Heh, tried to take a screenshot of the Friendly Arm inn in my game, but for some reason i cant, suffice to say that i collected every NPC (including mods) with the exception of 2 dudes (dragonslayer paladin & the guy that goes with you to the Vampire keep, both in DSotSC) and now there is a huge crowd of people at the entrance to the inn . An heaven for NPCs in BG2 not only would be a awesome idea, but it would be MUCH appreciated.
Well, as for what kamuzin said about vampires, the same could be applied to the Drow, yet we have sexy drow priestess that can change her ways and in the end, love "Charname". Really, this is a mod, everything is possible and dont forget, we are talking about D&D vampires here, not your average "traditional" vampire.
As for Anomen being corrupt, kamuzin, your trying to apply real world logic to D&D universe, paladin's are hardly corruptible, only some drastic event could change that, and i agree that even if something would happen, he would have to stay Lawful.
