Devildom

== Overview ==
The Devildom is one of the three worlds of Obey Me! and Nightbringer, alongside the Human World and the Celestial Realm. As mentioned in Obey Me!'s Main Story, the Demon King — Lord Diavolo's father — lies willingly dormant at the very bottom. Due to this, Lord Diavolo acts as the realm's de facto ruler.
As stated in Lesson 11-4 (OM), the Devildom has eight different layers. It is a separate realm from the Underworld, though both are known to have multiple layers. The Devildom in many ways is the opposite to the Celestial Realm, such as the Devildom always being dark, whereas the Celestial Realm is always light.
According to the Cosmo&Devil headline for Diavolo's birthday nightmare, the Devildom's timezone is DST, presumably meaning "Devildom Standard Time."
While not Devildom residents, it is possible for lost souls of the departed to end up in the Devildom, as mentioned in the Devilgram Surprise Gift. It is the job of reapers to collect these souls.
== Eternal Night ==
The Devildom has no sun, and so there is no sunlight. The world exists in a constant state of darkness, as mentioned by Mammon in Lesson 12-14 Hard (OM). However, according to Diavolo in the chat Regular Check-in and Barbatos in the chat Pitch-Black, the Devildom has different degrees of darkness depending on the time.
Despite this lack of daylight, demons still adhere to a "day/night" schedule where they sleep and are expected to awaken in the "morning" as evidenced by the fact that the demon brothers often sit down together for breakfast and dinner, as well as go to sleep and attend school/work at specific times.
As told by Solomon in the Devilgram Solomon Takes the Train, there is a legend about why the Devildom is always dark, and why the sun stopped rising there. The legend says long ago, the sun used to shine equally on all three worlds. However, the Devildom and Celestial Realm went to war over an accusation that one side was giving the humans guidance. The war lasted hundreds of years, until both sides decided to settle things by dividing the sun and moon. When the sun illuminated the Human World in the day, angels would watch over it. When the moon illuminated the Human World at night, demons would watch over it. This is supposedly why the sun no longer rises in the Devildom.
== Inhabitants ==
Note: For a list of native Devildom animals, see the Devildom Flora and Fauna page.
=== Aqua Guardians ===
Aqua Guardians are monsters that supposedly bring the rain. At least some of them are known to eat Ecstasy Oranges.
=== Banshees ===
Banshees are spirits and harbingers of death that appears as a black mist, as seen in Lesson 16 (NB). When someone is nearing death, a banshee may appear to those close to the dying person and cry and scream. If a banshee's cry is heard, it is too late to change the future the banshee foretells.
To be able to hear a banshee's scream, you have to either be connected in some way to the person nearing death, or have heard a banshee's cry before. Only those who have heard a banshee before will be able to hear its cries in the latter situation.
=== Bogeymen ===
As seen in Lessons 57 and 58 (OM), a bogeyman is an evil spirit that has the ability to appear as whatever someone fears the most.
=== Deathjokuls ===
Deathjokul are "born from the depth of the snow" and were thought to only exist in legends, but can be found in the northernmost region of the Devildom, as seen in Lesson 46-6 (NB). These monsters are very large beings, and while they may not look dangerous, they are very ferocious and like to eat demons. They are capable of speech, though seem only to speak using simple sentences.
=== Dark Pixies ===
Dark pixies are described as "little imps that like to play pranks," especially on Christmas. In the Devilgram Christmas Prank Kings, they are said to be the sort of pranksters who thrive on being scolded. Dark pixies cannot fly or speak, but can understand spoken language.
=== Demons ===
See the Demons category page.
=== Fairies ===
Fairies are magical beings with wings that are known to live in areas populated by flowers, such as Aurora Hill. When they dance in a circle, they create fairy ring flowers, as seen in the event Happy Birthday! Dear Solomon '22. Simeon mentioned in Lesson 52-12 (OM) that fairies are fond of hawthorn berries. As implied by the Devilgram Our Own Little World, only some fairies are smaller-sized.
=== Ghosts ===
See the Ghosts page.
=== Kelpies ===
Kelpies are monsters presumably similar to the Kelpie of Irish and Scottish folklore. They are capable of speech, and should their warnings to trespassers not be heeded, they can attack using powerful magic, as seen in Lesson 46-A (NB). The Devildom has at least one kelpie sanctuary to help protect their small population.
=== Sorcerers ===
While most Humans reside in the Human World, some human sorcerers are known to reside in, or at least work in, in the Devildom as well. For example, as mentioned in the Devilgram Bubbly Blue Soda, Oh My!, a considerably powerful sorcerer owns a flower shop and runs a café.
=== Spirits ===
There are many kinds of spirits that live in the Devildom, as mentioned by Barbatos in the chat All Kinds of Spirits. He also explained in the chat The Origin of Spirits and a Timeless Relationship that "Spirits are born from things that have existed for a long time, which is why they primarily exist in nature."
==== Fire Spirits ====
Fire spirits were mentioned in the Pop Quiz The Cursed Seed and the Fertilizing Flame. During the yearly Hellfire Incineration Festival, fire spirits from all over the Devildom gather to create the festival's main feature, which is a large bonfire. Fire spirits are known to eat magic, which makes them stronger. Lucifer also mentioned that music is considered a valuable source of energy for fire spirits.
==== Wind Spirits ====
Wind spirits are capable of controlling wind, and they live in a valley together, as seen in the Devilgram Wind Spirits & Surprises. This valley can be difficult to reach, as the path is narrow in places, and there are often sudden, strong gusts of wind. These spirits are fond of sweet treats, and if asking the spirits for a favor, it is recommended to bring some as an offering.
=== Vampires ===
As mentioned in the Pop Quiz The Vampire Special, vampires have their own territory in the Devildom. Diavolo wishes to be on good terms with the vampires, as he did not believe the mutated strain of vampiritis or its outbreak in said Pop Quiz was a purposeful attack to expand their territory. 
Vampires can be identified by their iconic fangs and their extreme thirst for blood. They have a powerful sense of smell, which makes them sensitive to strong scents. Vampires themselves have a distinct scent that can rub off on non-vampires. They can't stand garlic, especially the odor of death-warmed-over garlic, which is also a known vampiritis cure.
=== Witches ===
While most Humans reside in the Human World, some human witches are known to reside in the Devildom as well. One such witch lives on top of a mountain protected by traps, as is mentioned in the Devilgram Special Demonus. According to the Devilgram To Dreamland, another witch lives in the western forest. She lost her voice a long time ago due to a spell misfiring. This witch makes "Sleeping Sweet" which is an aroma oil that can be used to cancel out the effects of the Sleepless March, a magical item that can keep demons awake for 500 years. Both Satan and Solomon are acquainted with her but Solomon doesn't get along with her.
An ancient witch with reputation for being slightly eccentric lives in a house somewhere in the Devildom, as mentioned in the Devilgram Mini Mammon. Lucifer and Diavolo once ordered a special Demonus from her, but she put a shrinking curse on one of the bottles. According to Mammon, she pulls stunts like that "all the flippin' time."
=== Yetis ===
Yetis are large, burly creatures with their own language and are also capable of using magic, as seen in the Pop Quiz Conjuring of a White Christmas!. They are known to live on the Mountain of Boundless Permafrost, and set traps there to protect their territory.
=== Yokai ===
See the Yokai page.
== Known Locations ==
: See the Devildom Known Locations page.
== History ==
In Lesson 30-1 (OM), it was explained by Satan that the Devildom came into existence alongside the Celestial Realm, and exists in tandem with it. Shortly after its creation, a primeval forest covered the entirety of the Devildom.
In Lesson 3-4 (NB), Satan mentioned reading a book about the Demon Lord's Castle that said when the Devildom was still young, there were many stars raining out of the sky. There was also a giant pit known as "the Starfall," which was eventually used as part of the gardens of the Demon Lord's Castle.
Barbatos stated in the Devilgram Even Now, As Before that an older map of the Devildom from before he met Diavolo would look very similar - and have slightly different, but similar borders - to the current Devildom.
It is stated in Season 3 that the Devildom once went to war with the Celestial Realm. It is unclear what the outcome of this war was, but this war ended long before the Great Celestial War.
== Government and Law ==
=== Rulers ===
The Devildom is currently ruled by Lord Diavolo, but was previously ruled by his father, the Demon King. There have been at least eleven Demon Kings in the history the Devildom - as alluded to in the date Lucifer Love - though there likely have been far more.
Diavolo stated in Lesson 7-10 (OM) that he had not seen his father in several hundred years, due to him "slumbering at the bottom of the Devildom." It is known that the Demon King was not yet sleeping when the brothers originally fell, as Satan told MC in Lesson 9 (OM) that the Demon King was the one who assigned their titles from "oldest" to "youngest" of the brothers determined by their power.
As shown in Lessons 51 and 52 (NB), not all demons in the Devildom support the ruling family. Meowcao is known to be the home of many demons who oppose both the Demon King and Diavolo, including those who are upset that now angels and humans are being allowed to stay in the Devildom.
In Lesson 7-10 (OM), the previous Demon King who ruled prior to Diavolo's father was mentioned. His crown is either physically present or represented in a portrait of the Demon King housed in the Demon Lord's Castle.
As mentioned in the Fab Snap Satan's Curse, the Demon King Gardonus was a Devildom ruler from the Eighth Dynasty. This was an important period in Devildom history because Gardonus established a set of policies known as the "Wings of Darmius." These policies put political pressure on the Celestial Realm and caused the balance between the two realms to shift in the Devildom's favor.
=== House of Lords ===
: See the House of Lords page.
=== Law ===
The Devildom has a police force, as seen in the Devilgram Let Me Sleep!.
As explained in Lesson 38 (NB), if an individual commits a crime and is thought to pose a threat to all three worlds, the Celestial Realm, the Devildom, and the Human World have an agreement that such a person may be sealed inside Cocytus, the ninth circle of the Underworld. This imprisonment requires the consent of at least two representatives from each of the three worlds.
== Culture ==
=== Language ===
In Lesson 47-9 (OM), Belphegor mentions "Devildom script", meaning the Devildom likely has their own language.
=== Holidays, Events, and Festivals ===
: See the Devildom Dates and Holidays page.
=== Entertainment ===
: See the Devildom Entertainment page.
=== Food and Drink ===
: See the Devildom Food and Drink page.
=== Sports ===
==== Demon's Cross-Country Race ====
During one of these cross-country races, available paths covered the maze in the Jet-Black Forest and the ice floes of the Frozen Wasteland Mountain, as mentioned in the Pop Quiz Dust Storm Panic.
==== Devil Basketball ====
This sport is similar to basketball in the Human World, and was said to be a good sport for beginners in the Pop Quiz Love and Sports: The RAD Tournament. It was also mentioned that the rules allow a maximum of three spells in one game.
==== Devil Water Polo ====
This sport is similar to water polo in the Human World, and was said to be a good sport for beginners in the Pop Quiz Love and Sports: The RAD Tournament.
==== Fangol ====
According to Issue 3 of the RAD Newspaper, this sport is similar to American football, which means it is presumably a full-contact team sport. Beelzebub is part of RAD's Fangol team.
There is also a Fangol Ultra Bowl where professional teams such as the "Steel Falcons" and "Destroyer Sharks" compete for the championship. According to Mephistopheles in the Pop Quiz The Fangol Ultra Bowl, the Steel Falcons prefer to win through brute force, while the Destroyer Sharks take a more calculated approach.
==== Shadow Race ====
Shadow races are the Devildom's variation of horse races. Mammon regularly makes bets on the horses. In the chat Picking Favorites, Mammon placed a bet on "Darkness Falcon" and Leviathan placed a bet on "Golden Sucre" who is also considered "the daughter of Sucre Frenzy." The species of these horses are unknown, but in the chat An Amazing Perk, Mammon mentioned that abyssbred horses are bred to run in the dark, so it is possible that Shadow Races can take place at night with this species of horse.
=== Misc. Culture ===
According to the chat Damage Control, tipping does not seem to be an expected behavior in the Devildom. Beelzebub apparently never tips, and while certain demons, such as Lucifer, may tip the manager to compensate a restaurant for unpleasant customer, others may consider this as unusual behavior.
In the chat Despair, Asmodeus mentioned that it's considered good luck in the Devildom when a mirror is broken.
Lucifer explained in Lesson 35-10 (NB) that steam locomotives were once viewed negatively in the Devildom, because they were seen as "transportation for demons who lacked the ability to fly." However, now that more convenient travel methods exist and are more commonplace, a trend developed of demons taking trips via train for fun. This is especially true for noble demons, who according to Diavolo often use luxury trains to go on holidays.
Mephistopheles corroborated Lucifer in Lesson 36-3 (NB), and stated that trains were once considered "transportation meant for demon commoners."
== Technology ==
=== Internet ===
Demons have access to the Internet via computers or their D.D.D.s. According to the chat The Truth Behind the Jackpot, websites in the Devildom seem to start with "httpdevil." As seen in the chat Phantom Lyric 1, the subdomain of some websites is "vvv."
As mentioned in a few chats, for example The Things Humans Come Up With, demons also have access to Human World websites.
According to the chat Lifestyle Improvement, data is measured in "hell megabtyes."
In the chat Beware of Sales, some service providers and Internet plans of the Devildom are mentioned.
* Dead Devil Lite - service provider
* 666 Demon Mobile - service provider
* Hell's Faster Plan - internet plan
* Special RAD Student Plan - internet plan
=== Misc. Technology ===
According to Satan, in the chat The Allure of Paper, books of magic don't have e-book formats, and many technical books are only released in physical form. In Lesson 6-4 (OM), it was mentioned that Nightmare is a trial version of a Grimoire, and that the app is run by the Royal Library of the Devildom. This could imply that app developers are testing the possibility of making magical books available as e-books.
Hardware in the Devildom was originally modeled off of Human World technology, but Devildom software evolved in it's own unique way, as explain in Lesson 42-1 (NB). Software in the Devildom is a combination of electricity and magic. Leviathan explained in Lesson 42-4 (NB) that creating a D.D.D. app involved weaving magic into the program itself, which requires a certain amount of knowledge and technical skill.
In the Devilgram A Slice of Paradise, it was implied that the Devildom (and the Celestial Realm) does not have metered parking lots. When Luke, Satan, and MC were making a model garden, MC had the option to suggest adding a metered parking lot. If they did, Luke said that he has never heard of them, and Satan explained that they're "a place in the human world where you park your car."
Despite possibly not having parking meters, the Devildom does have cars. Mammon owns a Demonio 666 Lexura, and it was stated in the chat Let's Go for a Drive! 1 that he sometimes takes it out for drives. As mentioned in Issue 3 of the RAD Newspaper, there are also other forms of transportation, and the phone call Lost Child (Belphegor) specifically mentioned public busses. Steam locomotives were also mentioned in Lesson 35-10 (NB).
In the Devilgram What Luke Really Wants, Mammon explained that crane games were invented in the Human World, although the Devildom can receive shipments of them.
== Currency ==
=== Grimm ===
The currency used in the Devildom is called Grimm. Grimm exists in the form of gold coins with a skull relief or brown banknotes (as seen on the card Chibi Mammon II (Gluttony)). The player also uses this currency for various in-game expenses such as upgrading cards or unlocking spaces in Devil's Tree. Players can obtain Grimm by clearing battle stages or sending characters to work at :D JOBS. Tasks and Pop Quiz events also often include Grimm as rewards.
=== Devil Points ===
Devil Points are the digital currency of the Devildom. Although Lucifer can be seen holding a physical version in the card Greed and Pride. The player uses this currency to buy items or perform summons in Nightmare. Pop Quiz events also often include Devil Points as rewards.
== Geography ==
=== Climate ===
==== Seasons ====
In the text Summer's a Comin' from Asmodeus, it's alluded that there are four seasons in the Devildom despite the lack of a true day/night cycle. From this text, it can be assumed that the seasons function the same or at least similar to the four Human World seasons. Limited Items also suggest that the Devildom has four seasons. Items like the Three-Worlds Dango, Floaticorn, Cozy Fall Set, and Warm Scarf were each items designated for Spring, Summer, Fall, and Winter respectively.
==== Weather ====
It is known to snow at times in various parts of the Devildom, including where the House of Lamentation is, as seen in the Devilgram Snowy Bliss. There was also a blizzard at RAD in the Devilgram What Goes Around Comes Around. Some areas of the Devildom are presumably cold enough to be snow-covered either often or even permanently, as the northernmost areas of the Devildom seem to be in Lesson 46-6 (NB).
As seen in the Pop Quiz Cold Snap, the Devildom has a legendary and magical cold snap that is very rare, and has little documentation on the subject. In past occurrences that were recorded, this cold front was powerful enough to have frozen "all demons in its wake." However, this freezing effect was not permanent, and the demons thawed once the front had passed. The cold snap takes longer to affect humans than it does demons or angels. According to a website found by Leviathan, "the best way to counter the cold snap is to get fired up."
Other places in the Devildom use magic snow that isn't cold to create snowy landscapes and allow for events like snowboard competitions, like in the Devilgram A Perfect Winter Romance. Presumably magic is also used when it is made to snow to cool down Dogma Street, as mentioned in the chat Cooldown Period.
It also rains in the Devildom, as seen in the Devilgram Shelter From the Rain. The chat Plant Dad Troubles also implied that rain is a regular occurrence. As such, Barbatos does not use a sprinkler system to water the plants at the Demon Lord's Castle. According to the Devilgram Cooking on a Rainy Day, sometimes the rain can appear black depending on the weather conditions. However, in the chat Suspicious Weather, there was mention of acidic rain, which Lucifer warned that humans should avoid.
When light is refracted to form a rainbow in the Devildom, the resulting color spectrum is different than the rainbows in the Human World. In the Devilgram The Chaotic Overtime!, the rainbow that appeared from a water hose was made of colors that MC described as "sinister-looking." It is unknown whether these rainbows form in the sky from natural rain or not.
==== Natural Phenomena ====
During certain months of the year in the late winter/early spring season, a natural phenomena known as "Devil Dusters" commonly form. As seen in the Pop Quiz Dust Storm Panic, these Devil Dusters are gigantic sandstorms that in addition to being naturally occurring, can also be created by Giant Dust Devil Birds.
As mentioned in the chat Hellmouth 2, a hellmouth is a Devildom phenomenon described as a "horrible chasm." Presumably, this means that a hellmouth is similar to a sinkhole. RAD is known to hold emergency drills so that students are prepared for such an event.
Belphegor explained in the Devilgram Our Summer Festival that "Orbs of Telescopic Fire" are a natural phenomena that sometimes occur around summertime in the Devildom. These orbs look kind of like floating soap bubbles, and can show a person images of events happening elsewhere. They are considered a fairly common Devildom phenomena. The orbs can be held, but will burst if not handled carefully.
Similar to in the Human World, the Devildom sometimes has aurora displays, as mentioned in the Devilgram Everlasting Snowflakes. In the Devildom, however, these auroras are created by ripples of magic, which is why their colors are never consistent.
=== Geology ===
This section contains records of The Devildom's unique rocks, minerals, sands, and soils, both magical and non-magical.
=== Flora and Fauna ===
: See the Devildom Flora and Fauna page.
=== Agriculture and Aquaculture ===
Farming is an important source of food in the Devildom. The Frost Flower Festival is thrown every 300 years to appease the White wolf of frost flowers, in the hopes that it will grant the Devildom good weather and a bountiful harvest. In the Pop Quiz Absolute Zero, the snow caused by the white wolf threatened to destroy all the crops in the Devildom, which would have led to widespread starvation. 
As mentioned in the Pop Quiz The Devildom Cooking Royale!, crops in the Devildom have a mind of their own. One year, crops all over the Devildom weren't producing as much due to the crops themselves going on strike. Some Devildom produce even came alive and ran away because they were dissatisfied with the popularity of Human World food. In the chat After a Difficult Conversation, Solomon theorized that the crops intentionally stunted their own growth, but were able to spring back once they were satisfied with the Devildom Cooking Royale or Devildom Food Festival.
Depravity fruit is cultivated in the Devildom solely to produce Demonus. In the Pop Quiz The Great Demonus Awards!, Mephistopheles explained that nobles, including his family, have invested in Devildom wineries. To celebrate a particularly abundant harvest of depravity fruit, the nobles once organized a Demonus making contest.
Just like in the Human World, edible plants and fungi can be foraged in the Devildom. In the Devilgram Simeon's Special Soup, Simeon said that the woods are home to many species you can't buy in stores. Also in this Devilgram, he and MC found an abundance of edible fruit trees in the woods. However, foraging in the Devildom can be dangerous. Some Devildom plants cause unwanted magical effects or are dangerous to harvest, such as funny fungi and ultimate pumpkins.
Edible clams can be dug from Diavolo's private beach similarly to how they are harvested in the Human World. In the Pop Quiz Pearls and the Beach, Satan stated that clams are dug year-round in the Devildom, as opposed to seasonally. 
In the Devilgram Pandas Mean Profit!, Mammon said that they don't have bamboo at all in the Devildom.
== Celestial Bodies ==
=== Moon ===
The moon in the Devildom is much larger than the Human World's moon. At times the moon gains a reddish appearance for a short period, known as a "bloody moon." According to Satan in Lesson 31-2 (OM), demons have worshipped this moon since ancient times. There is no way to predict a bloody moon until shortly before it happens. On the night of a bloody moon, a bloody moon competition is held at RAD.
As seen in the Pop Quiz Happy ☆ Holidays!, a book called "Secrets of the Devildom's Moon" details times when the Devildom moon's orbit varied, and the effects caused by this.
According to Barbatos in the same Pop Quiz, some believe that certain lunar phases of the Devildom's moon can cause erratic behavior in people, similar to beliefs in the Human World.
=== Stars ===
The Devildom sky contains many stars and constellations. In the Star-Crossed Lovers Devilgram, an autumn sky constellation is mentioned — the Pool of the Abyss — along with the myth associated with it. One star represents a beast, and another the maiden that was carried off by it. The nebula below the two stars symbolizes the pool created by her tears as she yearned to see her beloved.
Other known Devildom constellations include the Black Lizard, and the Serpent's Scales (also known as the Snake's Scales), which represent "favoritism" and "attachment" according to Belphegor in the Devilgram Secret Password for Two.
In the Devilgram Secret Dream Study Sesh, Belphegor mentions that the constellation "Fountain of the Abyss" can only be seen in the fall.
After the Great Celestial War when the seven brothers fell into the Devildom, two small stars appeared next to each other in the Devildom's sky. Belphegor told MC in Lesson 30-9 (OM) that these twin stars are his and Beelzebub's. He also mentioned in Lesson 39-20 (OM) that the rest of the brothers have their own stars, too.
There is a part of the Devildom sky that can only be seen from limited locations that looks like a group of stars are all clustered together, as if "someone tore a hole in the night sky and let the stars pour out." According to Solomon in the Devilgram Solomon Takes the Train, rumors say that the starry sky of the Human World comes through that tear in the sky.
=== Phantom Galaxy ===
There is an entire galaxy known as the Phantom Galaxy that is only visible at certain times in the Devildom sky. As Belphegor explained in the Birthday Pop Quiz Happy Birthday! Dear Beel and Belphie '23, the galaxy's visibility is unpredictable, in that it can appear multiple times in one year, or sometimes won't appear for centuries. No one can predict when it will appear until days before it shows up in the sky. It is also only ever visible for 24 hours at a time. This galaxy is called the "Phantom Galaxy" because it's impossible to record video or take pictures of it, and can only be seen by the naked eye.
== Leaving the Devildom ==
There are several ways to leave the Devildom, as explained in Lesson 11-4 (OM). One way is making use of one of several "external magic seals" that work as passages between worlds. All demons - aside from Diavolo, Barbatos, and Lucifer - must receive "permission in advance" before they can use the seals. This is due to the previous misuse of their free availability. It is strongly implied that Mammon was the perpetrator.
Another method, considered the "classic route," involves an individual walking through all eight layers of the Devildom on foot. However, it is considered "too long" and, as Lucifer mentioned, would destroy MC's psyche.
Witches or sorcerers can also summon individuals out of the Devildom, though there are alluded consequences to this method.
