I'm probably the only one that cares, but the mod finally spells Aŋra correctly. Alikalix provided an entirely new bitmapped font set that adds the special character and many others.
For any linguists out there, the mod derives names and words mostly from Old Norse (somewhat anglicized but much less so than Tolkien did) and Old Gaelic. These are primarily but not strictly associated with Man and Sídhe, respectively. They look kind of similar with the accents but are very different in letter use. (I did convert Ðð and Þþ since most English speakers can't even guess their sound.)
However, a few things in the mod come from other places, including desert gods and the theistic religions, since the Norse and Celts didn't have either of these. You'll see some new pantheistic gods in phase 3 associated with the desert, Abgal, Nergal, Nesr and Wadd, derived from pre-Islamic Arabia or related sources. On the theistic side, Aŋra is the best representation (in our character set) for a word meaning destruction in Avesta, which is the original language of Zoroastrian scripture. Aŋra Mainiiu (=destructive spirit) was later transformed into Ahriman in Middle Persian. The Wiki has Azzandara as an alternate name for Ahura Mazda (~light/wisdom), Aramazd, Ohrmazd, Hurmuz, etc., although I haven't been able to track down the exact specific source for "Azzandara" yet. Hard to figure this out when 100 different web hits are all just copied from an older wiki page.
Perhaps I'm crazy to do this, but it's fun doing the research. The sound and look of the words give them a specific feel. For example, it seems to me that Nergal, Nesr and Wadd just have to be associated with the desert. It's also fun discovering the original source material used by Kael, Tolkien, Lovecraft, Howard and others.
