Yeah, I got a little carried away writing the description, first from sheer enthusiasm, and then on purpose since I happen to like Ka-ha-si's story, and it's a real story that I tweaked just a bit to make it fit Atlantis, and extended quite a lot from the bare-bones I got in Wiki, but didn't deviate from. I just honestly felt like, since Dom3 has so much mythology in it already, that it'd be nice to give you all an actual myth, in the form of a story, the same way it would have been passed down centuries ago. It's one I read when I was very young, and rediscovered while researching Inuit mythology on Wiki. So, for the hero's description in-game, definitely check out Wikipedia, under Inuit mythology, "Ka-ha-si", their stub will fit perfectly. I'd rather not reproduce it here, word for word, for the sake of avoiding copyright infringement
but if you change a few words here and there, you'll be all set. Sedna's there too. I don't know what to do about the unique names problem, but there must be a modding solution, if not now then hopefully forthcoming. After all, names have power.
