"What's the word mortals use?" Nameless said at Aelius's answer. The layered voice carried something that might have been exasperation if exasperation could be distributed across several dozen mouths simultaneously. "Cliché, I believe it is." Several of the mouths along its nearest arm closed and reopened in a slow, rippling motion. "An acceptable answer. Neither wrong nor right. But you understand the concept, I can feel it in your biology, however false it might currently be."
Nameless sighed, the motion traveling outward from its torso through every mouth along its arms in a soft, synchronized ripple that managed to convey annoyance without any single part of it committing to the expression fully. "You are more than the harbinger of rot and decay," it said. "You are the rot and decay. The distinction matters more than you've allowed yourself to sit with properly." The skull angled forward slightly. "You understand this now. And you have grown because of it. The months here have produced something stronger; I won't diminish that. But you have only once truly used it," it continued. "During our first meeting." The whisper layer of its voice surfaced briefly, something in it that was not quite reverence and not awe, but a mix of both. "You used your own blood to injure me. I was genuinely surprised you were capable of that." Several of the mouths along its uppermost arms opened slightly, as though the memory of it was still producing something worth examining. "You didn't understand what you had done in the moment. You acted on instinct, on something that reached past your training and your conscious understanding of your own magic and found something older underneath it." The skull tilted. "But in the moment you used that spell, that was the strongest you have ever been. Before or since."
"I've used that spell a dozen times since then, in the same way as well." Aelius said. "But you're saying it's always been weaker?" His eyes closed for a moment, replaying it. The day that spell had first appeared, the day he had reached past everything he understood about his own magic and found something underneath it that he hadn't known was there. The day he had met Alaric. The day everything had started going wrong.
"You've used the spell," Nameless said, before he could form the follow-up. "But you've never become it. Not like you did that day." Several of the mouths along its arms shifted, opening and closing in a rhythm that felt like searching for language rather than deploying it, which was unusual enough that he paid attention to it. "It's difficult to explain. It sits closer to theory than logic, which I recognize is an unsatisfying thing to tell someone who exists around the second." The skull tilted. "But try to follow the distinction. When you cast that spell now, you are directing your magic toward a specific output. You have a shape in mind, a result you intend, and you move the magic toward it. Yes?"
"Yes," Aelius said.
"That day, you had none of that," Nameless continued. "You weren't using your magic, you were your magic, completely and without the intermediary of conscious intent." The whisper layer surfaced briefly. "And in those seconds, you truly injured me. Which, I want to be clear, very few things that have ever existed have managed at all, let alone accidentally."
"So how do I repeat that?" Aelius said, "You plan on attempting to kill more people I care about?" He said it flatly, clearly expecting confirmation rather than denial. It was the most logical answer. It had worked once. Nameless was nothing if not practical about outcomes.
"Oh, it would be more than an attempt, little godling," Nameless said, and the amusement in all three layers of its voice carried the particular weight of something that meant what it said. "But no."
It began expanding. Not the way it had shifted before, the gradual, weather-like changes in form that Aelius had grown accustomed to over the months. This was immediate and enormous, the four arms spreading outward and merging with the torso as the torso itself grew, the mouths along every surface combining and combining again, dozens becoming scores becoming one singular aperture that widened as the thing that had been Nameless rose above the ruins of the castle and kept rising, the sky disappearing behind the sheer mass of it, the courtyard swallowed in shadow. The single merged mouth was larger than the castle had been at its height, larger than anything Aelius had ever stood in front of that was still technically one thing rather than a landscape.
"You," the voice said, now coming from everywhere rather than any single point, the three layers so large they had stopped being distinct sounds and become more like weather, "are going to kill two birds with one stone." The mouth opened fully as the words finished. "Your final task for training. One, I will leave you to discover the shape of it on your own." The voice dropped, the whisper layer suddenly dominant even at that scale. "Kill this. Until you do, you will never achieve what you want."
Something crawled out of the mouth. It came slowly, which made it worse. Fast things announced themselves and were gone. This took its time, one massive limb appearing first, then another, the sound of it preceding the sight of it, a wet, grinding drag against the stone of the courtyard that the graveyard absorbed without echo. Then the head cleared the mouth and Aelius got his first proper look at it and understood immediately why Nameless had chosen to deliver it this way rather than simply describing it.
A hundred feet from tail to snout. Forty feet or so at the shoulder, maybe more in places where the body refused to hold a consistent shape. Even at that scale, it was perhaps a third the size of Acnologia, which was the single most unwelcome contextual reference his mind could have chosen to provide in that moment, and he noted it and set it aside because there was too much else immediately demanding attention.
It was a dragon in the way that a corpse left in standing water for a month was still technically a body. The shape was there, the general architecture of something draconic, four legs, a tail, a head with a jaw that could swallow a building. But every surface of it had been claimed by something that had clearly been working on it for longer than it had been alive, or perhaps from before it was alive; it was difficult to tell where the corruption ended, and the original began because the answer was probably nowhere.
The scales, where scales still existed, were the green-black of something from a swamp, slick with a film that caught the gray light and turned it the color of infected wounds. Between them, where the corruption had progressed furthest, the flesh had swollen outward into great pustulent mounds that moved with the slow, independent rhythm of something beating, and its breathing, some weeping a fluid the color of yellow bile that steamed faintly where it struck the ground, others distended tight as drums and visibly pulsing. Several had burst at some point and never closed; the resulting craters crusted at the edges but still seeping at the center, ringed with a growth that was neither scale nor skin but that glistened and occasionally twitched.
The legs were the wrong shape for a dragon's legs, too wide and too low, the joints reversed in two of the four in ways that should have made movement impossible and clearly hadn't, because it moved, slowly, but it moved, each footfall leaving an impression in the stone that filled immediately with the runoff from its body. Mushrooms had colonized the folds of skin along its underbelly, pale and enormous, their caps brushing the ground as it walked and releasing clouds of spores that drifted in the still air of the graveyard like the world's least welcoming snow. Where the tail dragged behind it, it left a trail that the stone absorbed with visible reluctance.
The head was the worst of it. The jaw was too large for the skull, hanging open at an angle that suggested the tendons responsible for closing it had either rotted through or given up, revealing a mouth interior that was less teeth and more a collaborative ecosystem of growths and parasites and things that had taken up residence in the soft tissue and made modifications. The tongue, what remained of it, moved in the back of the throat with the slow, purposeful motion of something that was not a tongue anymore and knew it. One eye was sealed shut beneath a growth so large it had reshaped the entire left side of the skull. The other was open, and it was the only part of the creature that looked genuinely alive in any conventional sense, pale yellow and tracking him with an attention that the rest of the body's slow, geological movement made somehow more unsettling rather than less.
It smelled like the world's worst scents compressed into a single source. Rot and copper and the specific sweetness that decay produced at a certain stage that his body had catalogued as danger before his conscious mind finished processing the input.
"A corruption of your grandfather's making," Nameless's voice said, from everywhere and nowhere, the massive mouth already receding back toward something approaching its original scale. "The last of its kind. Rotten down to whatever passes for its soul." A pause. "Meet the Toad Dragon, little slayer. Try not to die," Nameless said, and then Nameless was gone, the way a thought is gone when something louder replaces it, present and then simply not, no ceremony, no transition, just absence where something incomprehensible had been a moment before.
Aelius did not have time to process that. Because the Toad Dragon moved. For something of its size, the speed of it was an insult. Not fast in the way a predator was fast, sharp and purposeful, but fast the way a collapsing building was fast, the kind of speed that was more mass, than actually trying to be fast. One of the reversed-joint legs drove into the courtyard stone, and the entire ground bucked underfoot, cracks splitting outward from the impact in jagged lines, and Aelius was already moving, vaulting sideways off a section of collapsed wall as the thing's jaw dragged through the space he'd occupied half a second before. The fluid it left behind steamed where it hit the ground.
He landed and immediately moved again as the tail swung in a slow arc that would have been easy to read on anything smaller and was instead nearly unavoidable at this scale simply because of how much of the courtyard it consumed. He cleared it by less than he would have preferred, felt the displaced air drag at his coat, and put another twenty feet between himself and the creature before stopping to breathe.
The spores were already drifting toward him. He breathed them in without thinking, the way he breathed in everything. His body processed the corruption the same way fire ate kindling, not as damage but as fuel, drawing it in and burning it clean. The fluid that had splashed across the lower half of his coat during the near miss was already dissolving where it touched him, consumed rather than absorbed. The rot in the air, the specific sweetness of advanced decay that should have been eating at his lungs, settled into him instead like something returning home. That part, at least, was fine.
The rest of it was not. He sent a wave of plague-laced magic into the creature's flank as it turned toward him, a spell he'd used to reduce things considerably larger than men to mulch in under a minute. It struck, but the Toad Dragon did not slow down, so he hit it again, harder, pulling more from the reservoir of power that sat behind his ribs like a second heartbeat. The spell bloomed across a section of its underbelly, green-black and virulent, the kind of magic that had earned him his title and his seat among the Saints and the particular expression Makarov got whenever someone asked about him in polite company. The creature shook itself, the way a dog shakes off water, and kept coming.
Aelius moved again because standing still was the only thing that would definitively end the fight in the wrong direction. He cleared the remains of a collapsed archway, landed on the other side, and had approximately one second to understand the problem before the follow-up swing of the thing's foreleg forced him into motion again. His magic was not hurting it. He understood why, academically, even as he was vaulting off a section of wall to avoid being pressed into it. Corruption already lived in every cell of that creature. Rot had claimed it so thoroughly that there was nothing left to rot further; his magic arrived and found its work already done, poison seeking to poison what was already poison, fire thrown into a furnace. The dragon had been marinating in exactly the kind of filth his power was built to inflict for longer than it had probably been alive in any meaningful sense. There was no threshold left to push it over. It was already past every threshold.
Which meant he could not hurt it. He knew what that meant. He knew what the answer was, had known it the moment Nameless finished speaking, and the shape of the problem had clicked into place with the particular clarity of something designed specifically for him. He even knew, in the abstract, what it would require, but understanding and the doing were separated by a gap he currently had no idea how to cross.
He threw another spell, not because he expected it to work but because doing nothing while something forty feet tall at the shoulder tried to step on him was a short-term strategy with obvious limitations. The magic hit, bloomed, spread, and the dragon rolled its one working eye in his direction with the slow patience of something that had stopped registering pain so long ago it no longer remembered the concept.
Aelius landed badly on a patch of courtyard where the stone had been turned to something soft and yielding by the creature's runoff, caught himself, and came up already moving. His coat was beginning to show the marks of the engagement, tears where he'd been clipped, staining along the hem from the ground itself. He was not injured. He was also not winning, was not close to winning, was not even operating in the same conceptual neighborhood as winning.
He hit the creature again across the jaw as it swung toward him, instinct rather than strategy, buying distance. The spell scattered across corrupted scales and accomplished nothing.
He knew what he needed to do. He had no idea how to make himself do it. It was all he could think of, other than dodging, of course. The courtyard buckled again as the Toad Dragon repositioned, one of the great legs punching through the stone entirely and leaving a crater that immediately began filling with runoff. Mushrooms were already sprouting along the edges of it. The spore clouds drifted. The one pale eye tracked him across the rubble with an attention that felt, deeply and incorrectly, personal.
It had taken Aelius four hours to find somewhere the dragon couldn't follow him. Four hours of running, of dodging, of losing pieces of himself and regrowing them between one step and the next. An arm gone to the sweep of a corrupted claw, back before he'd cleared the next archway. Two fingers sheared off when he'd misjudged a gap in the tunnel mouth, regrowing before they'd even finished hitting the ground. A chunk of his side, once, when he'd underestimated how far the thing's tail could swing and paid for it with about six inches of his left flank. All of it was back within seconds, which was the only reason he was currently sitting in a chair rather than being absorbed into the cavern floor somewhere beneath the Labyrinth.
It was still profoundly irritating to be used to it. The tunnel had saved him in the end, a low passage cut into the base of one of the outer walls that the dragon was simply too large to follow him through. He had heard it trying anyway, the wet grind of corrupted flesh pressing against stone too narrow to accommodate it, and then, eventually, the sound of it giving up and retreating back into the dark. He had kept moving for another twenty minutes after the sound stopped, because assuming it had given up was the kind of optimism that killed people, and he had not survived this long by being optimistic.
The house he'd found was near the edge of one of the towns that ringed the Labyrinth's outer territory. Most of it had collapsed inward on itself long ago; the roof had partially caved, and one wall bowed outward at an angle that suggested it was more committed to falling than to standing. But the floor held, and one room in the back had escaped the worst of the damage, and in that room there was a chair that was, against all reasonable expectation, still largely intact, so he sat in it. The chair creaked once under his weight and then settled, apparently deciding that it had survived everything else and saw no reason to fail now. Aelius appreciated the sentiment. He rested his elbows on his knees and stared at the wall across from him, which had a crack running from the floor to the ceiling that let in a thin strip of the gray sky outside, and he thought.
His magic was not going to win this. He had understood that during the fight, he had understood it clearly from the third pestilent arrow onward and had kept throwing them anyway because understanding a problem and accepting it were different things, and he had never been good at accepting things. But twelve arrows in, aimed at every soft point the creature had, the good eye, the underbelly, the places where the flesh had swollen thin enough to see what lay beneath it, and not one of them had done anything he could honestly call damage.
The corruption had claimed every part of that dragon. There was nothing left for his magic to rot that hadn't already been rotted further than anything he could achieve. He was a plague god slayer throwing plague at something that had already become the plague itself, which, in retrospect, was the kind of poetic failure that Nameless would have found deeply amusing, and he was absolutely not going to give it the satisfaction of saying so out loud.
He pressed the back of one hand against his mouth and stared at the crack in the wall The dragon's poison hadn't touched him either, which he'd noticed during the fight and filed away as the only thing in the last four hours that had gone in his favor. Every cloud of spores, every splash of corrupted fluid, every time the thing's breath had reached him with its particular quality of wrongness, all of it moved through him the same way everything moved through him, fuel rather than damage, his body drawing it in and converting it without ceremony. He'd actually felt his reserves climb slightly during the fight, which was grimly funny given that every other aspect of the engagement had been a comprehensive disaster.
So the dragon could not kill him with its rot, and he could not kill the dragon with his.
He leaned back in the chair and looked at the ceiling, where the plaster had fallen away to show the bones of the structure underneath, old beams gray with age. Something had nested up there once, long ago; the remnants of it pressed into the corner. The room smelled of cold stone and time.
The principle was not complicated. It was so clear it almost seemed obvious, and the fact that it seemed obvious was precisely what made him distrust his ability to actually do it, because things that seemed obvious in theory and were genuinely simple in practice did not usually make him feel the way he currently felt, which was like standing at the edge of something very high with no particular confidence that he could fly. His wings twitched with that thought, like they were angry he had forgotten he could fly, something he did attempt against the flightless dragon, only to learn the thing's tongue was longer than it was, and faster than it was.
He was the rot and the decay. Not someone who used it, not someone who directed it. The thing itself, and the dragon was the problem built specifically around that distinction, because the dragon's corruption and his corruption were not different things in the way that mattered. They were the same. His magic, arriving at its surface, was the same as someone trying to wound a fire with a burning brand. The categories did not permit the outcome.
The chair creaked beneath him as he shifted, and the sound was the loudest thing in the room for a long moment.
He turned his hand over, looking at the palm. His own magic stared back at him from underneath the construct of skin and bone, the substrate running quiet and constant, the same way it had been running since Tenrou. He had learned to read it over the months with Nameless, had learned to feel the texture of it the way a man learned to feel the grain of wood he worked with daily, intimately and without having to look directly at it.
He knew exactly what he was.
He had known it in the way words conveyed things since Nameless told him, had carried it through the guild and the porch and Vanessa's arms and Macao's office, this fact sitting in the center of everything he did like a stone in still water. A construct. His magic arranged into the shape of a person and held there by something that had reached past conscious intention and done what needed doing because the alternative was nothing.
The thing was, he had been doing that his whole life in one way or another. Arranging himself into whatever shape the situation required and holding it there until the situation changed. He was very good at that. He had spent years perfecting it, the mask, the distance, the careful management of exactly how much of himself any given moment was allowed to see.
And that, he thought, staring at his palm, was precisely the problem. He had spent his entire life becoming very skilled at being adjacent to what he actually was. Directing it, shaping it, running it through the framework of intention and spellcraft and conscious output until what arrived on the other side was useful and controlled and his. Nameless had spent months stripping the waste out of part of that process, and he had gotten extraordinarily good at the stripped-down version of it.
He closed his hand slowly and rested it back against his knee. There was something deeply unpleasant about arriving at a problem whose solution was not a thing he could learn by doing it wrong enough times until he did it right. Every other wall life had put in front of him had eventually yielded to iteration. He let out a slow breath through his nose and looked at the crack in the wall, the thin strip of gray sky visible through it. The light had shifted slightly, the gray deepening toward the particular quality it got when the Labyrinth's version of evening was making its way in, which meant he had been sitting here longer than he'd realized.
His reserves were fine. The construct was stable. He wasn't tired in any way that sleep would fix because sleep wasn't something he needed anymore, which was one of those facts he had disliked, as it only further solidified his inhuman ideology.
He could go back over. There was nothing physically stopping him from going back into the tunnel and finding the dragon again, nothing except the knowledge that going back down right now would produce exactly the same result as the last four hours, and four more hours of that would produce nothing except a more thoroughly explored version of the same dead end.
So he sat. The crack in the wall let in the gray. The house settled around him with the small sounds of old structures talking to themselves. Somewhere far below, the Toad Dragon moved with its slow, patient weight, the pulse of that place beating on without it. It wasn't going anywhere. This place was made to seal, and seal it would. The dragon was far too big to fit through the cracks, unlike a human, meaning it would stay down there until he figured out how to actually kill it, or until he conceded that he couldn't, which was not a concession he was prepared to make.
He just didn't know what came between now and then.
