Okay, I’m hyperfixating on Helluva Boss and Hazbin Hotel currently, so I’m going to try and summarise the universe and now it works for my own use.
But first: Power Scaling.
The Average Human>The Average Sinner>The Average Hellborn(Imps, like Blitzø.)>The Average Exterminator>Charlie>Overlords(Vox, Alastor, Carmella)>Sins>Adam, Eve and Lilith>Seraphims(Sera and Lucifer)>God.
Sinners are Mortals who were condemned to Hell, as opposed to Hellborn like Charlie, who was born in Hell and therefore pardoned by Lucifer from the Exterminations. It can be assumed that Heaven has a similar distinction.
The Overlords, as seen in Episode Three of Hazbin Hotel at the meeting place, appear to be the eldest or most powerful Sinners. We know they’re Sinners and not Hellborn, as Carmella and her children are targeted by the Exterminators.
The Sins, as we see in Helluva Boss, appear to be extremely powerful, and are likely Hellborn, as as far as we know all of them are alive and none of them are on the Overlord Council.
Okay, so Hell has Seven Rings, each for a different Deadly Sin, but the shows almost entirely take place on the outermost ring, Pride, as Sinners are confined there.
Now, in classical Religious Texts, Lucifer is the Demon that represents Pride, so it is unknown whether his title as ‘Ruler of Hell’ is true, or simply called that as he rules the Pride Ring where everyone lives. I assume he rules all of it but lives in the Pride Ring.
Speaking of the Sins, in Helluva Boss, we meet several of the other Sins. We meet Gluttony, or ‘Queen Bee’; Greed, or ‘Mammon’; and Lust, or ‘Asmodeus/Oz’. Also Belphegor is mentioned by Bee.
In Classical Texts, we know the sins are:
Envy, represented by ‘Leviathan’
Pride, represented by Lucifer
Greed, represented by Mammon
Wrath, represented by ‘Satannas’ or Satan
Lust, represented by Asmodeus
Sloth, represented by Belphegor
And Gluttony, represented by Behemoth. This implies that Queen Bee’s full name is Behemoth.
We have yet to meet Belphegor, Leviathan or Satan, though Belphegor has been mentioned.
We know the vague location of Lillith, Lucifer, Sera and Adam. But Eve is a mystery. I assume that either Eve is just a citizen of Heaven, as she didn’t want to join Adam in Exterminating, though Adam never mentions her. OR Eve was sent to Hell, which, as she is not on the Overlord Council - which, she would be, being that old - implies she was exterminated, likely by Adam himself.
Alastor is working for Lilith, as is already heavily theorised.
But why? Something happened seven years ago, in which both Alastor and Lilith disappeared.
Zestrial believed that Alastor had ‘fallen to Holy Arms’, which likely means that he believed he had been exterminated.
Lilith is apparently in Heaven, having made a deal with SOMEONE, that is being cashed in at the end of Season One.
Somehow Husk knows that someone owns Alastor’s soul.
Let’s say Alastor was almost killed by an Angel in an Extermination seven years ago. But how? He held his own against Adam for a while, he could definitely avoid being killed by the Average Angel. And the fact that Adam had never seen him before implies it wasn’t him who defeated Alastor. So we can rule that out.
Unless… Alastor’s always been power hungry. What if he took advantage of an Extermination to use the portals the Angels used to get to Hell to escape to Heaven. Perhaps Lilith made this same trip, and they were caught. But why would Lilith make that trip? According to what Charlie tells us at the beginning of Episode One, she enjoyed her time in Hell. For that, I have no answers for now. I’ll rewatch the show later. In my head, maybe Lilith was planning to get Charlie into Heaven?
But Alastor escaping to Heaven and being caught makes sense. Perhaps he was held prisoner? But why not kill him? Maybe someone already there, let’s say Lilith, saved his life in exchange for servitude, keeping him there for Seven Years until she saw that an Angel was killed in an Extermination, or saw that Charlie was starting the Hotel, and sent Alastor to protect her.
Only other question: who the fuck is Stolas? They say he’s a Prince, and his status is respected by most of The Pride Ring, but he’s clearly not related to Lucifer or Charlie. My guess is that he’s somehow descended from Eve, as he’s clearly Hellborn, or maybe his family are more Nobles than actual rulers, as we never see any politics going on with Stolas. Also, he’s referred to as Prince, so is his Dad alive still? If he’s dead, then how? Can souls die of anything other than being killed? Was he exterminated? If so, how? He’s Hellborn. Unless.. well, Stolas’ family has the Grimoire, which allows them to go to the human world. Maybe all of Stolas’ ancestors were killed there? Or just assassinated by other demons?
