*~*~*~*~*~*~*~*~*~*~*~

Strong hands awash in an angelic glow were raised before a face. Eyes wide, lips open wide to scream, the angel was bested. Robes torn and bloody as white feathers danced in the air.

"P-Please, brother..." he begged, his voice cracking as rose-pink blood bubbled and spilled down the side.

The one who looked down upon him laughed, the sound dark and reverberating in the air. His wings flared out, slowly turning from their pristine white to pitch black. Black like the act he would commit.

Sword ran through the bloody angel on the ground, the blade feeling little resistance as it tore through flesh, muscle and sinew.

His fingers grasped the chin of the one he killed, and he watched how the light faded from sky blue eyes. A bloody hand over his, "n-never love in," he coughed up more blood, spraying it all over his bare arm, "your heart. I-I curse thee heartless..." The angel died.

Sebastian woke up with a jolt, his breathing was rapid fire as a bead of sweat traced down his face. He closed his eyes and tried to steady himself in the large bed. He swallowed air as he reached over for the black and gold pitcher of water, trying to get something down his burning throat.

He drank from the pitcher, not caring to use a glass, as he processed the moment. It wasn't a dream; it was a long almost forgotten memory. Almost forgotten because he saw it again right before every Mating Season. A curse from one of his previous brethren had haunted him for millennia.

Sebastian put the pitcher back, now that it was empty, and he sat against the black feather pillows. He pushed his black sweat damp hair from his forehead and gathered his mind. For once he hoped...

The door creaked open and he knew he failed. He shouted and when he did, only one demon would ever hear him. His twin sister and Prince of Nine, Leviathan or Leia as he called her.

She walked into the room, her pale feet barely making a sound on the black marble. He looked at her, long black hair braided for sleep, eyes the same red as his, long black claws for nails and a lithe figure.

"Asmodai, are you alright?" she asked as she took a seat at the edge of the red silk bed.

He considered telling her, he was fine, but she was the one demon he would never lie to. Not because she was his twin but because she was the Prince of Lies.

To be considered a Prince the demon had to show an uncanny strength in an ability. To prove this each Prince had to undergo three years of trials and then they were judged by Lucifer to be one of the Nine. The original Princes were all fallen angels, having been beside Lucifer when they went to war for free will. Only three of them remained, the other six were from different demon lines.

Sebastian shook his head, "the memory."

His sister sighed and pinched her pale forehead, "like clockwork. Before every overlapped Memory Season."
