Imperial is obviously greco-roman
This one depends. There are a lot of names that are baiscally Latin or fake Latin, but there are also names that are just the random whatever-the-dev-liked kind. You see them in Oblivion a lot. I sort of assumed that Latin was Nibenese style and the randoms were Colovian.
Eddie Theman and Jim Stacey.
I think Fast Eddie is just Edd Theman. 'Edd' is still a little weird for a Dunmer name but not that weird.
Gentleman Jim Stacey is more complex. First off, he is a Redguard, not a Dunmer.
In the CS he is just called 'Stacey' which is a very typical Redguard name. My assumption is that 'Gentlemen Jim' is a nickname/alias from his Thieves Guild life.
Dunmer names come in three basic forms:
- Housemer, aka 'Settled Peoples'. Names like Draren Thelas, Nels Uvenim, etc. They do have a distinct feel and you'll find some letters, like C, K, W, Z, etc, very rarely show up. There's a list on the IL if you want to compare 'em.
- Ashlanders and the Velothi (the semi-settled Dunmer like in Gnisis) use the same jaw-cracking style you see in Daedric Ruin names. It's based loosely on Assyrian.
- Some rare Dunmer have one-word names that are very similar to Bosmer names. I have no idea why. Perhaps they are exiles, have renounced their family, adhere to some old Chimer practice, who knows. They appear in both Morrowind and Obivion.
It was mentioned above that House Dunmer use [Family name] [First name] form. I think this is an archaic thing. It's rarely seen in-game, even among all those Hlaalu family characters (King Hlaalu Helseth being a notable exception, and one that I think supports the idea it's an archaic, formal styling). In addition, Ancestral tombs match up with the second of NPC's two names, not first ones.
