Ahh that makes me feel better about Niita's bio; most of the stuff about Rhelg and the Kressh is fan-written by me. The obscurity and inconsistency surrounding the Sith species does make it hard to rely totally on canon.
He won't be ready for a while, I take a long time to write profiles, and I'm going to commission a picture. As for your blog, I've only really skimmed through but I shall have a better look!
Hey, how did you come up with Sin'ryk's name? Is it a legit Sith name or did you just make it up? I've had a lot of trouble deciding on a surname for Niita, that isn't just off this list.
Both their philosophies had merits and faults. If Sadow had actually succeeded he would have lead the species to even greater glory, but if Kressh had stayed in power they would have eventually stagnated. It was tragic though how Sadow did not in fact succeed, and caused the destruction of the Empire. I like them both, but I prefer Sadow's character :3
