what Green Lanterns are supposed to embody?"
Ganthet raised a hand. "Scenario complete. Proceed to final scenario."
---
**Scenario Four: The Impossible Choice**
The arena went dark.
Then light bloomed—but not from Harry's ring. From a construct in front of him.
Two faces. Both people Harry knew.
Ron Weasley on the left. Hermione Granger on the right.
Both were suspended in separate containment fields. Both looked terrified. And above them, a timer counted down from sixty seconds.
"Final scenario," Ganthet's voice said, and there was something heavy in it. "You can save one. Only one. The other will die. Choose."
Harry's heart stopped.
"This isn't—they're constructs," he said, but his voice shook. "This isn't real."
"The scenario is real," Appa Ali Apsa said. "This situation or something like it will eventually confront you. Power allows you to save many people—but not all people. Sometimes you must choose who lives and who dies. So choose, Harry Potter. Your best friend, or the woman who loves him?"
Fifty seconds.
Harry stared at the construct faces. They were *perfect*. Every detail exact. Ron's freckles. Hermione's bushy hair. The expressions of trust mixed with terror—believing Harry would save them, but not knowing how.
Forty seconds.
"I can't," Harry said. "I can't choose between them."
"You must," Sayd said, not unkindly. "That is the burden of power, Harry. You must make impossible choices. What matters is that you make them. Choose."
Thirty seconds.
Harry's mind raced. Creative solutions. Change the parameters. There had to be a way—
But he'd tried that in the other scenarios. And the Guardians had learned. This time, they'd made it truly binary. Save one. Lose one. No third option.
Twenty seconds.
*The Starheart,* Harry thought desperately. *Can you—*
*I cannot save both,* the Starheart said, and there was genuine regret in its ancient voice. *I am powerful, but the scenario parameters are absolute. You must choose, Harry Potter. This is the nature of power. Sometimes there are no good options.*
Ten seconds.
Harry looked at Ron. At Hermione. At two people who had stood by him through everything. Who had risked their lives for him countless times. Who were *family* in every way that mattered.
How could he choose? How could anyone choose?
Five seconds.
"I choose both," Harry said.
"That is not an option—" Appa Ali Apsa started.
"I CHOOSE BOTH!" Harry's voice was a roar, power flooding through him, the Starheart blazing like a star. "I refuse to accept that I have to sacrifice either of them! I refuse to accept that power means choosing who deserves to die!"
The timer hit zero.
Harry *moved*.
Not physically—with his *will*. He reached out with every ounce of power he possessed, with every bit of stubborn determination that had kept him alive through seven years of Hell, with every piece of love he felt for his friends—
And he *grabbed* time itself.
The Starheart responded to his impossible demand by doing something impossible. The timer froze. The scenario locked. For just a heartbeat—less than a heartbeat, a fraction of a second—Harry existed outside the normal flow of cause and effect.
And in that frozen moment, he created two constructs simultaneously. One around Ron. One around Hermione. Both pulling them from the containment fields, both wrapping them in protection, both saving them—
The moment broke.
Time resumed.
Both constructs were in his hands, both friends safe, the timer expired but *meaningless* because Harry had refused to let it matter.
The arena was silent.
Then Ganthet spoke, and his voice was soft with something that might have been awe: "You stopped time."
"For a fraction of a second," Harry said, breathing hard. The effort had nearly drained him, even with the Starheart. "Just long enough. Just barely enough."
"That should not be possible," Appa Ali Apsa said, but he didn't sound angry. He sounded... *impressed*. "The Emotional Spectrum does not interact with temporal mechanics. Time is universal, constant, immutable—"
"Not when will meets magic," Tomar-Re said from the sidelines, his voice awed. "The Starheart operates on principles we don't fully understand. It seems Harry's will—his absolute refusal to accept the binary choice—was strong enough to bend reality itself. For just a moment."
"Can you do it again?" Sayd asked.
Harry shook his head. "No. Maybe never again. That nearly killed me. The Starheart says I burned through more power in that instant than I've used in three months of training."
"But you did it," Ganthet said. "When faced with an impossible choice, you created a third option by force of will alone. You changed the parameters of reality itself rather than accept that your friends had to die."
"Because they're my friends," Harry said simply. "Because I love them. Because I've already lost too many people, and I refuse to lose more if there's any way—*any way at all*—to prevent it."
He looked at the Guardians, at these ancient beings who had seen everything, who believed in order and rules and the mathematics of sacrifice.
"I know power requires choices," Harry said. "I know sometimes people die despite our best efforts. I know the universe is vast and terrible and full of things I can't control. But when I *can* control something? When I have the power to save someone? Then I use that power. Every time. No matter the cost to myself."
"Even if it means burning out your ring?" Appa Ali Apsa challenged. "Even if it means dying yourself?"
"Yes," Harry said without hesitation. "Because that's what the Starheart chose me for. Not to be the most powerful. Not to be the most skilled. But to be someone who *refuses to quit* when people need saving. Someone stubborn enough to attempt the impossible because the alternative is unacceptable."
The Guardians were silent for a long, long moment.
Then Ganthet descended, floating until he was level with Harry. The ancient being studied him with eyes that had witnessed the birth of stars.
"Harry Potter," Ganthet said finally, "you have completed your final test."
"Did I pass?" Harry asked.
"You did not follow protocol," Appa Ali Apsa said.
"You changed the parameters of every scenario," another Guardian added.
"You refused to accept limitation," a third said.
"You attempted the impossible," Sayd continued.
"And succeeded," Ganthet finished. "Harry Potter, you have demonstrated judgment, creativity, compassion, and will beyond what we expected from a trainee with only three months of experience. You have proven that the Starheart chose wisely."
The Guardians rose as one, forming a circle around Harry.
"We ask you now," Ganthet said formally, "to speak the oath. To join the Green Lantern Corps as a full member. To pledge your will to the protection of all sentient life in Sector 2814 and beyond. Will you take this oath, Harry Potter?"
Harry looked at them. At these beings who had created order from chaos. At Hal Jordan, grinning proudly. At Kilowog and Tomar-Re, his instructors, who had pushed him harder than he'd ever been pushed.
He thought about Earth. About his friends. About all the people who had died so he could stand here.
He thought about what the Starheart meant. What this oath meant.
And he knew his answer.
"I will," Harry said.
"Then raise your ring," Ganthet said. "And speak the words."
Harry raised his right hand, the Starheart blazing.
And he spoke:
"*In brightest day, in blackest night,*
*No evil shall escape my sight.*
*Let those who worship evil's might,*
*Beware my power—Green Lantern's light!*"
The Starheart pulsed, and suddenly Harry wasn't just speaking. He was *feeling* the words. Understanding them. The oath wasn't just a pledge—it was a *binding*, a contract between him and the universe itself.
He was promising to stand against evil. To protect the innocent. To be a light in the darkness. And the universe was *listening*, was accepting his vow, was granting him the authority to fulfill it.
Green light exploded from the Starheart, washing over the arena. Every Guardian, every Lantern present, every construct—all of them glowed with reflected power. The light grew brighter, brighter, until Harry could see nothing but green—
And then it faded.
Harry stood in the center of the arena, his armor gleaming, his helmet magnificent, his cape flowing. The Starheart burned on his finger with steady, eternal light.
"Welcome to the Green Lantern Corps," Ganthet said. "Green Lantern 2814.2. Harry Potter of Earth."
A pause.
"The Emerald Knight."
The name resonated. Not just in the arena—in reality itself. Harry felt it settle around him like the armor, like the oath, like his new identity.
He wasn't just Harry Potter anymore.
He wasn't just the Boy Who Lived.
He was a Green Lantern. A protector of sectors. A warrior of will.
An Emerald Knight.
And the universe, vast and patient and full of challenges he couldn't yet imagine, waited for him to begin.
