Dead Universe

The Dead Universe is a region in the IDW comics portion of the Generation 1 continuity family

The Dead Universe is a mysterious and malevolent realm that exists beyond the plane of "normal" space. Those who enter are said to become dead in both body and mind and are forced into the service of a vast dark intelligence. A portal between normal space and the Dead Universe exists in the Benzuli Expanse; it was this portal that swallowed up the first Ark mission. This portal is currently expanding and seems on a path to consume the entire local star system. Beneath the surface of Gorlan Prime, a planet in that system, there exists another such portal--this one taking the form of an immense ocean-like body of grey material, through which Dead Universe minions may freely travel.

Characters known to be aligned with the Dead Universe include:
 * Nova Prime
 * Galvatron
 * Thunderwing
 * Nightbeat (subconsciously)
 * Assorted Micromasters
