Zepath, seeing how you are making such nice mods I thought maybe I'll throw something your way in the hopes that it kindles your interest
There are two things I really would have like to see a mod for.
The first is the drow, aka dark elves. At least the way they are described by RA salvatore or maybe the similar to their representation in masters of magic.
The second could be a huge undertaking and probably not feasible but I'll say it anyway. It is a mod that reflects the noble houses of George Martine's song of ice and fire.
