One of Hell's many city states, located on the southern coast of Aporue, one of the more populated continents on the eastern side of the Boiling Sea.  

With a direct line to Earth via the Paris Catacombs, Brimstone's growth has been heavily influenced by human factors, whether the townsfolk are aware of this or not.  The architecture ranges from Gothic and medieval, to Greek and Roman styles, and to the outside observer the entire town seems like a hodgepodge of mismatched buildings.

Though close to the ocean, Brimstone doesn't have much of a seafaring tradition; instead relying upon its history of academical exports, such as books, tomes and scrolls.  Many bookbinders and scribes once settled in Brimstone, and the town's academic history culminated in the founding of the Brimstone Institute of Demonics, an academy dedicated to the study of demonic magicks and its various applications.

Over the years, however, Brimstone began to change, and not for the better.  The town is held in the iron grip of the Sulfur Blood crime family, and some twenty years ago, a mysterious attack upon the populace caused major changes.  Entire passages of history were erased, and the once-prestigious B.I.D. was forced to cease functioning as a private school and downsize in order to open its doors to public.

Why this is, however, nobody can truly say.

Historically, Glutton tribes lived either on the Hellish coastlines in thatch huts, or on the ocean itself in pontoon towns.  They mainly subsisted on a diet of fish, seaweed and wild grains, but were open to trying anything new.  Glutton communities were close-knit, and as a result, many future generations would find themselves comfortable opening up to strangers, granting them the image of a gentle and friendly people.  Their willingness to explore has lead them to develop many advancements in the field of gastronomy, and as a result, many historically famous Hellish chefs were Gluttons.

Armed with maces comprised of tough crystalized sugar, Gluttons boast a mastery over the element of water.  Additionally, they are capable of magically adjust the size of their own bodies; a kind of magic referred to as magnimorphisis

Fallen are the demons of Envy, and as a result are infamous for their piercing green eyes.  Their skin tones range from dark grey to pitch black, and they are noted as being one of the tallest races of demon alongside the Oni.  Upon their back they have grey wings with feathers composed of cartilage, and they have but one grey horn that sprouts from the forehead and loops around the entire head like a halo.  Interestingly, their natural body temperature is lower than that of other demons, and their bones are hollow in places, aiding flight and reducing their overall body weight.

A traditionally isolationist race, Fallen tribes were generally nomadic; never staying in one place and always following the migratory paths of their prey, be they eastern brimicervs or western buffalo.  Even within family units, individual Fallen would be highly suspicious of one another, constantly coveting that which their companions possess and jealously guarding that which they themselves own.  As a result of this antisocial behaviour, many Fallen are stereotyped as being creepy and standoffish, though as with most generalisations, such things aren't always true.  Indeed, while mistrust runs in a Fallens' blood, they are also famed throughout history as being unwaveringly loyal to those they are close to, and their natural adaptability makes them excellent allies both in ancient times and modern life.

Wielding bows of flexible volcanic glass, the Fallen are able to manipulate the wind, as well as the natural processes of their own body.  They can render themselves invisible, breathe underwater or see in the dark - among other things - thanks to their innate mastery over a process known as ambitioditanic modification.

Ever slow and ever steady are the Golems, patron demons of Sloth.  Though they tend to have terrible eyesight, they more than make up for their lack of perception with impressively thick skin; looking almost as though they're made from stone due to the brown pigmentation and occasional discoloured patches, ranging in appearance from granite to limestone.  They have short horns that match the colour of their skin, and in place of feet, Golems have cloven hooves.  

Golems historically settled in rocky regions such as mountains or canyons, rarely ever moving around or migrating from their home settlements where they raise cattle and practice masonry.  Uniquely amongst other demons, Golems were the first race of demon to have any kind of organised religion, namely the Sunmos Sects; an order of monks that strive to attain enlightenment through meditation and deep sleep.  Another unique quirk of the Golems is their effect on other demons.  While the natural pheromone' of all demons work only on humans, the natural chemicals in a Golem's sweat has a relaxant effect, which seems to tie into the race's easygoing nature as a whole.  Given their role as a demon of Sloth, it doesn't take much to put a Golem to sleep, and it takes a whole lot to wake one up.

Armed with shields of toughened granite, Golems are masters of the element of earth.  In addition, they are capable of reaching a certain state of mental attunement when they sleep, granting them the ability to manipulate physical objects with their minds.

Though records indicate that Imps originated from treetop villages in Hell's many forests and jungles, their innate adventurousness led them to spread all over Hell.  As Imp societies ran on a "if you can steal it, its yours" line of thinking, they quickly earned themselves a reputation for being little more than opportunistic thieves and petty vandals.  However, their nimble fingers and sharp eyesight also led to them becoming excellent craftsmen.  Many of the technological advancements made in Hell were actually derived from human inventions that had been stolen by Imps and subsequently reverse-engineered.

Though they once carried crossbows, it is said that as a reward for bestowing the knowledge of human firearms upon Hell, Imps were granted access to revolvers made of lead.  They can also control plants and communicate with animals, as well as transform into them in an act known as bestimorphisis.

As the demons of Hubris, Nymphs take pride in their appearance.  Boasting slender bodies, golden hair and flawless yellow skin, they would appear almost ethereal if not for the short horns sprouting from their foreheads.  With long pointed ears, they have an acute sense of hearing, but for some reason that they themselves do not yet know, Nymphs are incapable of digesting meat.  Additionally, their entire body acts as a conductor, and they are capable of generating electricity within their bodies.

Originating from the highlands of Hell's eastern continent, Nymphs prided themselves on being the original producers of luxury goods, from gold and precious stones to fur garments and finely-worked wood.  Though their high-and-mighty attitudes hampered business relationships with the other races, their natural talent for performance and music more or less made up for this.  Many Nymphs find themselves in the entertainment, fashion or cosmetic industries, though some are trying to break away from this norm in an effort to prove that their people are worth more than their looks.

Armed with spears of conductive gold, Nymphs are highly attuned with electricity.  In addition, they are able to create and control all manner of illusions.

Easily the largest race of demons, Oni are the orange-skinned patrons of Wrath.  A tall and muscular people, they tower a head above most other demons, their visages made all the more impressive by the rocky red horns jutting from their foreheads.  A unique trait possessed by the Oni is the unnatural sensitivity of these horns, owing to the tightly-packed nerve clusters within.  Supposedly having one's horn touched is an incredibly painful experience, however if grasped by someone whom the Oni is very close to, it's said that an altogether different sensation is felt.

Historically, Oni made their homes in the most inhospitable of climes, from the hottest volcanoes to the coldest glacial plains.  Forming clans comprised of multiple family groups, they would remain isolated from other settlements as they temper their minds and train their bodies, constantly honing themselves for the next fight.  To most, Oni are gruff, stubborn and quick to anger, and for the most part that's true.  But those that can get past their flinty exteriors find that they tend to make incredibly strong and unwaveringly stalwart allies.

Capable of swinging massive bronze axes, Oni can supplement their massive strength with magical flame.  In addition, they can manipulate and control the forces of kinetic and potential energy, further enhancing their physical capabilities.

The all-female demons of Lust, possessed of iridescent purple skin and enchanting beauty.  In addition to lengthy yellow horns, they have small batlike wings and long tails tipped with heart shaped spades, though they are incapable of flight.  Many make the mistake of viewing Succubi as little more than shapely sex fiends, when in fact they are deceptively cunning and remarkably charismatic.  They are also the most maternal of any demon, as when presented with a child, a Succubus will protect it like it's their own.

Succubi were usually quite interspersed throughout Hellish history, with only one major settlement ever being founded; Phrodival, a large town built around a lake in the centre of a meteoric impact crater.  Their shared history is a rather murky and secretive subject, though what is known is that many Phrodival Succbi consider themselves followers of a woman known as Lady Fesser, who was the revolutionary founder of the town and an innovator in practices both magical and psychological.  

Able to effortlessly wield leather whips, Succubi have a unique mastery over shadows.  They are also masters of psychomancy; the art of charms, suggestion and mind control.

It's difficult to ascertain the commonalities between Incubi, considering their rarity.  Like their Succubi counterparts, they are demons of Lust, but are male and have blue skin.  They posses the same horns, wings and tail, though the spade is inverted, appearing as a spike instead of a heart.  Their are some minor differences in their biology - sharper teeth, tougher fingernails - but the reason for this is currently unknown.

Incubi births are few and far between, often inciting confusion from the mothers who were most certainly expecting daughters.  Though demons of Lust themselves, they are noted as having much more tempered appetites once they reach sexual maturity, though are generally just as charming and charismatic as their purple-skinned sisters.  Like Succubi - and all other demons, besides - Incubi grow in stages.  However, right as they are about to turn twenty-one years of age and progress to the third and final stage of growth, they disappear.  Without a trace.  There are no recorded instances of full adult Incubi.

With one notable exception.
