The setting of the game is low fantasy in a medieval world where feudal Empires rule the continents. Magic is scarce and works in subtle ways. The normal inhabitant living in the kingdoms of Khadoria has never seen the art of spell weaving. Only the mightiest of heroes can warp and use the elements beyond normal understanding.

It is a time of turmoil and with the old emperor at the brink of insanity and leaving no heir, all the nobles of the Realm realize that they have a legal claim to the Imperial Throne. Personal power struggles and treason leave everything - the economy, government and social order - in chaos. The goal of Call of the Kings is to win the Imperial Throne, take control of the Empire and hold it successfully against the other players. To accomplish this, each player controls a noble family of heroes and retainers. Players must rebuild the economy, and fund an army, by creating commerce in their towns, establishing trade routes and political alliances, building monopolies and collecting revenues from vassals.

This is an online hybrid strategy roleplaying game set in the Empire of Khadoria, an ancient realm held together by the strong will and political cunning of its Emperor.
