I would agree with John Thazer on that, the stonebreakers are kinda gnomish, and (no offence intended, apologies) the dwarf women look really gnomish.
Ah yes, Avernum. I spent hours playing that, then I found Planeshift and well, now I haven\'t touched Avernum in over six months. Hm. Yeah, I know, I\'m a geek.
I would also consider Klyros to be closest to amphibians, but close enough to be your \"lizard\" race COLDBLOOD. We are the coolest of course (except for lemurs perhaps).
