Chapter 42: The Lesson in the Knife

Catus moved like smoke, and the knife was already a whisper of silver in the dark before Victor’s hand found his gladius. The black blade came free of its scabbard with a sound that was almost a sigh, and the hum began at once, that low, hungry thrum that Victor had learned to hate. He raised it, and Catus’s knife rang against the steel, a single, singing note that hung in the air like a question.

They broke apart.

The ash tree groaned behind Victor, its burden shifting as if the dead man it held might yet climb down. The moon was high and thin, and the clearing held its breath. Victor could smell the river, the cold mud, the iron of his own blood still drying on his knuckles. He could smell Catus, too, a smell of old dust and older stone, like a crypt opened after a century.

“You want to kill me,” Victor said. Not a question.

Catus circled, low and easy, the knife held loose in his fist. “I want to teach you. There is a difference.”

“Your knife says otherwise.”

“My knife is the lesson.” Catus lunged, and Victor moved. The gladius swept up, but Catus was not there—he was already past, the blade kissing the air where Victor’s throat had been. The hum of the black sword rose in pitch, and Victor felt the familiar heat bloom in his chest, the brand of Mars burning through his tunic. The strength came, swift and terrible, and he turned and struck.

Catus caught the blow on the flat of his knife and was flung backward, skidding across the damp earth. He came up laughing, a sound like stones grinding.

“Good,” he said. “Again.”

They went at each other in the ruin of the clearing, and Victor learned. He learned that Catus knew every step, every feint, every trick the gladius had been taught in a hundred years of Roman camps. He learned that Catus’s knife was never where it seemed, that the shadow-guide fought like a man who had died long ago and had nothing left to lose. And he learned that the more he drew on the war-god’s blood, the faster Catus smiled.

“You feel it now,” Catus said, dodging a thrust that would have opened his ribs. “The hunger. The want. That is the blade’s truth. That is your truth.”

“I am not the blade,” Victor snarled.

“You are what you carry.” Catus’s knife flicked out and scored a line across Victor’s forearm. The blood welled, and the silver in it caught the moonlight. “And what you carry is older than Rome.”

Victor looked at the wound. The silver blood did not drip; it moved, slow and thick, as if it were alive and considering its next step. The black gladius hummed louder, and he felt the pull, the urge to drive the blade into Catus’s chest and watch the light leave his eyes. It would be easy. It would be a mercy, to stop the man’s endless riddles with one clean stroke.

He did not.

He planted his feet instead, and he let the hum fill him, and he did not move. Catus came in fast, the knife leading, and Victor stepped into the blow. The blade took him in the shoulder, a shallow, burning cut, and Victor’s free hand closed around Catus’s wrist.

They stood there, locked, close enough that Victor could see the flecks of grey in the man’s beard, the lines around his eyes. Catus was not smiling now.

“You let me cut you,” Catus said.

“I wanted to see your eyes,” Victor said. “When you thought you had me.”

Catus’s grip loosened. The knife fell to the earth with a soft thud. The shadow-guide looked at Victor, and for the first time, there was something other than mockery in his gaze. Something like respect. Something like fear.

“You are learning,” Catus said. “But the lesson is not finished.”

He pulled free and stepped back, and Victor let him go. The black sword lowered, its hum fading to a murmur. The night was quiet again, save for the river and the wind.

“What did you mean,” Victor asked, “when you said she lies?”

Catus bent and retrieved his knife, sliding it into its sheath. “The queen of Palmyra. Zenobia. She told you she would give you a kingdom, or a purpose, or a place at her side. She did not tell you what she would take in return.”

“She wants my blood.”

“She wants your blood,” Catus agreed. “And your sword. And your name. She would make you a tool, and when the tool was dull, she would set it aside. That is the way of queens.”

“And Postumus?”

Catus was quiet for a long moment. The moon moved behind a cloud, and the clearing went dark, and when the light returned, his face was carved from stone.

“Postumus believes the prophecy. He believes you will crown him emperor of the world. He drinks your silver blood and sees a throne. He does not see the price.”

“What price?”

Catus looked at the black gladius in Victor’s hand. “Ask the blade. It knows.”

Victor looked down. The sword was still, but he felt it waiting, patient and vast, like a beast at the bottom of a well. He thought of the amber-eyed creature in the mist, the thing that had watched him from the river, and he knew, with a cold certainty, that Catus was telling a truth of some kind.

“You came to me,” Victor said. “You came to warn me. Why?”

Catus smiled again, and it was not kind. “Because I was like you once. A man with a god’s blood and a monster’s blade. I know what you are becoming, and I would rather see you become it than watch the world burn without you.”

“Becoming what?”

Catus did not answer. He turned and walked toward the river, and his voice came back over his shoulder, thin and cold as winter light.

“A king, Victor. A king of ash and silver. The only kind the world will let you be.”

Victor stood in the clearing, the dead man watching from the ash tree, the black sword humming at his side. The river ran on, and the night pressed close, and somewhere beyond the dark, the war was still marching. The arrows would be falling. The legions would be roaring.

He did not follow Catus.

He turned instead, and he walked back toward the camp, and the silver taste of dawn was already on his tongue.
