I must say you did a good job with the translations, I've noticed a few spelling errors and some of it could use a bit of grammatical touch-up (punctuation and word order in some places). Other than that there are some artistic considerations of note, for instance renaming Darks into something else, for instance Darklings, Terrors, Wraiths or something in that manner, and maybe Spiritists into Ritualists or Summoners. Also, I don't know what Zlogns are but it sounds funny and the name doesn't really "roll off the tongue" (like schlong or something).
I'll give it a more thorough look later when I find the time if someone doesn't beat me to it.
