Yeah. That and to me, it just sounds like "moribund", which...I guess might be appropriate for a Sith world considering the death connotation, but it doesn't really have the same ring as "Korriban". "Moriband" just sort of sounds like something I would have made up when I was a kid when I was looking for good villain names for my stories.

Maybe I'm just taking this too seriously, but...it's just unnecessary. (Then again, I guess that applies to most retcons, really)
