The city of Karez was once the crowned jewel in the vast kingdom of King Tyrial, but as he lost grasp on his kingdom, the city fell to ruins at the hands of the dark forces surrounding it. Now the king has died, and his heir, King Tyrial II, has decided to dispatch his finest lords to raise the fallen city and stand ground against all its enemies, within and outside the city walls.

In Fallen City of Karez, each player will take the role of a lord of one of the guilds who seek to tighten their grasp on the rising city. The players will strive to maintain a balance between keeping the city safe for its citizens by sending exploration parties to defeat any threats, and at the same time attracting to the emerging city new adventurers wishing to fill their pockets with fortunes and their names with glory.
