Ok...I know...you said...no orks....BUT....what about...An ork weird boy, called a runt herder. They develop naturally, are willing too, and most commonly do, learn how to speak the languages of other species, and could, potentially, bargain with them. He could of joined Gregori's empire to train his men, as that is a runt herder's job, to train things. With the orks being feral, he could of left, them annoying him with their feral behavior.

I'm perfectly willing to accept no for an answer, but I figure if I don't ask, I won't know, and I do hope that it doesn't aggravate you to much, and if it does, I apologize.
