[@Aristo]

Character centric. You'll assume the character of a noble or someone in a position of power. The pre-established realms are really just placeholders. Things can be molded to individual player preferences within reason. But for ease a player may just take one of those realms and customize them heavily to their own imagination. Like take the Empire of Kali for example. You can assume the role of the Emperor/Empress. But the exact culture of Kali, its society, and even history are up to the player. Think of them more as placeholders to get an idea of how the Geo-politics will play out. 

There is a loose plot. But it's more like a sequence of events that players can react too and potentially change the balance of power.

In terms of goal: Acquire more power. The end game is basically who can unite the continent and how.
