Eberron: Unsung Heroes
An old thieving friend of Kerra, he sold the woman out and stole her share of the jewels on their last heist. When Kerra returned to Sharn, looking for the man, she found his hideout destroyed and bloody. She tracked him to another tower in a rundown district, with powerful lingering magic in the air.
Raine was found after Kerra hooked up with Verrick and Storme. He was imprisoned in his old hideout by Tannis Sol, and an arcane ritual turned him into a font for arcane power, which he used to try and kill Verrick and Kerra.
Status: Alive. Kerra saved him and brought him back from madness.
