Nigon is the second underground race.

*offtopic, just to clarify* There won't be any Baba Yagas or immortal Koscheis there; they are completely unnecessary in Ashan. I have some other ideas, but the Snake will definitely be a level 7 creature, just not a three-headed dragon. By the way, I've already come up with an ability for the faction, but the units don't have parameters or abilities yet. Anyway, as soon as I get it into a somewhat decent state, I'll post it. And these won't be Slavs, but rather based on Slavic motifs – do you feel the difference? ;)
I'll come up with designs for the monsters. I'll post them when I've drawn them.
