Chapter 9 — Forbidden
The forbidden magic felt nothing like regular magic.
Regular magic had texture. Fire was warm and hungry, wind was light and restless, earth was slow and certain. Even holy magic had a quality to it — clean, bright, like sunlight through water. Every element Raj had ever used felt like something he was working with. A collaboration between intent and energy.
Forbidden magic felt like falling.
Not the panicked falling of losing your footing. The deliberate falling of stepping off a ledge you have already decided to step off. Gravity taking over from the point of no return. Pure and cold and completely without negotiation.
It came up through him from somewhere he hadn't known existed — deeper than his mana channels, deeper than the holy magic thread he had already burned through, deeper than anything the Summoner or Christine or any of the kingdom's tutors had ever mapped in their careful assessments of his all-type affinity. It rose like water filling a space that had always been there, waiting, patient, entirely indifferent to whether he was ready.
He was not ready.
He used it anyway.
The Demon King felt it before it manifested.
Raj saw it in the creature's expression — the first real change in those burning red eyes since the battle began. Not fear. Something adjacent to fear. Recognition. The Demon King had been alive for centuries and in those centuries it had apparently learned to identify the specific quality of someone reaching for something they were not supposed to have.
It moved toward him fast.
Rael stepped in its path. His shield arm was trembling and his mana was nearly gone and he planted himself in front of Raj with the absolute immovable certainty of someone who had decided this was where he stood regardless of arithmetic.
"Do it," Rael said. Not to the Demon King. To Raj.
Raj did it.
The forbidden magic came out of him in a form he had not directed and could not have predicted — not fire, not wind, not any element he knew. It was closer to light but heavier than light had any right to be. It moved like it had a specific destination already decided and the space between Raj and that destination was merely a formality to be crossed. It hit the Demon King's containment barrier — the dense layered mana shell that had absorbed everything Christine had thrown at it for the last hour — and did not break it.
It unmade it.
Not destroyed. Unmade. Like the barrier had never been a decision the Demon King had made, like the mana that formed it had simply forgotten what it was doing there. The shell dissolved from the inside out and the Demon King stood exposed for the first time since the battle began and its eyes went from recognition to something that might — in a creature that old and that vast — have been the distant cousin of alarm.
Raj was already moving.
His body did not feel like his body anymore. The forbidden magic was using his channels the way a flood uses a riverbed — the riverbed is involved in the process but is not making any decisions about it. He moved faster than he had ever moved, the magic pushing through his legs like it knew exactly how much force was needed and was simply applying it without asking. His sword was in his hand. He did not remember drawing it.
He crossed the hall in two seconds.
The Demon King swung at him — a strike that had leveled stone walls throughout the fight, that had driven Rael six meters across the floor — and Raj went under it. Not dodged. Under it, inside the arc, closer than sense permitted, close enough that the wind of the passing strike moved his hair.
His blade came up.
He had one chance at the angle he had mapped. The natural joint in the Demon King's armor — not a weakness exactly, more a place where the constructed darkness that served as protection had to allow movement, and movement meant a gap, and a gap for something big enough to move in meant a gap for a blade aimed correctly.
Christine had once said that Raj's instincts for angles were the best she had seen.
He aimed correctly.
The blade went in at the neck — clean, complete, the forbidden magic riding through the steel and into the strike and doing something to it that Raj could not describe and would not try to. The Demon King's body understood what had happened before the Demon King did. It went still with the specific quality of something that had just become a past tense.
Then it fell.
The hall was silent.
Raj stood in the silence and took inventory.
Mana — gone. Not low. Gone. Every reserve, every channel, scraped to absolute zero in a way that felt structural rather than temporary, like the channels themselves had been run through something too large for them and needed to remember how to be the right size again.
Holy magic — gone. The thin thread he had burned through in the early part of the fight and had not recovered.
Forbidden magic — also gone, but differently gone. The other absences felt like empty containers. The forbidden magic absence felt like a room that had been used for something and then sealed permanently. He would not be going back there.
Physical — three ribs, definitely. Left arm had taken something during the final approach he hadn't registered until now. The stone fragment from earlier had done more than he had assessed in the moment.
He turned around.
His party was still standing. Michal on his feet, one hand braced on his knee, bleeding but upright. Rael had not moved from the position he had planted himself in and showed no intention of moving now, as though standing here had been his entire plan and the plan was complete. Christine was lowering her hands from a containment configuration she had been maintaining throughout and her face had the grey quality of someone at absolute mana zero holding on through force of personality alone.
Lily was being helped up by Michal. She was conscious. She was looking at Raj.
Her mana had taken the hit from the wide area strike. Not catastrophic — Lily was SS rank and her reserves were deep even depleted — but the wound underneath the mana damage was real and she was favouring her left side and her face was pale in a way that sat in Raj's chest like a stone.
She had been healing him throughout the entire fight.
He had known that. He had always known that. But standing here now in the aftermath with the forbidden magic gone and everything else gone with it, the full weight of that settled differently. Every hit he had taken — every piece of contact he had pushed through and kept moving from — she had been quietly, continuously, without complaint or announcement, softening. Carrying part of the cost so he could keep going.
He had kept going. Right into the thing that had hurt her.
The stone in his chest got heavier.
"Raj," Michal said. His voice had the quality it got when he was managing his own response carefully. "Come here."
Raj took one step toward them.
His legs decided that was sufficient.
He went down slowly, which was almost dignified — not a collapse, more a careful acknowledgment of the situation, one knee then the other, the sword going down beside him with a sound that echoed once in the silent hall and then died. He put one hand on the floor and focused very hard on the specific task of remaining upright from the waist up.
"Lily—" he started.
"I am fine," she said immediately, pulling away from Michal and moving toward him. Her hands were already coming up with the healing light and he could see what it cost her to generate it right now, could see the effort behind the gold glow that she was making look effortless. "Raj, look at me."
He looked at her.
The healing came in warm and thorough and he felt the ribs realign with a sensation that was deeply unpleasant in a purely technical way and then the left arm and then the deeper channel damage from the forbidden magic, which made Lily's expression go very still and very focused for a long moment.
"That," she said quietly, working through it, "is not something I have seen before."
"Forbidden magic," he said. His voice came out smaller than he intended. "Channel damage."
"I can see that." She did not stop working. "I have it. Hold still."
He held still. Around them Michal was checking Rael's shield arm and Christine had sat down on the floor with her spell index in her lap and was staring at it without reading it, which was her version of needing a moment. The Demon King's body had already begun to dissolve — slowly, the darkness that had comprised it unraveling at the edges like old cloth.
It was over.
It was actually over.
Raj looked at the dissolving remains of the thing they had spent a year preparing to kill and felt — not triumph. Something quieter. The particular stillness of a breath held for a very long time being finally released.
Then the forbidden magic's other cost arrived.
It did not announce itself. It did not build dramatically. It came the way certain things came — with the simple completeness of something that had always been scheduled and was now simply on time. His remaining mana channels — the ones Lily had just carefully repaired — went quiet. Not damaged. Not empty. Quiet, in the way that things went quiet when they were finished.
He understood immediately what was happening.
The forbidden magic's cost was not the mana he had spent using it. That was just fuel. The cost was the life force underneath the mana — the vital energy that the mana channels ran through, that kept the whole system alive and functioning. It was withdrawing. Calmly and completely and without any particular interest in his opinion on the matter.
He looked at Lily's hands still working on him and thought — she is going to notice in about ten seconds and I need to say something before that.
"Lily," he said.
She looked up. Her eyes went to his face and whatever she saw there made her hands still.
"The channel damage," he said carefully. "The deeper part."
"Raj—"
"You can't fix that part." He kept his voice steady. He had known this was a possibility when he opened that locked room. He had made the calculation. He stood by the calculation. "It's not damage. It's the cost. It's different."
Her expression did something he had never seen it do before. Something that broke through every layer of warmth and composure she maintained like it wasn't even there.
"No," she said.
"Lily."
"No." Her hands came back up, the gold light intensifying, pushing harder, and he could see her burning through reserves she did not have, throwing everything at something that was not responding because it was not damage and damage was the only thing healing could address. "No, I have you. I have you, just — hold on—"
"Lily." He reached up and put his hand over hers. The gold light flickered. "You have done enough. You have done more than enough. You have been doing enough since the moment we arrived in that throne room." He paused. "You were healing me the whole time. I know. I noticed. I always noticed."
She was crying. He had never seen Lily cry before and it turned out it looked exactly like he might have imagined — quiet, contained, completely at odds with the fact that it was happening at all.
"You are not the weakest," she said. Her voice was barely above a whisper. "You never were. You were never—"
"I know," he said. And in that moment — looking at the dissolved remains of the Demon King, feeling the forbidden magic's cost running its course with complete indifference, his party alive and standing around him — he actually did know. Not argued into it, not reasoned toward it. Just — knew, in the simple way you knew things that had always been true.
He lay back on the cold stone floor of the Demon King's throne room and looked at the ceiling.
Michal was there. He crouched beside Raj and said nothing, which was the most Michal thing he could have done. Just — present. Solid. There.
Rael sat down heavily nearby, which was as close to a vigil as Rael did.
Christine closed her spell index and sat down facing him, and did not look away.
Lily held his hand and did not let go.
The hall was quiet and the darkness was dissolving and somewhere outside the dead valley the world was presumably continuing, entirely unaware that five people from five different dimensions had just done the thing they were brought here to do.
Raj thought about his mother. About the trash he never took out.
He thought about a year of early mornings and training grounds and bad food and good tea and four people who had somehow become the loudest thing in a life that had always been very quiet.
He smiled.
It was a good smile. He was aware of that. The kind that came from somewhere real and didn't need an audience and didn't need to be explained.
The ceiling was very high and very dark and very peaceful.
He closed his eyes.
