Oh hell no! Use Byzantium as your name and not the official one please. You're tainting the most awesome faction in medieval history with your weaboo residue, go use your historians' name.
Also, steal banner from MTW: II mods much?
Check HRE's full name . IF you're not german, i dare you to pronounce it. And our "weeabo residue" was there and kicking asses when your clan was still wearing diapers, so don't judge =).
As for the banner - we've made about 5 different ones and this one was picked after a short vote. I think MTW 2 mods "stole" the official Byzantium flag in the first place, no ?
