Hazbin Hotel lore explained: Everything to know for season 2 that the show doesn’t tell you

I’ve never encountered a show structured like Hazbin Hotel before — possibly because there hasn’t been one. The closest parallel I can make is to the structure of J.R.R. Tolkien’s Lord of the Rings novels and The Silmarillion and other posthumous books: The comparatively small story of two hobbit journeys — the canon work published during Tolkien’s lifetime — is in some ways dwarfed by the millennia-long history documented in his unfinished background material. In the same way, there’s so much more background and setting lore to Hazbin Hoteland its sister show, Helluva Boss, than what’s appeared on screen.
