Perhaps one of the greatest mysteries that has entered our world exists in the Creep. A gelatinous, living substance like slime, the Creep is an unnatural thing that devours all life it touches. The Creep can only exist in shadow and generally makes its home in dark places, spreading outward. Anything caught in its grasp will be engulfed at a rapid rate. Due to its inability to be understood, it is likely an entity demonic in some fashion, perhaps related to the sins of Gluttony, or conversely Famine, or even Madness.
Much of this article is from Caudex Daemonum, by Grigore Summers, including his speculation on its potentially demonic nature.
Appearance and Behavior
The Creep has been described as a sickly grey-purple in hue, or grey if it has entered a dormant state, during which it becomes like stone. In this shape it conceals itself until something alive touches it. Then it will immediately awaken to devour life again. In its bid to absorb all living things, the Creep can extend tendrils from its mass to snatch its prey. Some mages say the Creep is the sweetest substance known to man, and if one were to eat it, one would experience bliss almost alike to eating ambrosia, the food of the gods, just before one’s mind becomes consumed by the creature.
Smaller, mobile beings exist separate from the Creep, called Creeplings. These creatures are the result of living things that have been touched by the Creep. As the Creep digests the form of the living creature, it may possess it, using that creature’s body to move about. However, as the prey is digested over time, it will become misshapen until it returns to the same formless slime as the rest of the Creep.
Masses of Creep have been discovered only in the most secluded of regions. It is thought to have originated from the Blasted Wastes far beyond the southern lands, where it was created, or perhaps summoned, due to the Mage Wars of Sinkarya. The Wastes remain its greatest home in this realm.
This entry on the Creep comprises one of Summers’ best descriptions of an unnatural or monstrous creature. So little is known of the Creep that his writings can scarcely be offered addition.
Dear reader, should you have the great misfortune of encountering any Creep or especially Creeplings, do your best to avoid it entirely. Anything it touches will become tightly lodged and drawn into its mass to be devoured and possessed. Physical attacks are all but useless against this abomination, though some Venatori report severing the limbs of Creeplings still with form enough to have limbs. Even this still could not stop their advance, but it at least slowed them enough to provide escape. As with most any monster, only the Venatori have even a chance of battling, much less truly destroying, any form of Creep.
We are incredibly lucky that the Creep has spread so little in the mortal realm and that the holy light of the sun, and even the moon, can usually keep it at bay and prevent it from engulfing all life.
