I think you posted this in the wrong forum - we have a place dedicated to fluff. It's called the fluff and fiction forum
.
However, I suppose that place is pretty useless after it was flooded by 'Online Campaigns'.
Well, I could type out a bunch for you, but I'll mostly just give you this link.
http://www.40kcantina.com/eldar/encyclopedia/encyclopedia.htmlAnd for other names, take actual eldar words (
http://homepages.ed.ac.uk/daviddo/ELDAR/English-Eldar.html) to describe the character, then crush them into one short, single word.
ie
Destiny Warrior (names are normally MUCH more words, but for ease's sake (these words aren't really well-suited, either))
Furte Ann
Which could be compacted into Furan, for example. Go and Look at the page in Codex: Eldar right near the end, which gives a good description of the Eldar language, and an example of a name.
