Absolutely fascinating. I've not yet participated in a Play by Post campaign; I've written cooperative stories online, but that's about it. Gothic horror is a genre that I've always loved, however. I've a few too many voices clamoring for attention in the chaos of my mind to fully ascribe to one yet, but the loudest ideas thus far would be either a changeling sorceress or possibly, an occultist of race yet to be determined. If you're not opposed to having a player that's new to PbP format--though new neither to Pathfinder nor writing!--I am intensely interested in this idea. I'll try to get a fully realized character together if I ever get home from work this evening.
