Overlord Demons

A race of demons specifically bred by the higher Demon lords to act as lower level captains, slave masters, or work bosses. They are sufficiently intelligent enough to boss around those lower than themselves, but lack the will to make important decisions. They are bred for their size and strength, and tend to rely on brute force in any situation.

Argat Bat Mahlat

Agrat Bat Mahlat is one of the four angels of prostitution, and one of the wives of the Archangel Samael, along with Lilith, Naamah, and Eisheth Zenunim.

Malproditix, the Betrayers

The Malproditix are a type of demons who were originally the darkest of souls. Only the most willingly vile and destitute during life have the chance to join their ranks. They are called "The Betrayers" as they have turned their backs utterly against mankind and all that is good and pure for a pittance in Hell. Their bodies are permanently twisted and pierced. As each of their movements sends them into unknowable agony, and their only release comes from inflicting the same on others. Although they have earned somewhat of a position of respect in the lower demon hierarchies, most Demon Majors treat them little better than cannon fodder. During the many wars in Hell they are often sacrificed first.

Dominatorite

Dominatorites are animate, mindless killing machines used as shock troops and assassins by greater demon lords. The creatures are barley sentient, able to only obey the most simple of commands. They must be continuously fed, as if they are allowed to lapse into hunger for too long the will eventually go berserk and attack anything within reach.

Sonneillon, Lord of Hate

Sonneillon is the demon of hate, formerly of the order of thrones, and the adversary of St. Stephen. He tempts men with hatred against their enemies.

Yblicharix

Yblicharix are a race of demonic worms, which burrow through the fleshy ground in Hell's lower levels. Although originally not demons themselves, eons upon eons of exposure to dark energies has warped them in ways which cannot be undone. Many of them have begun harvesting souls and graduated into true demonic status.

Belial, Crown Prince of Hell

Belial is one of the four crown prices of Hell. He commands over fifty Legions of demons. He bestows honor, titles, and royalty, if the proper sacrifice is made. He seduces the weak by means of arrogance and pride.

Arathorachrix

The Arathorachrix are hellish scorpions, created by combining particularly egregious souls who's sin is betrayal. As they have squandered the trust of those in life, thus will they forever sting those in the inferno. The Arathorachrix are often kept as instruments of torture.

Oeillet, prince of Temptation

Oeillet is a prince in the hierarchy of hell told to Soeur Madeleine de Demandoix in the early 17th century by the demon Baalberith. He is Prince of the Archangels, tempts men with cruelty and mercilessness toward the poor. He enjoys tempting men of the cloth away from their vows.

Adepts

Adepts are exceptionally gifted demons minor who study the dark arts with fanaticism. They are often kept on retainer by the higher demon lords, and act as sargents, lieutenants, spellcasters, and majordomos. It is not unheard of for a particularly crafty adept to manipulate events and elevate themselves to Demon Major status.

HellRats

Infernal rodents, twisted and mutated through millions of years of exposure to dark magics and evil energy. HellRats swarm by the millions through the infernal cities, dungeons, and palaces in all levels of Hell, living off the detritus, waste, and carnage. They have been known to swarm and devour any stray demon or soul who ventures too far into the myrid tunnels or catacombs without adequate protection. They are a primary food source for most demons and souls, although most just exterminate them as vermin.

Carrion Slug

Carrion Slug are among the small group of rare mollusks to inhabit Hell. As the infernal planes are nearly devoid of water, the slugs have taken to using other liquids to obtain moisture. The creatures will slowly swarm on a sleeping demon or soul and rapidly drain it of all blood, leaving a withered husk in the morning. They are generally regarded as pests and are exterminated on sight, although several demon species enjoy feasting upon them, usually raw.

Infernal Locusts

A species of large, carnivorous insect which infest the multiple battlefields in Hell. After major battles they often swarm to feed upon the carnage, afterwhich they usually must be culled to keep them under control. Most demons actually consider the hellish insects to be a rare delicacy.

In the book of Revelations the swarm is released upon mankind under the command of Abbadon, lord of the pit.

Ichixidea

Ichixideas (otherwise known as "Blood ticks") are common parasites which infest all levels of Hell. Blood ticks range in size from a few millimeters to the size of a grapefruit after feeding. Ichixideas use their powerful back legs to latch onto prey in a grip which makes them virtually unremoveable.

Like all of Hells' "wildlife," Ichixideas are often distorted and mutated due to the conflux of dark magics and demonic energies.

Orobas, great prince of Hell

Orobas is a great prince of Hell, with twenty legions of demons under his control. He will impart truthful knowledge when invoked, and is the benefactor of conjurers and sorcerers.

Amon, Marquis of Hell

Tuqahocuilit, the burrowers

The Tuqahocuilit are large, worm-like demons that burrow through the stony, fleshy ground between Hell's many levels. As such they are in a unique position, and are one of the few demon races to move freely between the planes. They hold loyalty to no single demon lord, and often delight in playing them off against each other. They have been known to grant access through their territory for demon and soul alike, but will always exact a heavy toll.

Vorisquillade

Vorisquillade demons act as living garbage disposals, utilized by higher demon lords to periodically sweep through the twisting cities and dark corridors to remove the random remains and detritus that often accumulate in such places. Vorisquillade can use their shifting anatomy to form multiple mouth orifices. The creatures tend to breed rapidly, especially when large food sources are available (such as after a recent battle,) and need to be exterminated from time to time.

Abyzou, Slayer of Children

The Abyzou is a female demon in the folklore of the middle east. She is blamed for miscarriages and sudden infant death syndrome. In the Testament of Solomon she is described as is described as having a “greenish gleaming face with dishevelled serpent-like hair," and that she wanders the Earth looking to strangle newborns.

The Abyzou was often depicted on magical amulets, designed to ward her away from newborns.
