I cannot speak for LJ either but being the guy who developed and wrote out the Omestri race and Inquisitor training (with Scout and another long lost member) with LJ's guidance I would say that a lone Omestri killing any Inquisitors is a bit much-ish. I understand the trope of the hidden power of the Fire Titan and the flair in the character background but I think the Omestri are less of the noble slave trope and more of a "Reek" from GoT honestly. At least that's how I always saw them, I mean these people have been culturally destroyed over generations and reduced to a commodity, utterly vilified and ground into little more than dirt or oil to be used up for heat. 

I am not trying to be a bummer Arch, I would love to see you join up after LJ gives you the thumbs up, I just want you to have the best character you can have that falls in-line with all the stuff that has already been laid down over this long span of time. All the other stuff seems great its just that bit that doesn't fit, I mean its like saying a beaten and tortured house slave defeated 2 or 3 Marines or MMA fighters.
