Hell

Hell is the primary setting of both Hazbin Hotel and Helluva Boss. It is where both bad souls, sinner and hellborn demons reside.

Description
Hell is the supernatural realm of demons. It is inhabited by a population of indigenous hellborn: entities which were born in Hell, and sinners: Humans who have died and have had their souls sent to Hell.

The atmosphere is presented as perpetually choleric, disorderly, and noxious, though capable of supporting carbon-based lifeforms. Hell's geography is divided into Seven Rings, as first revealed by the lyrics in "You Will Be Ok". Each ring possesses its own unique atmosphere, such as the Pride Ring possessing a permanently red sky, and the Lust Ring which has a blue sky.

Hellborn demons have the ability to traverse across any of the rings, made easily accessible via an extensive elevator network, whereas sinner demons are confined to the top-most ring, the Pride Ring, by methods and reasons unknown.

Hell's society is incredibly chaotic due to the unstable and hostile disposition of its populace. There isn't many rules in the world as it's kind of like a free-for-all and in constant anarchy, but despite this the inhabitants of Hell have their own law system, and there are rules set in place by the Angels and Hell's royal family. The realm also appears to be capable of providing and maintaining rudimentary public services, evidenced by the appearance of firefighters in the episode "Murder Family" of Helluva Boss.

Within Hell's civilization, there exists a crude form of hierarchy defined by power, with all of Hell being ruled by a king: the fallen angel Lucifer Morningstar, whose daughter and heir apparent is Princess Charlie.

The levels of this hierarchy are broken up from top-to-bottom as follows:
 * Lucifer Morningstar - The King of Hell
 * Lilith - The Queen of Hell
 * Charlie Morningstar - The Princess of Hell
 * The Seven Deadly Sins
 * The Ars Goetia - Prince Stolas and other demons with royal status
 * Overlords - Demons who wield considerable power/influence in the Pride Ring
 * Sinners - The damned souls of deceased humans
 * Hellborn demons - Succubi, Incubi, and other species of hellborn demons
 * Imps and Hellhounds - The bottom of Hell's society

Hell apparently suffers from mass-overpopulation which Exorcists from Heaven attempt to solve through the exterminations, which is a mass genocide of its inhabitants. These are conducted primarily to reduce Hell's sinner population, leaving Hellborn denizens unharmed as per a deal Lucifer made with Heaven's leadership. Charlie aims to stop this by giving sinners a chance to rehabilitate and redeem themselves by checking into her hotel and later ascending to Heaven.

History
Many years ago, Hell was accidentally created after Lucifer gave humanity free will by offering Eve the Fruit of Knowledge. After Lucifer and Lilith were cast into the dark pit, Lucifer ruled over Hell albeit not directly, but Lilith thrived in Hell, using her voice and her songs to empower all of demonkind and allowing Hell to grow stronger every day until an Extermination was put in place to prevent Hell from rising against Heaven.

Trivia

 * Vivziepop's original depiction of Hell as a location was first featured in her popular web-comic, ZooPhobia; it was one that the characters of Hazbin Hotel were originally due to fit in with, and that featured in her third year short-film, Son of 666.
 * Vivziepop confirmed that her Hellaverse and Zoophobia do not share the same universe or version of Hell, stating that their separate Hell-theologies are not compatible.
 * In fact, according to Vivziepop, the Hell of ZooPhobia focuses much more on mythological figures inspired by various world religions such as the Deities. Rather than the Hellaverse which is more of a personal representation of Hell by Vivziepop herself.
 * The Hell setting of both Hazbin Hotel and Helluva Boss draws its inspiration from a variety of sources. Vivziepop stated that she didn’t want the show to be limited to the perspective of one specific text or religion, instead wanting it to be much broader in concept. However, within that idea, Vivziepop did incorporate many characters and details from popular demonology texts, such as and .
 * Vivziepop does think that Hell has its own demonic languages, but also that the language-logic of the world was such that it "went without saying" and that English was only spoken as default as a kind of stand-in for the language of the show.
 * Hell runs just like a "big sleezy city", and everything in Hell is off-brand and terrible quality, including the movies. Vivziepop thinks there would be a lot of public domain cartoons on TV.
 * Hell is a very violent place where fights and aggression are common, but the only way a resident can be truly killed (i.e. their existence is permanently erased), or have serious bodily harm inflicted, is with Angelic weaponry. There is a black market for the Angel-adorned weapons, which are brought to Hell by the Exorcists during their yearly exterminations, and are then are collected by the residents of Hell.
 * Vivziepop played with the idea that, when a sinner is killed, their "dark energy" seeps into the ground to become part of the living fabric of Hell, hence why some objects and buildings appear to be 'alive'. She discussed a part of Hell that she planned to explore (if she was given the scope to do so) called Wonderland, where a great deal of this energy had collected and so is full of the most horrifying and dangerous monsters.
 * Hell has its own varied geography and climate, including jungles and forests, and its own native creatures. Everything in Hell is dangerous, inhospitable, and terrifying.
 * There are many cities in Hell beyond Pentagram, however Vivziepop stated that most of Hazbin Hotel will take place within the main city.
 * The main setting for Helluva Boss, and the location of the company's offices, is another city within the Pride Ring called Imp City, where many imp demons reside. It resembles a business district.
 * There is an area of Hell called the Cannibal Town, where many of Hell's cannibal population reside. It resembles a classic Americana town that is stuck in the 1910s, drawing inspiration from . This location can be seen in Alastor's comic, as he briefly passes through the area.
 * Although Vivziepop was still working out the details, and thought that much of it would function on "cartoon logic", she thought it made sense for sinners to arrived in a location in Hell that's relevant to their geographical location on earth. She joked that there is a nice town for the Canadians in Hell called "Heck".
 * The seas of Hell are a dark-gray/blackish color.
 * There is seemingly oxygen in Hell as evidenced by Moxxie's statement in the episode "C.H.E.R.U.B.", where he exclaims he was "losing oxygen" after being buried under debris.
 * In the "ADDICT" music video, it is shown that it can rain in Hell.
 * Allergies do exist in Hell and are part of the numerous inconveniences that occur at regular intervals. According to Vivziepop, life in hell consists of periods of stability, followed by periods of unpleasantness, which everyone is forced to deal with together.
 * Vivziepop joked that the only song available to sing in Hell's Karaoke bars is 'Mambo No. 5', and that she thinks it would be funny to license that song or similar.
 * Demons do celebrate holidays in Hell.
 * Instead of celebrating Christmas and expecting Santa Claus, demons eagerly wait for Krampus to visit their homes.
 * Hell doesn't directly share or use technology from Earth, but parallels it with devices of indigenous origin which are introduced alongside modern Sinners upon arrival in Hell. For instance, cellphones in Hell are called 'Hellphones' and they play anguished screams in place of conventional phone sounds. However, other technologies presented in both series are decades in advance of technology found on Earth. These include autonomous, sentient machines, cybernetic limbs, and even energy weapons.
 * According to Viviziepop, Hell years work differently from Earth years.
 * In the Hazbin Hotel pilot, Hell follows Earth's Gregorian Calendar, having 365 days in a year, however it is currently unknown if this is still canon.
 * As shown in Blitzo's calendar seen in "Seeing Stars", it is revealed that Hell has seven day weeks, which include a Sunday, and as seen in the contents of Stolas' phone in "Western Energy", a Monday.
 * As shown in the contents of Stolas' phone in "Western Energy", it is revealed that Hell segregates their mornings and nights as "AM" and "PM".
 * In "Unhappy Campers", after Moxxie and Millie stay on Earth for almost a week, five days, it is revealed that it has also been about a week in Hell as Blitzo yells at Moxxie "It's been like a fucking week", which may imply that Hell and Earth have the same or very similar flow of time as each other.
 * Contrary to the typical Hell presented in other media, Hell in Hazbin Hotel is a highly elaborate realm that punishes its populace without direct and unending torture as per its religious depictions. Punishment in the Hell of Hazbin Hotel seemingly derives from its continuous state of chaos and violence, with demons and sinners expected to consistently suffer from incidents involving such which they will experience for eternity.
 * While it is not a mirror image to Heaven, Hell does have a handful of similarities that parallel that of Heaven's. Noteworthy parallels include:
 * I.M.P being an organization that offers the opposing service of C.H.E.R.U.B.
 * Despite the purpose both services have, one difference is that C.H.E.R.U.B is of a bureaucratic nature (and possibly instituted), while I.M.P. is a freelance organization.
 * Species such as imps having their own part of Hell to live in, such as Imp City, a parallel to Heaven's Cherub Towne.
 * Demons operate by a hierarchy, parallel to Heaven having its own hierarchy.
 * Blitzo hints at the Hell-equivalent phenomenon of an earthquake in the episode "C.H.E.R.U.B", a hellshake or a hellquake. Although, it is unknown if this is an actual event or not. And if so, it is also unknown if this phenomenon only happens in selected areas in any of the Rings, since, according to Moxxie, such a thing does not happen or seem to exist.
 * The rarity of hellshakes might also be a subtle nod to, wherein Virgil explains that the ruins and crevices encountered in the 2nd and 7th Circles were all caused by the same tremor that occurred during the.
 * In "Truth Seekers", Blitzo mentions he dropped out of college, implying that there is a school system.
 * There are also pictures of Charlie and Seviathan at a prom framed at the Hazbin Hotel, which is specifically an event held at high schools.
