Champions of the Titan's Eye
A burly human, burdened by guilt in two lives.
In Harrod’s mortal life he abandoned his wife, child, and paladin’s duties, running away to the first ship available. Unfortunately this was a slaving pirate ship, but he wasn’t asking many questions at the time.
Once the heroes arrived, Harrod recognized them as angels, and remembered his own angelic past. This past was also was filled with guilt and failure, as Harrod the Angel had witnessed the corrupted angels attack (and be destroyed by) the heroes but did not speak out.
