Really nice article. Great fluff.
This doesn't reflect on the quality at all, but when I came upon Orco the Demon I couldn't stop laughing. I know why you did it, but all I could imagine was a little demon with no face, a robe, a wide brimmed hat, and an O on his chest.

Like I said, I know you did it for IP reasons, it was just amusing. It really was likely the best way to do it and keep the idea of who you were trying to reference.
Brilliant job and I hope to see more. The Raven Que....I mean, the Lady of Crows, is my favorite deity introduced with 4e. You did some justice to her.
