For one suspended moment on the servant stair, no one moved.
The knock had come from below them. Not from the lower terrace. Not from the visible palace foundations. Deeper.
And in the pale face of Deputy Council Clerk Saben, Talem saw the worst part clearly: the man had expected it.
In the Hall of Kings, years later, Eren said, "A kingdom changes when hidden paths matter more than open roads — and men choose them long before wise rulers ask where they lead."
Then he returned to the stair.
Saben was shaking now, not with the fear of arrest, but with the fear of being overtaken by something he had hoped to reach first.
Talem kept the blade under the man's jaw and asked, very softly, "What is down there?"
Saben's mouth trembled. "I don't know."
Talem's expression did not change. "That answer has become tired."
"It's true!"
"One honest word buried in a frightened lie remains mostly lie."
The knock came again. Closer this time. Not louder. More certain. The old stone of the servant stair seemed to carry it along the bones rather than through the ear.
Iren tightened his grip on Saben's robe. Pevo looked down the dark run of steps with the face of a boy discovering that the palace had always been older than safety.
Talem said, "Who told you about the underpath?"
Saben's eyes stayed fixed below. "I only knew there was an old route."
"From whom?"
Silence.
Talem pressed the blade a hair closer. "From whom?"
"Saben!" came a hiss from below.
Every head snapped downward.
A figure stood in the darkness at the foot of the lower turn, half-hidden by the service arch, lamp in one hand, hood drawn high. Not a guard. Not a servant. Too still for panic. Too well placed for accident.
The figure saw the tableau at once: Saben pinned, Talem poised, Iren armed, Pevo frightened but standing.
Then the lamp dropped. Oil burst across the stair in a sheet of flame.
Iren swore and yanked Saben backward. Pevo stumbled into the wall. Talem leapt the first tongue of fire and hit the lower turn at a run, but the hooded figure had already vanished through the narrow arch below.
"Pevo!" Talem shouted. "Upper cross-stair! Cut the west!"
The boy bolted.
"Iren, keep him breathing!" Talem snapped, and was already gone.
The arch below the servant stair opened into a corridor no one had used in years. The air was colder. Dust lay thick except where fresh footfalls cut through it. The walls were old river-stone, darker and rougher than the dressed palace foundations above. Water hissed somewhere unseen behind them.
Talem ran low and fast. He had stopped smiling three turns ago.
The corridor forked almost at once: one path slanting toward the lower western vaults, the other dropping more steeply toward the buried supports beneath the old terrace.
He knelt for one breath. Fresh ash on the left wall from the dropped lamp. Wet grit dragged right. A thread of robe-cloth caught on a stone seam.
Right. Toward the lower terrace. Toward the seal.
Talem ran again.
Behind him, somewhere above, Saben began shouting. Good. That meant Iren had made him understand the value of being useful while still whole.
The corridor tightened, then widened into a low chamber where old maintenance tools lay in collapsed racks and a dry channel crossed the floor like a dead stream. Beyond it, another arch opened toward darkness that should not have been carrying river air — and yet did.
Talem slowed just enough to draw his short blade.
"Whoever you are," he called, "this would be an excellent moment to become disappointing and surrender."
No answer.
Then: movement at the far arch. A glint. Steel.
The hooded figure struck from the dark with the speed of someone who had planned the space. Talem turned the first knife aside by instinct and heard it crack against stone past his ear. The second came lower. He shifted, let it graze cloth instead of flesh, and drove forward into the attacker's body before a third could be drawn.
They hit the wall together. The hood fell back.
Not a servant. Not a noble. A palace records officer he knew by sight and disliked by instinct — Clerk-Marshal Saben's superior runner, a man called Edo, too forgettable in daylight and therefore exactly the kind of man people used for midnight work.
Edo tried to bite him. Talem admired the desperation. He slammed the man's wrist against the wall until the knife dropped, then hit him once across the temple with the hilt and sent him folding to the floor.
"See?" Talem muttered.
He grabbed Edo by the collar and hauled him half upright. "Who sent you?"
Edo laughed blood into his own teeth. Talem hated professionals more than cowards. They bled with intention.
Another sound came from beyond the arch.
Not a footstep. Not human breathing. A scrape. Then a wet, patient drag.
Talem's attention shifted past Edo into the deeper dark.
The man on the floor saw it and smiled. That was bad.
Talem released him and rose slowly.
The corridor beyond opened into one of the old subfoundation passages shown on the stolen maps. Low ceiling. Side channels. Water-dark cutstone. And on the floor beyond the arch, half in shadow, lay a shape too still to be living and too deliberate to be dead.
Black shell. One arm wrong. Head turned toward the sound of human breath.
A surviving invader. Not from the roads this time. Not a stray in the reeds. Inside the palace underpaths.
Talem's face went very calm.
So that was the game. Not merely political witness. Access. Guided access. Someone had meant to bring eyes — or perhaps something worse — to the lower terrace before dawn through forgotten foundation ways.
Edo pushed himself up behind him.
Talem did not look back. "Don't."
Edo ran. Talem pivoted and threw his second blade. It buried in the runner's thigh. He screamed and crashed across the dead channel.
From the darkness beyond, the black-shelled shape moved. Not quickly. Injured, then. Good.
Talem stepped back to widen the angle and buy breath.
He needed Letho. Needed Eren. Needed men with shields and less appreciation for elegant disaster. Instead, what he had was: one bleeding conspirator, one hidden underpath, one palace-bred invader surviving where no invader should have survived, and a kingdom above them that did not yet know how close the war still lay under its own floors.
The invader raised its head fully. Its eye slits glowed red in the dark.
Then, in a voice torn but still human, it said one word.
"Open."
Talem stared. Then, because the world had clearly decided to become unbearable, he answered aloud.
"Oh, absolutely not."
From behind him came Pevo's voice, breathless and far too near. "Talem!"
Good boy. Bad timing.
Talem did not turn. "Run back. Find Prince Eren. Tell him the path beneath the palace is not empty."
Pevo stopped dead.
The invader in the arch shifted one broken step forward.
Talem lowered himself into guard, eyes never leaving it.
"And," he added, "this would be an excellent time for everyone above us to stop pretending dawn is their real problem."
The invader took another step.
And somewhere deeper below, beneath even this old hidden passage, something knocked back.
