Origins of the base names?

There are a lot of bases in Planetside, and while most of them are pretty self explanatory (Quartz Ridge Camp, Abandoned Mineshaft, etc) the major ones are all named things like Zurvan Amp Station and so forth. A few of the Esamir names are familiar to me (Ymir, Freyr) but a lot of them I don't recognize (Elli, Mani, Eisa, Nott, etc). This question has nothing to do with gameplay, but I'm still very curious to know where these names came from.
