I'll come up with a name.  Fuck it.  Tyrix Okobados.

I actually had it as Orkish as that's the way I prefer it but I was thinking that's the Fantasy spelling rather than the 40K spelling.  Got it back asswards.

My concept for him is basically someone slowly turning toward Chaos for mostly good reasons.  Probably Tzeentch as he's planning how to do things differently to spare needless deaths, get better results, and maybe get remembered in the history books.
