This mod is pretty great! I have 5-6 races near me, and only one is hostile (the things with one eye, one leg and one arm.) The sprites are pretty annoying (on a previous embark, they stole some cloth from a wagon), and the flarestone keeps blowing up and burning my miners. They are getting brown (I think that's bruised) injuries to their upper body; wouldn't you believe that there was a multi-layer vein in my dining room and workshop layers! Its sedimentary, you see; I want hematite, but it looks like I'll have to dig out to the edges of the map.
One of my dogs was killed and another injured in a wolverine fight (the one that was killed was my only male, damn), but the super skilled immigrants that this mod adds were cool... even if one was a High Master... Potash Maker.
