Unholy Empire
The Unholy Empire is what Mortismere called his rule. It was not a faction. It first began when Mortismere ascended as a demonic God in Kali-Sheol. But his lust for power was not quenched.
On Earth he forged the Empire with Charon Death. However, the Empire crumbled after his attempts to create the perfect being Anexous failed.
However, in Mortismere's portion of Hell his vast Unholy Empire grew at a tremendous rate. It came to a climax when Mortismere actually challenged Dalkiel for control over hell itself. Mortismere's forces failed especially after an attempt to use Violent Josh? as a vessel into the realm of Earth.
Today, Mortismere's Unholy Empire still rules over Kali-Sheol and his 'darkside elites' called Caput Mortem?s carry out all of Mortismere's commands even on Earth. The Empire's central command is a flesh and bone made Cidadel deep within Kali-Sheol... where Mortismere sits on a corpse-made throne.
