I was reading an Inklesspen review of an ancient DnD? sourcebook, one focused on making dragons playable, and had the itch to make a character for it. I basically designed his and Dimitri's initial concept from poorly-remembered overarching concepts from that book, and, uh, rereading it proved that my memory had been very poor indeed. :V So I ended up just taking the differences and running with them, making it into an entire setting of its own.
(most of my oldest OCs i unfortunately do not remember how they were conceptualized very well...)
