Chapter 1: The Comet's awakening

The air in Ozai’s chamber was thick enough to taste—sandalwood, hot stone, and the sharp, metallic promise of the comet bleeding through the high windows. Crimson light painted the obsidian floor, a silent, pulsing beat that matched the throbbing in his veins. He stood before the arched vista of the approaching inferno, the fabric of his uniform growing taut across his back.

He felt it before he saw it. A deep, cellular ache, a seeping warmth that was more than power. It was a metamorphosis. The ornate gold thread along the seams of his black upper garment began to bite into his skin. He looked down, his breath catching not in alarm, but in a slow, dawning hunger.

The seven polished jet buttons down his chest were straining. The tight weave of the fabric groaned. Between the gaps, where the threads were stretched white, he saw the swell of his own pectorals, now dusted with a coarse, dark hair that hadn’t been there that morning. He dragged a finger across one pec, feeling the new texture, the dense muscle beneath. A raw, musky scent hit him—his own scent, amplified, feral. It drew him in.

He raised his arm, bending it at the elbow, and ducked his head into the space beneath. The heat there was immense, damp. The hair was thicker, a dark jungle matted with salty sweat. He inhaled deeply, his nostrils flaring, filling his skull with the pungent, primal aroma of his own transformation. His cock, already hard, gave a violent, demanding throb against the confines of his pants.

The tailored cloth was punishing now. It dug into the swelling bulk of his thighs, clenched around the tightening globes of his ass. The front of his trousers was a ridiculous tent, the central button bowing outward with a faint, persistent creak. He was lost in the smell of himself, in the comet’s song screaming in his blood, mesmerized by this new animal reality.

A sharp pop snapped his head up.

Then another.

Two black buttons shot across the room, one ricocheting off a bronze brazier with a ping. He grunted, looking down. The top of his garment hung open, revealing a V of heavily muscled, hair-swirled chest. He reached for the next button, his fingers, thicker now, fumbling at the fastening.

He stopped.

A smile spread across his face, slow and terrible. He didn’t undo it. Instead, he pressed the pad of his thumb against the straining button, circling it, feeling the immense pressure building behind it. He looked at the wide gaps, at the raw power of his body peeking through the martial finery now turned into a ludicrous cage. The hunger in his smile widened.

With a growl gathering in his throat, he grabbed the sides of the garment and pulled down, not with careful disrobing, but with a brute downward yank. The fabric resisted for a millisecond, hugging the new, obscene width of his shoulders and back.

He flexed.

A cannonade of pops filled the room as every remaining button surrendered at once, the garment flying open like stage curtains to reveal the whole snarling, heaving spectacle of his torso. Ropes of muscle corded his abdomen. A thatch of dark hair led from his navel down into the tortured waistband of his pants. He shrugged the ruined cloth off his shoulders and let it fall, the motion making the muscles in his arms and chest ripple.

A louder, more tortured creak came from his waist. He looked down at his pants, at the impossible bulge threatening the final button. The hunger on his face shifted into something darker, more possessive. He placed his hands on his hips, fingers splayed over the crests of his iliac bones. He leaned forward slightly, pushing his hips out, presenting the straining bulge to the empty room, to the comet, to the world he would burn.

With a low, grinding grunt of effort, he gave one final, deliberate push.

The last button gave way not with a pop, but with a sharp ping, shooting across the chamber like a bullet. His cock sprang free, monstrously thick and violently erect, freed from the prison of his trousers. It bobbed heavily, already dripping streams of clear pre-cum that soaked into the dark fabric of his undergarments, a stark, undeniable proof of the power that was now wholly, ruinously, his.
