Sorry for the late reply, it's been a busy weekend. I couldn't get the runnerswift concept to gel in my mind, so I'm shifting my idea around a bit.
It started with a drunken conversation in a bar about monsters. Jeffrey was a writer, always fascinated with horror and slowly making a name for himself in literary circles. The gorgeous young man he'd been talking to seemed amused by his ramblings, but not too amused to turn down Jeff's invitation to his apartment. What happened next...well...he's not sure. One moment he was in the street, laughing and hailing a cab, and the next in the center of a pit of sand with...things...staring down at him. Thousands of them.
Oh, and there was also the monster coming straight for him.
He had no idea how he won the fight. He just remembers staring bewilderedly at the twisted creature in front of him, his clothes drenched in its blood and his own, and strong hands dragging him into the darkness to the sound of cheering. His first victory. The first heart that the young man who he now knew as his master forced down his throat. The first agonizing changes. The first taste of ecstasy that was his reward for amusing the fae.
He had claws for the next fight, ones just like the beast he killed. Each fight brought another heart, another change, another collection of scars, another death. Each change made it easier to fight, and harder to think. Eventually, they didn't have to make the beast eat. Sometimes it didn't even wait until its opponent was dead. The audience liked that. So did his master. Sometimes master even joined the fights himself, the battle becoming a different sport altogether if the beast performed well, or an agonizing torture session if the beast's performance failed to amuse.
But one day, after countless fights, countless victories, the beast that used to be Jeff was pitted against a human. Alone. Helpless. Just like Jeff had been. And it remembered. And it saw itself as it was now, a patchwork monster with nothing human left. And it understood now why it had won his first fight. But instead of throwing himself on the terrified man's makeshift spear as the old beast had done, it ran. It ran until the arena was far behind him, and through the Thorns.
Even after all this time out of his durance, he still isn't good with people. For years, all he knew was the monsters he fought, his master who rewarded and punished him, and the distant, screaming audience. He has to remind himself that someone baring their teeth in a smile is not a threat, and that a growl is never a good idea in a social situation. But he wants to get better, and so he keeps trying. He's still painfully shy at best, preferring to listen and observe rather than talk. Strangers still make him skittish and it takes a lot for him to be able to approach them when he's alone.
His captivity affected far more than just his social skills. Where he used to be eloquent, now he keeps his words simple. He used to enjoy reading, and loved writing more than anything in the world. He can't anymore. He hasn't become less intelligent--far from it--but his ability to sit still and concentrate is all but gone. Stillness was something to be avoided, nothing but an invitation for an ambush. His keen senses do him no favors here either. They were good for sensing danger in Arcadia, but here they grant him a dozen distractions that fracture his attention. It lends him a twitchy, nervous air, and sometimes he needs to be reminded to focus on whatever task is at hand.
He's intensely loyal to those that have shown him kindness, and he goes out of his way to show the same to others. He can be a bit stiff and formal at times, a little too heavy with the pleases and thank yous. It's a ritual for him, something that reminds him he's human. He doesn't like confrontation at all, not even harsh words. He's terrified of losing control, of hurting people, of turning back into the monster he used to be. He still remembers how good it felt to kill, to tear the flesh from weaker monsters, and best of all, how good it was to please his master. He'll back down, he'll walk away, anything to avoid a fight.
