He’d sold his soul. For that price, he took the same price from others, and he was, in a way, the devils accountant.
He found those with nothing, and raised them, raised them to immortal, untameable beings of darkness, and he loved every moment. He watched in splendour as he took the price for a young man, and he immediately fell to the floor. Xemnas enjoyed being what he was, a reaper of souls, a demon of hell. He grinned, a shit-eating grin that showed of an infinite row of teeth that stretched his mouth outwards akin to a Cheshire cat.
The man on the floor was young, and he had had nothing. His long limbs were splayed out as he could feel something beautiful and powerful oozing out of him. His weary, aching eyes watched the creature over him, watched the tan skin over taut muscles move, the way the demon tranquilly stretched and seemed to breathe in the fumes of life bleeding from his pores.
“Are you scared?” The creature asked, rubbing at his arm, which was decorated with a spiralling, never ending mesh of tribal inking, similar swirling carvings in his skin to the ones on the horns that protruded from his powerful skull. Silver hair framed them perfectly, the flowing spiked water falling low over his back.
The man on the floor shook his head dazedly, sleepily. He had nothing left, and sold his soul for strength, strength to continue after the loss of a loved one, to get his dearest friend back. Xemnas had found him, and offered him the deal. He had had nothing, and so, Saix took the deal.
The soul was leaving him and darkness was bleeding into his vision. A large, strong hand took his collar and lifted him so that he was eye level with the demon. Its eyes were golden, large, and unnerving. They held a look of amusement mixed in with bloodlust and confidence.
“You’ll be a good addition to the devils team.” He almost chuckled. “Pity. A pretty thing like you selling your soul for another. You could have had so much more.”
Saix gasped for breath now, his teeth feeling sharper and longer as they began to snag on his lower lip; he was changing, and he was confused. The demon smiled wilder, and with his free hand, opened up the younger mortal’s collar. He moved his head, his neck, found the thickest, liveliest artery he could, and sunk his front row of teeth into the creamy skin, leaving a half-moon mark describing betrayal and ownership.
The human could barely move; he let out a pained, shocked noise and his legs stiffed and tried to kick, but his strength was sapped away, and his eyes were focuses on the golden harvest-moon eyes of the deadly creature towering over him.
He was dropped, and hit the floor with a near lifeless thud.
“A very good addition. I will be happy to have you serving under me, little human.”
The open gap in his neck was causing the ground beneath him to stain and even more of his energy to deplete. A strike of something akin to lightening struck through him and he jolted, called out in pain, and his elongating fingernails made hollow rivers in the floor.
“Accept the pain, Saix. Become strong.”
His skin turned to shadow and his eyes became brighter, brighter, until they were a solid yellow haze. His hair began pitch black to match his skin, and his soul was no longer his. He was Xemnas’, and he was a shadow. He was no longer himself. He was no longer Saix. He felt almost mindless under a new master’s control, but stronger, with denser muscles. He crawled up onto his belly and lay before the demon. His shoulders were shaking from strain.
“Go on, Saix. Tell me how you feel.”
He creature below him looked up. He was entirely ebony all over, darker than ebony even. He was no longer human. The entire opposite of him. No longer Saix. Anti-Saix.
He opened his mouth, and like his new master had rows of teeth, sharper that needles and craving blood. He let out a howl of anguish.
Xemnas grinned wider.
“Good. Now we understand each other.”
