Cairn was mainly inhabited by the aernar, a peaceful and religious race. However, minotaursstarted taking over the territory, invading from the mainland. Most villages fell under the minotaurs’ aggression. Now, the minotaurs mostly wage war among themselves, on the mainland coast or with other inhabitants of Cairn. One of their enemies are the nomadic Cairn Giants that live in the interior of Cairn.

In the center of Cairn stands Kasdim, an old Chaldean city, full of treasure and valuable artifacts. Today, Kasdim is home to monster factions which battle over control of these treasures.
