Demon Realm

North of the known demon realm.

Western part of the demon realm.

The **Dark World** (*Makai*, **魔界**) **Demon Realm**, **Demon World**, **Devil Domane**, **Devildom** or **Magical Realm**, is another dimension next to the human realm. It is the original birthplace of all demons and only a few humans have ever visited it. The realm is a dangerous place of curses and magic, with a corrupted high fantasy setting.

The Dark World is connected to the Human World with **Demon Gates** that appeared more numerous in recent times after the Peninsula Conflict, in which the human town Amidahara was strongly damaged.

However, demons have been entering the human world even before this. As far, older but inactive gates have been found all over Japan.

## Connection to Human Realm

The Dark World formed next to the Human World out of the Mother Sea, a structure that contains all Universes. Beings of the mother sea called "Aion" visited the dark world and effected bloodlines, creating primordial Vampires in the process. Those vampires and other demons in turn visited the human world, creating the mixed blood of human and demon, that is the foundation of Taimanin. While most humans stayed unaware of demon existence outside of legends, demons knew of their weaker neighbors.

The Dark World had been ruled at some point by ancient gods possibly creatures from the Otherworld, which had been later banished by the great ancestor of the witch Lilith and Ancient Dragons. However, those ancient deities are still feared and people like Oryou face discrimination, as her inhuman look, is seen as a curse of those born from those past rulers.

At some point in the ancient past, a deal between humans and demon was made, that prohibited intervention and disturbance of the other realm. Taimanin clans Individually would try to uphold those rules in the Human World, but some families were stranded in the Dark World and became the Ryomanin. In the most recent times the deal between demons and humans was broken by the humans, if it was a slow process or a key event is not clear. Technology and magic of both worlds had mixed. Now Taimanin tried to stop the encroaching corruption, with tech ever moving forward into the unknown.

Cooperation talks between demon nobles and earth governments held in secret mostly broke because of sabotage, leaving the realms in uncertainty. With the Peninsula Conflict between humans and use of a "nuke" (magical event) in Amidahara by the UFS (USA), everything further escalated. Only shortly after, around the human realm, specially Japan, new **Demon Gates** appeared. Cities with such a gate became criminal paradise of trade, but in turn also towns of the dark gate near gates became prosperous.

## Geography and Topography

Unlike the name would suggest, the Dark World isn't dark or biblically hell-like, but a place that like earth has terrestrial features and day and night cycles. The realm has different regions, with different climates, vast wastelands, fairy forests, stormy oceans, burning planes and even stranger places. The areas are still highly dangerous, as animalistic demons or tribes of demon bandits are roaming the plains. Some demons powerful enough to change the environments themselves.

Not knowing the local rules, will often end in being enslaved and captured, if not killed. Unlike the Human World the towns located in the Dark World, are either village sized or medieval kingdoms with little reach beyond their borders. Some cities specifically formed near Demon Gates like Gate City, and are centers for trade.

There seems to be at least one large landmass. The **western side**, from the bigger capitals, is known to be the Midwest of the demon realm. Only small countries with forests are located in this place, with multiple skirmishes taking place. The **southern side**, is mentioned of an area of barbarians. The **northern side**, contains 3 large regions of the Flame and Blood Lord, as well as the Phantom Lord in the north-east. The Blood Lord area is also mentioned to be on the coast, with one of Dark World Oceans, called the "Winter Sea".

### Effects and Biology

Any animal or human that stays too long in the realm can be corrupted by it. Which can either lead to a slow change of character or physical alteration, creating more demons. Depending on which region one remains in the Dark World, the changes can be stronger or result in different types of changes. (Burning planes create Inferno Demons, as an example). Beings that are already changed or inherited demon blood are less affected by this.

## Policy

There is currently no single ruling body of the Dark World.

However, a coalition of nine noble families seem to have the most influence over the Dark World, with Hell Knights protecting the system of rule. A feudal society where each race's king and his nobles hold territory. There are many lands in the demon world that are not under the control of powerful nobles. Independent tribes/clans and powers in those areas defend themselves, in a less centralized but still very capable way, against bandits or other factions.

Powerful demons are in a constant power struggle to take each other over or stay out of each other's way. There is a hard class system in place, separating something like a high nobility Vampire from a low class Dark Elf. However, the noble families also uphold a degree of law with the help of the Hell Knights which are allowed to take down entire tribes or nobles that go against the coalition

Most try to also follow the rule of non-interference with the human world but more demons visit the human realm. Demons also trade with the "Hell Cities," towns of the human realm that are connected with **Demon Gates**. Examples of such locations would be Yomihara and Amidahara.

Most demons view themselves as above humans but trying to directly take over the realm, would come with the risk of a two front war with competition. Also, the human world with his high amount of technology and access to Taimanin isn't easily taken over. Leaving their realm in a sort of balance, in which weaker demons are hunted down, while stronger demons rule and keep each other in check.

Some of the most prominent rulers of the dark world are:

### **Noble Lords**

* **Demon King/Lord**: Former and yet unnamed ruler, true master of the 9 Noble Demon Families. Currently, vacant position.
* **Chancellor**: Bismarck is the current defacto ruler of the 9 Noble Demon Families. Making him the currently highest authority, in the demon realm.
* **Corpse Lord**: Teutates (or Death Wraith King), King of the **Wraith**. Wraiths and Death Wraith, view vampires as their natural enemies.
* **Phantom Lord**: Kamadeva, Ereshkigal, Shiranui (or Kuroi Ryuuji). The King/Queen of the Incubus/Succubus either passive force or one aggressively aiming for more power.
* **Blood Lord**: Carla Cromwell, Carla's father, another King of the Vampires which is not part of the 9 nobles.
* **Wise Lord**: Marjaana, Wise Queen, a Brain Flayer Queen not a demon but respected for her power.
* **Night Lord**: Ceres, the Night queen, a rival of the Incubus/Succubus for their control over brothels. Lord of assassins.
* **Flame Lord**: Heliogabalus Gaap, an Inferno Demon, has been killed by Teutates and disowned, as he tried to become the demon king.

### **Regional Nobles**

These are not necessarily connected to the 9 Noble Demon Families and can be fully indepedant.

* Death Wraith King, King of Death Wraith, which is an enemy of the Corpse Lord.

* Ixchel Ludara, the queen of a small kingdom.
* Roselina, Dryad Queen. Friend of Merriam.

## Trivia

* Traveling at day, is rather risky and requires guards, but traveling around at night outside the cities will often result in death, given numerous beast demons.
* King and Queen, are purely merit positions and multiple demons can "claim" to be the King or Queen, by just owning a large area of land and multiple subjects of a species. As such, multiple Wraith, Vampire and Incubus Kings/Queens, existed at the same time and were in conflict.
* Both the Dark World and Human are connected to the Mother Sea.
* The Ryoumanin are the Dark World equivalent to Taimanin and try also to preserve the rules.
* Funny enough, both Human and Dark world, do not fight each other, simply because they are too busy with internal struggles and attacking the other realm directly would make them a target for anybody else.
* It is unknown how big the demon realm is, or even if the planet it is located on is "round".
* Many magical weapons, wander the demon realm, some have created destruction around it, including Feral and Rivalis.
