Piers told lots of different stories about where he came from, but he was, in fact, born a light elf. He never felt at home, never felt welcome, and certainly never felt at peace with himself. Having grown majorly pissed off with his family's bigotry and rancour about other races, when his opportunity came, Piers buggered off. This opportunity was when the races melted. His family reassumed their position as light elves, and Piers, thumbing his nose, spurned his heritage and remained a true elf. He thought the expunging of magic from himself would make the strange creepy "This isn't my skin" feeling go away. It didn't.
So we ran off and went to live in a wood. Having lived in the woods of South Cymru for a good while with a friendly werewolf, he decided that the woods weren't for him either (no mirrors, oh my goodness me!) and came to Grantabrugge, and began a life of shaggery and excellence.
The crawly feeling remained. He tried to drown out the crawly, creepy "Not my skin" with prostitution, which he enjoyed, and supported himself well enough on. It didn't go away through that, either. So, Piers flirted briefly with religion, following Luca's guidance as a lay follower for a few months, hoping that would fulfill him. It didn't.
So he went back to being filled, and thought very hard. His life was boring him. He didn't have any emotional attachments beyond friendship with only a precious few people (he could count the people he genuinely cared about on the hand that was missing a finger) and was getting fed up of being the passing toy of rich perverts. He had almost given up and started to wonder what would happen if he offered to be a test subject for Horace Wainscot's "Bedtime Drinks", when he met Crimson.
Aha.
He'd seen Fae before, but they were... aloof. They'd never connected with him, visa versa. But Crimson was different, straight-forward, cunning, and intriguing. Through Crimson, Piers met other Fae like him. Unseelie Fae; polite, gritty and with a heartfelt code of honour and playfulness.
Piers's little brian-cogs began to clank into action. How on earth could he become one of those? He's changed race once, but that was accident. How could you change your race permenantly and purposefully? Over the course of about a year, some purposeful toil, some happy accident, Piers got where he wanted to be.
He's now a Fae. A real one. And that itchy-skin feeling's gone away.
And he lived happily ever after.
The End.
