I was thinking of a mod where the Calradian Empire was being its rise to power. As the Calradian are the mount and blade versions of the Romans I guess there is going to a Gaulish based faction, a Carthaginian based faction (War Elephants), A Macedonian Greek based faction, A Ptolemaic Egyptian based faction (unfortunately the units will be nearly identical with the Greeks) and a faction based on the Parthian Persian empire (which for sake of continuity with Mount and Blade Warband I will call them the Sarradians)
