A couple more quick and tiny notes.
-in one of the talks Xan reffers to PC's mother as "biological" mother. While it might be useful in regards to PC's father (Gorion vs Bhaal), I don't think that PC ever had a woman who played a motherly role in his life, so "biological" is an unnecessary anachronism, imo.
-The Sahuagin Priestess reffers to the party as "surfacers". Imo, it sounds too "drow", I think that sahuagn called them differently (hairy, ugly, weak etc)
And for the third one, I am not sure, it might well had been addressed, because I never checked my party after ToB Transfer, but I was wondering what happened to Xan's equipment after he quits at Sul? If he takes it along with him, would you be able to add an option to offer to buy it off him? I know it sort of will break the finale of the game, but it would suck big time to lose all the painstackingly assembled equipment, and on another hand, it also does not make much sense for Xan to go back to Evereska in his skin.
