Icaion is an Engine Territory Building, Resource Management eurogame designed by Martino Chiacchiera and Marta Ciaccasassi.

The game is set in the regions around the giant crystal on the surface of Icaion, the planet below the clouds from which the floating islands of Mysthea detached millennia ago.

In Icaion you become a Seeker, an expert adventurer, sent out by the Organization to hunt for treasures, Qoam, relics and artifacts from ancient times. Beware, in the farthest lands from the City a titanic being lurks, moving relentlessly while spreading an illness all over the world. This Colossus has been a mystery for the people of Icaion and you will inevitably cross its path.
