Nice, Hairy.

Now, I was thinking about the whole Rashemi berserker concept, particularly inspired by characters such as Minsc from the Baldur's Gate game series and Fyodor from the Starlight & Shadows book series. Will I find sufficient info on the whole berserker thing (lodges, rage, etc.) in Unapproachable East?

Overall, I was looking into giving some BG NPCs some 3.5 stats, particularly Minsc. Of course, that may not be until I've finished the DCI character stats. Speaking of which, I'm going to need Kayless' input to do much of anything else w/ that.
