Demons, similar to Devils and Angels are creatures from outside Creation. Unlike devils, demons permanently damage Creation by their very presence. Also unlike devils, there are only 23 different types of demon, each occupying the correspondingly numbered hell. It is important to note that in the Good/Evil duality, Angels are on the side of Good and Devils are standing for Evil, which makes the nature of Demons mysterious. It has been all but stated that goblinfire is at least partially made of Demons.
Known demon types
Madness is one of the most potent demons and leads to a crazed state. When unleashed by Dread Empress Triumphant upon the Callowan capital city of Laure, it killed nine out of ten people and ended the Alban Dynasty.
Known to Praesi as "Beasts of Hierarchy." Not as violent as other classes. Alters the rules of creation. "Beasts of Hierarchy took creational laws, the hierarchy of the world as set by the Gods, and replaced them with something superficially similar but at cross-purposes. Air still existed, yet could not be breathed. Solid was as liquid, friction added where there should be none. Points became fixed without rhyme or reason". (Masego) Wekesa suspected that the Demon of Order unleashed by Akua at Second Liesse was the specimen known as Shango's Doom, responsible for the destruction of the city of the same name.
Apathy causes a slow parasitic corruption in individuals causing their energy to slowly be sucked from their bodies.
Causes mutation and madness in those afflicted by its aura. At the Battle of Marchford, then-Heiress Akua Sahelian unleashed the specimen contained in one of Triumphant's Hell Eggs (a Triumphant-era Legion of Terror standard with a demon bound inside) upon the site. It turned the Silver Spears individually into twisted horrors fused with their armor and horses, while also combining other soldiers and mounts into massive, monstrous amalgams of flesh. This particular specimen has also proved able to corrupt Names if a Name phenomenon is triggered within range. The taint can spread through magical connections and those already corrupted; It however can be contained with adequate sorcery. Demons of Corruption originate from the 13th Hell.
Possesses the ability to remove knowledge of people, places, and events from Creation. Direct combat capabilities unknown. Possibly responsible for the disappearance of the Yan Tei empire from Callowan history books for several centuries. Potentially responsible for the erasure of part of a Hell and the two decades during which the three Secret Wars were waged between Praes and the Kingdom of the Dead.
- A Hell Egg containing an absence demon was suspected to reside near Harrow. Possibly unleashed and killed by the Crusader heroes, as a few days after the Grey Pilgrim pledged to kill the demon, Catherine Foundling experienced headaches and spoke of there being 12 crusading heroes when there were originally 14.
This type of demon causes those it touches to experience permanent intense fear. It develops through three stages (Anxiety, which can be cured altogether with heroic intervention and medicine; Dread, which cannot be cured but can be mitigated; finally Terror, which cannot be either cured or mitigated). This type of Demon is known to Procerans as "Dreadfiends".
Demons can be bound if a mage is proficient enough in the use of wards, as well as their own control of magic. The Dread Empress Triumphant was known to have bound demons to her standards, allowing her to unleash them at a moments notice. Although this was an ability which she took with her to the grave, there still are a few of her standards (known as Hell Eggs) hidden throughout Calernia.
Bringing a demon into Creation is difficult enough, but ensnaring them to your will is akin to putting a straw leash on a raging tiger. The demon will constantly fight to usurp control and turn on their master. A Name such as Diabolist, would allow a being to control multiple demons, as well as properly direct them at their enemies. Still the snare that is used to bind demons is made of sorcery, thus it can be usurped by another mage and severed unleashing the demon.
