Who is Kitava? Is that what the Karui call Dominus?

A name mentioned by Haku. Google can't find any occurrence of the word on any PoE related site. Since Haku mentions "Kitava's tyranny" I can only assume he's referring to Dominus...I mean, he would have said more about this Kitava if it were a NEW enemy, right?

Ah, got further in the Haku dialog and he clarifies that Kitava is the "Black Spirit" mentioned in the carvings.

well on some league of legends video. Kitava is the father of cooruption. aka the bringer of all that is corrupted and 'kitava' seeks to corrupt all that is in wraeclast, etc
