Tumanbay: the most magnificent city on earth. The beating heart of a vast empire. A city of dreams — where those who arrived as slaves now reside in the seat of power.

But the wheel of fate is never still: from the gilded rooftops to the dark catacombs, there are secrets waiting to be uncovered.

And a mysterious stranger arrives with a gift for the Sultan himself.

A gift that will change Tumanbay forever...
