how is that different from dealing with a king or a dictator in BM. your only dealing with a single person the only difference is that a human character has many nobles to carry out his/her threats or orders.
Treat the zuma like you would any other realm. you just have to talk to them on their terms.
Except the Zuma have zero internal conflicts, zero room for error in fighting wars, single units with 10,000 CS, no chance for a change of rulership, no religion, no political division, and complete unity of their forces and can declare war willy nilly with practically zero political ramifications.
These are major differences from a human realm that majorly alter the game.
