Remember Seth?

"Hello, Logan."
The young prince would look up quickly, turning around to try and see where the voice had come from. His eyes would focus on a dark corner of his chambers. From the shadows, a boy of about sixteen would step forward. His skin seemed as pale as moonlight, and his hair, which hung down over his face, gave a stark contrast of jet black.
"Wh-who are you?" he stuttered as he stumbled back.
"I hear you've grown quite fond of Rhiannon." The boy continued forward, his boots silent on the stone floor, cape draped over his left shoulder, a trick often used in those times to hide one's sword.
"Rh-Rhiannon? Are..are you a friend of Rhia's..?" The prince's heart began to pound as his step was halted by one of his bedposts. This boy had to be younger than himself. He was a bit shorter, too. Why was he so terrified? Was it because he'd gotten in without alerting any of the guards? Or was it something...else.
"Friend? Sometimes..." The boy's step didn't slow as he approached Logan, and as he came closer, the light would reach his eyes. And those eyes would give Logan a real reason to tremble. They weren't the mysterious red that had caught Logan's eye about Rhia, but rather a dangerous crystal blue. A blue that held secrets, and hatred. The boy finally came to a stop uncomfortably close to Logan, looking him dead in the eye.
"Wh-what is it you want?"
"I want..." The boy's right hand lifted, though he would stop when he saw the glove. An amused look would come into his eye as he lifted the hand, taking one of the fingertips of the glove in his teeth and delicately pull it off. The skin of his hand was just as pale and disturbing as his face. He took the extra time to slip the glove into his pocket, all the while making the poor prince squirm. As the boy looked back up at Logan, he would speak in a casual, airy tone. "Now, where was I? Oh, yes..." His voice dropped back down to that rather sultry tone, "I want..." His hand would lift again, only this time, ice cold fingertips would touch Logan's face.
The prince would freeze up, breath caught in his throat as he stared with wide eyes at the boy. He tried to press himself further back into the bedpost as the boy stepped even closer to him, one foot sliding between his.
"..you..." His face came awfully close to Logan's, the prince able to feel his breath on his lips. His breath smelled like death - and not just in a rank way, but actual death, as though he lived, breathed, and spoke it - and it made Logan's stomach turn.
As the boy pressed up against him, Logan would suddenly feel something sharp press against his stomach. It caused him to shudder and tilt his head to look down. A cruel-looking knife would be pressed against his stomach, the tip just breaking the skin through his shirt.
The boy's lips would come up against Logan's ear, whispering, though the message rang through loud and clear.
"..to stay away from my mother."
With that, and a cold gust of wind that came in through the window, the mysterious boy would be gone.
