Ha -- the Essek currently floating about Exandria doesn't know what he's missing out on when it comes to such collaborating, truly. But the sentiment is returned, I assure you; I'm glad to be able to call you a friend, Gilmore.
Ah, intriguing. If information is what you're after, that is something I can help with. A few books come to mind, so let me pull them for you and I'll check if I have anything else that might help. I think only one or two might be in Undercommon, since deities tend to be fairly straightforward for drow, depending on where one lives.
