Cube of Power

The Cube of Power is an important quest item in World of Xeen in Heroes of Might and Magic universe. It has many powers, among them the ability to control the direction that Xeen travels in. Sheltem wanted to use the cube to travel back to Terra by directing Xeen through space, a journey that would kill every living thing on it. The dragon pharaoh was unable to face Sheltem as long as the latter had the cube.

After Sheltem's defeat at the hands of Corak, the dragon pharaoh, Kalindra, and Roland used the Cube of Power and the Sceptre of Temporal Distortion to unite the two sides of Xeen, turning the formerly flat world into a round planet.
