Imperial symbol of Terra Magnus.

Terra Magnus is a alternate reality set within the Landmark Universe. A violent, warlike empire ruled by malevolent transhumans, Terra Magnus is the "dark twin" of the Planet Earth, a hellish dominion bent on universal conquest. In recent years, the Terran Imperium has developed trans-dimensional technologies, allowing them to access a number of "Quantum Universes" including our own. Plans are currently underway for a full-scale invasion of Earth Prime, using Chamberlain City as the primary spearhead.
