As Extroplan said, it's really a combination of a lot of different cultures/languages. What I've noticed though, is that the BL writers like Kyme typically go through the etymology of a word in like every language and uses that. Like the word Fire, or Hammer, the roman god Vulcan (God of Fire), are really just constantly reused. For example, Mulcebar as he mentioned above, is actually just Mulcibar (spelt somewhat different) which is an alt name to Vulcan.
If you're going to make some extra fluff, this is a great way to make up some names. I've also gone on Google and found a random letter generator, and generated 6 letter words. Put an apostrophe in there and there you go assuming it makes a bit of sense....You'll notice most of the names with apostrophes have only 6 letters, although not sure why.
Edit:
For example here's a list of all the Gods of Fire in every culture. Switch some letters around, add some apostrophe's and you've got Salamander names.
