Chapter Text
The drawer should only have held bandages and stale biscuits. Merlin tugged it open with his hip anyway, trying not to drip blood on the floor, and felt the catch snag halfway. He reached behind the jar of powdered comfrey and found the lip of a false bottom he hadn’t known was there.
A square of oak lifted. Beneath: a ledger, wrapped in a rag the colour of old bone. He had Gaius’s cut between thumb and forefinger, but he didn’t feel it now. The wax seal stamped on the ribbon was Uther’s—lion rampant, sword raised.
He broke it with his thumbnail.
Ink cramped across the pages in Gaius’s careful hand: names, occupations, ages. Margins marked in a physician’s brisk shorthand—fevers, fits, cured—except the words weren’t ailments. “Affinity—water,” “charms,” “seer’s gift,” “none known, suspected harbouring.”
Some lines were underlined twice in red. After those, there were dates. After the dates, sometimes a single word: “Purged.”
Merlin’s breath went thin. He turned a page. Turned another. There were maps, pinned in with a needle so the holes made little constellations. Villages ringed in charcoal. Crosses on crossroads. Notes to the side: “Brother travels for trade,” “Midwife knows the old words,” “Children too young to know.”
There was a section bound with string. He pulled it free and found letters copied out in Gaius’s neat script. “To His Majesty, from G—” He didn’t need the rest to understand.
His stomach lurched. He folded the ledger closed and folded it open again to make the pages lie flat, as if the words might change if they had more air.
Halfway through the book—later than it should have been, earlier than mercy—there was a name that threw him like a hand to the chest.
Balinor of the Western Steppes. Dragonlord. Eldest son.
And under it:
Parents: Hereth and Lysa. Brothers: Ceren (no gift), Talan (no gift). Sisters: Finnah (no gift), Mae. Wife: None listed. Son: Unknown. Associates: shepherds of Craeg Doran. Likely refuge: the old well-road—marked. Notes: Dragonlord power inherited by eldest son, unproven in siblings. Family likely non-practitioners but complicit in harbouring. Recommend swift action.
Date. Seal. A second hand, colder than Gaius’s: “Approved. Dispatch sent.”
Merlin tasted iron. He didn’t realise he’d bitten his tongue until he tasted it again. He saw a firelit cave, a man with tired eyes and a soft smile passing him a heel of bread. He heard the way Balinor had said “son” as if the word was a prayer he’d forgotten until then.
The door below opened and closed. Boots on the stairs. Gaius’s murmuring hum, the way he always hummed when his arms were full of parcels.
“Merlin?” A pause. “What are you—” The steps halted as he saw the desk. The ledger open. Merlin bent over it, hands braced white-knuckled to either side.
They didn’t speak for the length of a candle drop.
Gaius set the parcels down with care. “You’ve cut yourself,” he said, because that was always the first thing he saw. “Let me—”
“Don’t.” Merlin’s voice startled him; hoarse and too quiet. He couldn’t look up yet. “Balinor,” he said, as if naming a saint might help. “You knew.”
Gaius’s years fell over his face all at once. He didn’t come closer. “I knew, yes.”
“And you told the king. Not just—” Merlin made himself flip the page to where the ink bit down. “Not just that he lived. You told him where to find his family.”
Gaius closed his eyes. When he opened them, he didn’t look at the ledger. He looked at Merlin as if he could will him back to a boy who laughed at clumsy potions and said sorry too easily. “I told the king many things,” he said. “In a time when every path led to a cliff, I tried to steer us to the ones less steep.”
“Less steep?” Merlin’s laugh was a small, terrible sound. “They were farmers. One of them a child who hadn’t even learned her letters. The ink says ‘no gift’ over and over, Gaius.” He made himself meet the older man’s gaze then, because he wanted to see it when it broke. “You were the reason they were found.”
Gaius flinched. He put his hands behind his back so Merlin wouldn’t see them shake. “The purge was happening with or without me,” he said. “Uther would have burned the kingdom from the borders in. I thought—” He swallowed. “I thought if I could shape it, I could save some. I gave him names of those who were reckless, dangerous. I tried to protect the others. Sometimes he listened. Sometimes he didn’t.”
“And Balinor’s family?” The taste of iron was back. He could feel the magic under his skin, a storm with nowhere to fall. “Were they reckless? Were grandparents and sisters a threat to Camelot?”
“I believed,” Gaius said, and his voice cracked on the word, “that if I gave him that, he would stop the hunt for the dragonlords. That his rage needed a place to strike and would strike only once. I believed I could—” He exhaled through his nose. “I was wrong.”
“You believed?” Merlin stepped around the table. The ledger slammed shut under his palm, a sound like a clap of thunder in the small room. “You believed, and because you believed, Uther’s men put swords through people who share my eyes, my hair, my name. You believed, and you sat across from me at supper and watched me laugh, and you never told me that my grandparents died so the king could sleep.”
“Merlin.” Gaius reached, then stopped himself. He folded his reaching into his robes. “If I had told you when you came to Camelot, Uther would have smelled it on you. He would have known. I kept you safe by keeping you ignorant.”
“You told me when it suited Uther,” Merlin said, soft as a knife. “When the dragon burned the sky and he needed a leash. You sent me walking to a father I could only have for three days. He died in my arms because you waited until it benefited the king.”
Gaius’s mouth trembled. “I sent you because the city would have burned if I didn’t. Because thousands would have died. I sent you because I thought—because I hoped—you might have one night at least, even if—”
Silence ate the end of the sentence. They both heard it anyway: even if it killed him.
Something in Merlin settled, not gentling but fixing into place like a broken bone forced into its socket. He lifted the ledger again and slid his thumb under another sheaf of letters. “How many?” he asked. “If I start counting, will I ever stop?”
Gaius’s eyes went to the window. To the city beyond, all its roofs and gutters and people wanting their bread. “I don’t count in tens anymore,” he said, almost inaudible. “And I can’t make you think better of me. I can only say that I loved you like a son, and that I made a thousand wrong choices trying to save a thousand others.”
Merlin stood very still because if he moved he might bring the walls down without meaning to. “I’m going out,” he said finally. “Don’t follow me.”
He took the ledger with him.

Kilgharrah listened the way old mountains listen—without speaking until the echo is ready to come back.
“Tell me it isn’t true,” Merlin said into the dark. The dragon’s breath warmed the stone. “Tell me the lines in that book lie.”
Kilgharrah’s great eye opened. “Humans have long made ledgers of their sins and called it record-keeping,” he said. “Your physician wore chains long before I did, young warlock. He chose them himself because he believed they would keep worse hands from clasping the metal. He misjudged the king’s hunger.”
Merlin’s throat pulled tight. “He told Uther where to find them.”
“Yes,” said the dragon. “And Uther went. Did you think the purge a storm that blew from nowhere? It was guided, as all storms are, by pressure and by men who thought themselves necessary.”
Merlin sat down hard on the cold rock. He set the ledger beside him. “I want to burn it,” he said.
“You could,” Kilgharrah said mildly. “You could burn the book, the room it was hidden in, the castle it lives under. You could speak the terrible word and shatter the old man where he stands. The world would be ash and you would still be your mother’s son in the morning, left to live in it.”
Wind moved through the cavern mouth. Merlin realised, distantly, that his hands were shaking. The dragon lowered his head until one slit-pupilled eye filled Merlin’s world.
“There is a cost to mercy,” Kilgharrah said, “and a cost to vengeance. You know already which price you can afford. Go and pay it.”
Merlin picked up the ledger.

Craeg Doran had once been a place where chickens strutted and somebody’s washing line snapped in the wind. Now the huts were humps beneath grass and nettles, and a blackthorn had grown up through the well like a stake through the heart. He found a brooch half-buried at the lip of the old road—a tin circle with a pressed flower inside, the resin gone cloudy. He wiped the dirt with the edge of his sleeve and saw a smear of blue speedwell, the kind his mother had tucked behind his ear when he’d been very small.
He didn’t cry then. He stood and listened to the silence until the silence became a sound of its own, until the empty air was crowded with people the book had turned to ink.
On the way back to Camelot, he walked as if through water. A farmer nodded at him. A child played with a hoop. The city had learned to live around the bones.
Gaius was waiting at the table, the room dark but for one candle stub. He didn’t look up when Merlin entered. The brooch clicked soft on the wood when Merlin set it down.
“This was on the way to the place where my family died,” he said. His voice could have been anyone’s. “You can keep it. You like to collect reminders.”
Gaius closed his eyes. “What do you want me to say?”
“There’s nothing you could say,” Merlin answered. He slid the ledger across. “This is truth. I won’t let you hide it from yourself again.”
Gaius’s hands hovered above it and didn’t touch. “Are you going to tell the king?” he asked, and it was almost a child’s question.
“I’m going to tell the truth to the people who deserve it.” Merlin let his gaze rest on the man who had taught him how to bind wounds and brew pain-draughts and stand quietly where everyone shouted. “Not him.”
Gaius nodded once, as if a blade had just missed him. “Arthur will—”
“Arthur will hear what he needs to hear.” Merlin swallowed. “But you and I—” The words crowded his mouth and fought each other. He forced them out in order. “You were the first person in this city who was kind to me. You gave me a bed and a place to put my shoes. You’ve patched me up more times than I can count. And you have done unforgivable things.”
Gaius’s shoulders sagged. He looked old enough to crumble. “Yes.”
“I won’t kill you,” Merlin said. The magic stirred, listening. He made it be still. “I don’t think that would make the dead any less dead. But I can’t be your boy anymore. I can’t let you be my conscience.”
Gaius nodded, because there was nothing else to do.
“Tomorrow,” Merlin said, “you will go to the memorial ditch outside the west gate and dig until your hands bleed. You will dig until you find where the earth turns dark in a seam, and you will know who lies under it because you sent them there. And then you will come back and tell me their names, aloud, without writing them down.”
Gaius put his hands flat on the table so Merlin wouldn’t see them tremble. “And after that?”
“After that,” Merlin said, and suddenly he was so tired he could have slept on the floor, “we will see if there is anything at all left to build from.”
He turned toward the ladder. Halfway up, he stopped, reached out, and took the candle. He didn’t want Gaius to sit in the dark with the ledger and his thoughts. He wanted him to see everything.
In the sudden blackness below, Gaius let out a breath that might have been a sob, or a prayer, or nothing at all.
Merlin lit a new candle with a flick of his fingers out of habit, and the flame came easy. He watched it for a long time, then blew it out and let the night be what it was.
In the morning, he would bury the brooch. In the morning, he would take the ledger to a smith and have the seal melted down. In the morning, he would begin the work of separating the good he’d learned from the hands that had taught it.
For now, he lay down in the narrow bed above the room that smelled of dried valerian and old secrets, and listened to Camelot sleep. He thought of a man by a fire, of the word son said soft for the first time, of a village where nettles grew too tall. He thought of Gaius, whose love had been a knife sharpened on the stone of fear until it cut the very thing it meant to protect.
He thought: I will not be that.
And when dawn came, he rose.
