In the Hall of Kings, no one spoke after Eren repeated the words.
Atum's fists had closed tight.
Aru sat still as carved wood, but his eyes had sharpened.
"Now choose correctly," Eren said again.
Quieter this time.
"That was how he thought. That was how all of them thought at their highest. Not kill or spare. Not advance or retreat. Break the soul first. Make it betray one duty to save another."
He turned toward the dark arches where Nam Lapi moved under moonlight.
"And if you waited too long, they chose for you."
Then he went back to the terrace.
The seal was breaking in two directions at once.
Blue-white force still rose from the buried defense in surges, making the old carvings blaze like veins of light.
Red-black corruption spread from Vorun Kael's blade where it sat in the seal-rim, running through the script in branching cracks like poison in water.
The defenders nearest the center had dropped to one knee.
Some were half locked by paralysis.
One still tried to raise his sword.
Another could only drag himself by his fingertips through blood and powdered stone.
The Messenger captain who had held the ring shook so hard his teeth knocked together.
Beside the seal, the woman from Guoga stood with one hand over her ruined chest and the other pressed flat to the blazing stone.
Silver light shuddered through her body.
It was not enough.
Young Eren saw that in one glance.
If he attacked Vorun first, the corruption would deepen.
If he went for the seal first, Vorun would kill him before he cleared it.
If he moved to protect the woman, the center ring would become a grave for all three of them.
There was no clean choice.
Only the least fatal one.
He ran anyway.
Vorun did not move to meet him.
That made it worse.
He just watched Eren come over the broken terrace, black fire still leaking in thin lines from the wounds the human blade had left in him.
"Look at you," Vorun said. "Still trying to save everything."
Eren did not answer.
He cut straight for Vorun's weapon arm.
Vorun blocked it easily. Sparks burst. The impact ran through Eren's spine, but this time he did not give ground. He drove in harder, shoulder low, trying to force the angle away from the center of the seal.
Vorun's mouth shifted.
"You learn."
Eren snarled, "I improve around annoyance."
Behind him, the woman shouted without opening her eyes.
"The blade is anchoring the corruption. Pull him off it or the seal takes his pattern."
Eren barked back, "That would have helped sooner."
"It helps now!"
Vorun twisted.
Small movement.
Almost lazy.
It nearly took Eren's hand off.
The black edge flashed across his knuckles close enough for the cold of it to bite the skin without touching. Vorun stepped into the opening and drove a crushing blow toward Eren's ribs.
Eren caught it too late.
The strike hit his sword, tore through his guard, and smashed him sideways into a cracked obelisk. Stone split. Pain burst along his wounded side so hard the whole battlefield turned white for one blink.
A voice from the ground shouted, "Commander!"
The half-paralyzed captain was forcing himself up inch by inch, blood on his teeth.
Eren shoved off the obelisk and got one boot under him.
"Stay down if you want to live!"
The captain almost laughed. "You first!"
Vorun pulled his blade free of the seal-rim just long enough to slash at Eren's throat.
That changed the fight.
The red-black corruption in the carvings faltered for half a breath where the blade lost contact.
The woman felt it at once.
"Again!" she cried. "Pull him off it again!"
Eren's eyes snapped to the glowing fracture lines.
There.
Not a weakness in Vorun.
A weakness in what Vorun was doing.
Vorun saw Eren understand.
Then he came hard.
No patience now.
No testing.
The First Blade attacked to kill.
He moved in a storm of black edges and hardening shell, every strike clean, every angle cruel, every change of line made just to overload thought before flesh. The weapon changed shape in motion—cut becoming thrust, thrust becoming hook, hook becoming paralytic contact meant to seize the body for the finishing blow.
Eren stopped trying to beat him straight.
He fought for inches.
A deflection instead of a block.
A slip instead of a brace.
One low turn that let the blade shave armor instead of split bone.
He stopped aiming at flesh and started aiming at direction—keeping Vorun's strikes moving away from the places where the seal could be struck cleanly.
The woman heard it in the rhythm before she saw it.
"Good!" she shouted, voice shaking under strain. "Don't meet his force. Ruin his shape."
Vorun's head turned a fraction.
"Still teaching primitives."
She answered through clenched teeth, "Still dying from them."
One of the half-paralyzed guards roared and threw himself from the ground at Vorun's back.
It was hopeless.
It still mattered.
Vorun turned without looking and drove his off-hand claws through the man's chest.
The guard gasped. Blood flooded his mouth.
Vorun used the dying body as a shield against Eren's next cut.
The sword hit Lu Or armor instead of enemy shell.
For one terrible heartbeat, Eren saw the man's eyes—clear, apologetic, alive—
Then Vorun flung the corpse at him.
Young Eren caught the weight on instinct and nearly went down under it.
Vorun came through the gap.
The black blade struck.
Eren twisted, but not far enough.
The edge tore across his back from shoulder to lower ribs, cutting through cloak, fastening, flesh, breath. He dropped to one knee with a sound too raw to be called a shout.
In the Hall of Kings, Atum flinched despite himself.
Eren heard it in the present.
"That," he said, "was when pain stopped being information and became weather."
Then he kept going.
Back on the terrace, blood ran hot under his armor. His left hand shook badly. His vision narrowed and widened in ugly pulses. The seal-light beneath the stones was too bright. The corruption too dark. The river too loud.
And still the woman had not lifted her hand from the ancient script.
Silver cracks of light were spreading from her palm into the blue-white circles below.
Her body was paying for every breath the defense remained awake.
Vorun saw that too.
He smiled at her with bloodless cruelty.
"Will you spend yourself for them?"
"Yes," she said.
"You always were wasteful."
Her eyes lifted to him, fierce through ruin.
"And you have always mistaken devotion for waste."
Something moved in Vorun's face then.
Not doubt.
Recognition sharpening into older hatred.
He said her name for the first time.
"Ilya."
The Hall of Kings went still.
Atum looked sharply toward his father.
Aru's eyes widened by only a fraction, but it was enough.
Eren let the name live in the room.
"Yes," he said quietly. "That was your mother's name."
Then he went on.
Ilya did not answer Vorun.
She shouted to Eren instead.
"Your blade!"
He blinked through pain. "What about it?"
"Give it to me!"
He stared at her as if she had lost her mind.
"It is currently busy!"
"Then bring it closer!"
Vorun lunged again.
Eren met him in a shower of sparks, caught one strike, failed to catch the next, and took a glancing cut across the thigh that nearly folded the leg. He staggered backward toward the seal.
Ilya reached for the sword hilt between exchanges.
"Eren!"
"What?"
"Trust me!"
"You people say that too often while dying!"
But he changed the next block lower, letting the recoil bring the blade within her reach.
Ilya seized the flat of the weapon in her bare hand.
Silver light burst where skin touched core-fed steel.
The sword screamed.
Not like metal.
Like memory.
The blue-white circles under the seal answered at once, rising through the blade, through her arm, and into the buried lattice below. The whole center ring blazed brighter. The red-black corruption recoiled a finger's width, as if burned.
Vorun's eyes narrowed.
"There," Ilya said, voice shaking. "Again."
Eren understood enough.
Not everything.
Enough.
He drove forward with both hands on the hilt while she fed that impossible light through the steel. The sword no longer struck like ordinary metal. Blue-white force traced its edge in thin burning lines.
Vorun caught the first blow on hardened forearm shell.
Still gave ground half a step.
Eren followed.
Second cut, high.
Blocked.
Third, low.
Blocked, but slower.
Fourth, straight toward the seal-rim where the corruption was thickest.
Vorun moved to intercept.
Too late.
The blade hit stone.
Blue-white force poured through the old script like riverwater finding a blocked channel.
The red-black line split.
Across the terrace, the buried rings under the landing stones accelerated.
The whole center circle dropped another handspan and turned.
Not mechanically.
Ritually.
Ancient script finding ancient current.
The standing wall of Nam Lapi rose with it in a towering black curve, and for one impossible instant it took shape like a hand.
Not a human hand.
A river's hand.
Even Vorun stepped back then.
Only once.
Enough for every living defender on the terrace to feel the world had changed again.
The captain on the ground forced out a broken laugh. "By the Light…"
One of the remaining guards shouted, "The seal is pushing back!"
Another cried, "No—it's opening!"
They were both right.
Eren stood over the blazing center with blood running down his back, chest heaving, sword bright with mixed silver and blue-white light.
Beside him, Ilya swayed on her feet.
She looked less like a woman now than a body being argued over by pain and purpose.
"You said hold," Eren said.
Ilya gave one ragged breath that might have been a laugh.
"And you are still complaining."
Vorun straightened slowly, black fire dripping from his wounds onto the cracked stones.
His gaze moved from the river-hand above to the turning seal below, then to the two figures standing before it.
When he spoke, all mockery had left him.
"So," he said, "you choose extinction."
Eren lifted his sword again.
"No," he said. "We choose cost."
And above them, the warcraft began to open.
