The nations in the game are based upon world history and mythology, rather than standard high fantasy races such as elves and orcs. Amongst others, the mythologies of ancient Greece (Arcoscephale), Rome Republic (Ermor), East Rome (Pythium), Sarmatians (Sauromatia), Egypt (C'tis), Medieval France & Spain (Marignon), Medieval England (Man), Ireland (Fomoria, Eriu, Tir na n'Og), Scandinavia (Vanheim, Helheim, Jotunheim, Midgard, Utgard, Nieflheim), Germany (Ulm), China (Tien Chi), Africa (Machaka), Japan (Jomon), Aztecs (Mictlan), Rus' (Bogarus), and India (Kailasa, Lanka, Bandar Log, Patala) are represented. Other nations are based on the work of recent writers, particularly H. P. Lovecraft (R'lyeh), or Abysia, that looks loosely based on Yezidi faith, as it contains Melek Taus in its list of random general names and is mostly associated with holy flames, beings of flame, fire worship and magma, or Hinnom, which is based on Semitic mythology, featuring Nephilim.

We can thank Kristoffers (one of the 2 developers) day job for this. He teaches ReligioMythos. If you go to Kristoffers profile, off to the right is a link for "show all statistics" which will give you a link to "find all posts by Kristoffer O". That would give you a way to track down any others.
