Hi, is there room for 1 more?

I have an idea for a character. He will be a tribal leader of a beastkin tribe. Born in a tribe near the border with the marches, my character was given as hostige to one of the vassals of Justinian in exchange for peace between the tribe and the warlords of the empire. He eventually returns to his tribe and kills the chieftan. Now he's in the process of unifying as many tribes as possible under his banner of flame and ash.
