Hello! I'm the player DM Lament Configuration was referring to. First things first, let me say I considered receiving DM Lament Configuration's invite a pleasure, and doubly so once I quickly perused through this thread and saw all the great submissions he got. So - nice to be one of you!
As for the PC, I first considered rolling some kind of party face, but eventually realized Lovecraft's mythos isn't exactly choke-full of people being nice to would lead anywhere, so I'm now considering an Inquisitor of Desna (or of the Black Butterfly, which would more or less be the same thing, both mechanics- and flavor-wise) with the Void domain. Of course, I'm open to suggestions, especially when teamwork feats are concerned.
