Living Apocalypse

The horrific creature known as a living apocalypse is created when the most powerful destructive energies known to the galaxy are unleashed without constraint or limitation, especially in acts of malice or as a result of criminal negligence. A living apocalypse can be the result of powerful energy generators melting down, the use of doomsday weapons, or even magic experimentation gone horribly awry. The creature is driven by an instinctive need to destroy, and it often takes the form of a massive cloud of impenetrable oily smoke, lit from within by pulsing bolts of green radioactive discharge. A living apocalypse is drawn to high concentrations of life and complex structures, from vibrant rainforests to bustling cities, and attacks them without warning or remorse. Though mindless, a living apocalypse is driven by a supernatural force of anarchic evil to enact ruin. It has been suggested that a living apocalypse is an agent of the Devourer, but even if this is true, Devourer cultists are incapable of intentionally creating or controlling them. Some lifeless worlds are the burned-out remains of civilizations that created a living apocalypse and were totally destroyed by it.
As a creature that is infused with incredible destructive energies, a living apocalypse commands energy rays of pure radioactive force and powerful magic abilities it can employ with instinctual cunning. Though it is unable to form complex plans or comprehend complex chains of cause and effect, a living apocalypse is able to apply its ability to manipulate energy to deal with immediate threats with what seem like carefully considered tactics. Once a living apocalypse is unleashed in a region, it destroys everything in its path until there is not a complex structure or significant life-form left within hundreds of miles. Because it is mindless, the ooze follows a path dictated by what it can sense at any given moment. If it can’t detect anything nearby, it settles in one place, using its broadcast ability both to listen for wireless signals and to send signals out in the hopes of drawing in more victims.
When there is nothing left to destroy and no change for centuries, a living apocalypse eventually goes into a dormant state, often at the bottom of a chasm or within the stormiest region of a world, waiting for centuries for someone to find it. A typical living apocalypse is 30 feet in diameter and weighs 187 tons.
