The training ground was silent at this hour.
No clash of steel. No bark of orders. No shuffle of boots against packed earth. Just Taehyung, alone in the grey belly of early morning, and the fire that lived inside his skin.
He moved through the forms slowly at first the way his first instructor had taught him, back when he was small enough that a practice sword looked ridiculous in his hands. Stance. Pivot. Strike. Breathe. The motions were old enough to live in his bones, and for a moment, just a moment, they quieted everything else.
Then he sped up.
Strike. Strike. Turn. The fire answered him without being called, curling from his knuckles in thin ribbons, scorching the air where an opponent's throat would have been. He pushed harder. His breath came ragged. Sweat broke across his back and chest and he ignored it, ignored the ache already building in muscles that had not truly rested in days.
He could not afford to rest.
How many?
The question rose the way it always did sudden, uninvited, like a blade between the ribs.
How many of them went into the ground because you were not enough?
He struck out and the fire roared, a burst of it that charred the wooden post before him black. He stared at what he had done. His chest heaved. The post stood there, ruined, and said nothing.
Thirty-one men. He knew the number without having to think. He would always know the number. Their faces had already begun to blur at the edges in his memory the way faces did when you did not want them to, when grief was too large to look at directly but the number stayed sharp. Thirty-one. Sons. Brothers. Men who had followed him not because they were commanded to but because somewhere along the way they had decided he was worth following.
He had not been worth it.
Taehyung exhaled and moved again, but the rhythm was gone. His body was still moving through the forms and his mind was somewhere else entirely, somewhere cold and ugly, cataloguing every decision that had led to thirty-one men dying with his name on their lips.
More power.
The thought was not new. It had been circling him since the battlefield, since he had stood in the ruin of everything and understood with horrible clarity that strength and fury were not the same thing. He had fury in abundance. He had always had fury. It had never been enough.
He needed power. Real power. The kind that could have held a line. The kind that could make an enemy think twice before testing him.
The fire rippled across his forearms and he looked down at it that old curse, that old companion and for the first time in a long time he did not hate it. He turned it over in his mind the way you turned a weapon over to inspect the edge.
Not enough.
He breathed out.
The thing he had been refusing to think about for three days settled over him now like a stone dropped into still water. Yul.
Prince Yul.
The name alone did something complicated to the inside of his chest a tangle of things he could not cleanly separate. Old memory. Old loyalty. Something that had once been close enough to brotherhood that he had not known what to call it. And now.
Now he knew what Yul was.
He knew what Yul had chosen. What Yul kept choosing, every day he did not undo what had been done, every day he looked at the shape of things and decided it suited him. Taehyung had spent a long time telling himself it was complicated. That there were things he did not understand. That perhaps if he waited long enough there would be an explanation that made sense of all of it.
He was tired of waiting.
He stopped moving.
Stood in the center of the training ground with the fire guttering low around his hands and his lungs burning and sweat cold on his skin, and he let himself think the thought he had been flinching from.
If he named Yul an enemy truly named him, without the hedge, without the part of him that still reached for what they used to be then there was no going back. The door closed. Whatever remained between them became something sharp and entirely different.
But thirty-one men.
Thirty-one men who had trusted him.
Taehyung tilted his head back and looked at the sky, that pale early grey, and said nothing, because there was no one to say anything to. The ache in his chest was not grief alone it was something harder. Something forming. The shape of a decision that had not finished becoming itself yet, sitting in the center of him like a coal.
He brought his gaze back down.
Lifted his hand.
The fire rose.
He stared at it small, controlled, waiting and for the first time he did not think about what it had cost him. He thought about what it could still do.
More. He would need more than this. More than he currently was. Whatever it took, wherever he had to reach to find it he would not stand over another thirty-one graves and feel this way again.
He closed his fist.
The fire died.
And Taehyung stood alone in the silent training ground as the sky slowly, reluctantly, began to lighten and made himself sit with the thing he had just decided, because decisions like this deserved to be felt fully before they were carried forward.
Prince Yul.
Enemy.
The word settled.
And did not move.
