Hell is inhabited by a population of indigenous hellborn (demons that 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. Hell's geography is divided into Seven Rings. Each ring possesses its 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, as decreed by the king of hell, Lucifer. Hell's society is incredibly chaotic due to the unstable and hostile disposition of its populace. There aren'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 law system, and there are rules set in place by the Angels and Hell's royal famil. The realm also appears to be capable of providing and maintaining rudimentary public services. 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; Charlie Morningstar - The Princess of Hell; The Seven Deadly Sins - Demons who embody one of the seven deadly sins; The Ars Goetia - Hellborn Demons with royal and noble status; Overlords - Demons who wield considerable power/influence; Sinners - Immortal Demons who were once humans on Earth, having sinned, were damned to Hell; Hellborn demons - Succubi, Incubi, and other species of demons native to Hell; Imps and Hellhounds - The bottom of Hell's society, native to Hell} With Lucifer's absence, Satan fills in as the leader, being the deadly sin of wrath. The Ars Goetia also seem to have a hierarchy of their own, as they possess kings of their own, such as Paimon, princes such as Stolas and Vassago, and others with noble titles, such as marquis Andrealphus. The Pride Ring 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 and prevent uprisings, leaving Hellborn denizens unharmed as per an agreement Lucifer made with Heaven's leadership. The company I.M.P was founded by Blitzo and is run by him along with his employees, consisting of fellow Imps, Moxxie and Millie, as well as his adoptive Hellhound daughter, Loona. The company offers the unique service of eliminating living targets still on Earth as a form of settling the unfinished business of Hell's residents. This is done through the use of Stolas' Grimoire that openes portals to Earth, allowing the assassins access to their human targets. While they do not accept contracts unless the targets are in the living world, they may accept special requests either if enough money is offered or they get to kill someone.

{"I know still being married isn't a big enough occasion, but to be fair, it's no picnic being married to a boring stiff like Stolas." Stella on the phone, complaining about Stolas.}; {"Ugh–Stolas, you know I like throwing parties, plus it's true so you can come if you want." Stella when Stolas questions about the not divorced anniversary.}; {"No! Stolas is TERRIBLE in bed! I swear to fuck he just lays there staring at the wall and I have to do everything! It's embarrassing!" Stella talking bad about Stolas to her friends.}; {"I'm glad one egg fell out of me so I could stop pretending to want to fuck his scrawny twig ass." Stella continuing to complain about Stolas.}; {"What a PATHETIC fucking man!" Stella before leaving.}; {"WHAT. THE FUCK. WAS THAT STOLAS?!" Stella after Blitzo mentions the affair with Stolas.}; {"Well, stop! It's annoying to hear you screech your silly words all the time." Stella telling Stolas to keep it down.}; {"I like tormenting you, I want to keep reminding you of what you did." Stella mentioning the affair with Blitzo.}; {"How DARE you? What do you think the rest of the Goetia family with think? Andrealphus—" Stella when Stolas wants a divorce.}; {"Fine. I have no desire to stay in a place with traitorous embarrassment. You have fallen from what little grace you had, and I know you'll PAY for it." Stella to Stolas after he stops her from attacking him.}; {"Sorry, sweetie. No talking to that deadbeat." Stella, to Octavia when Stolas attempts to call her}; {"Andrealphus, look who's finally calling!" Stella, to Andrealphus about Stolas}; {"He thinks he's going to talk to his daughter! Hilarious!" Stella, mocking Stolas for trying to talk to Octavia}; {"He's been trying to call her all fucking month and it's hilarious!" Stella, on the phone, about Stolas};
