From the campaign:
Players will lead one of the great medieval kingdoms of the thirteenth century by developing an intricate commercial network, advancing its technology, and weaving diplomatic relations with the other players. A number of possible adverse events can occur: natural disasters, and barbarians that will hinder military conquests or the creation of an empire.
The Kickstarter campaign is doing rather well (they're also running on Giochistarter and Spieleschmiede). They're already over their funding goal and working their way through stretch goals. The campaigns are set to run for another 23 days.
