A social survival sandbox game set in the world of Ultracore, the game combines three major pillars: a survival sandbox (the world of Tormentosia), a social hub (Coreheim, the location of the Ultracore) and adventures (diverse action experiences).

Tormentosia is the name for the land encompassing all known realms. Once, it comprised 36 empires with dozens of diverse races. After the attack of Sorgoth, Devourer of Worlds—and the following war—most of these nations fell victim to devastation. Their inhabitants who survived the bloodshed, fled to the lands yet unfallen. These remaining seven realms—now including the newly formed, joint nation of Coreheim—are as diverse in their flora and fauna as can be imagined. Coreheim lies in the center and houses the Ultracore. Its shield protects the last seven realms from sharing the fate of other nations of Tormentosia at the hand of Sorgoth.
