I'm definitely interested! The return of magic is a plot element I'd particularly like to engage with.
I envision a desert mystic type. He was born to a group of people displaced in the Years of Dusk and pushed to the margins. Nomads in some broken part of the world, scavenging to survive. As the flow of magic back into the world turned from a trickle into a torrent, he exhibited prodigious sorcerous talents. Uncontrollable talents. Talents that manifested in disturbing and dangerous ways. He ran out into the desert late one night, and has spent much of the last two years in a fevered, dream-like state, barely conscious, living like an animal in the vast empty dunes under the desert sky, leaving a trail of strangeness in his wake: sand melted into hills of hieroglyphic-etched glass, boulders carved into perfect spheres, ravines shaped so that the wind blowing through whistles in ringing chords.
It was a hell of a bad trip.
But! I don't really want to play a loner. It would be nice to tie his coming to civilization/lucidity to another character -- whether rescued by them, captured by them, nursed back to health, adopted as a student, etc. His goals largely center around learning more about magic, controlling himself, but also feeding his almost compulsive need to act as a conduit for the raw force of magic flowing back into the world. And fending off the madness (risk of possession?) that acting in that way puts him at risk of.
Anyways, that's a first stab at something. Let me know if you have any comments or suggestions, Mr. GM. I'm not super wedded to this, so if it doesn't seem quite right thematically I can try a different concept out on you.
