Hell doesn't just mean the Abrahamic Hell, because Hell is a term used in other traditions too. Hell is another word for the infernal. Some just call it the underworld though.
"Hell... I don't know about it's location, but I do know that it's not just fire or a frozen lake or shit like that. It's various and has many ecological zones. I've been to forests, arctic zones, and probably more (I don't remember all of my projections). This is where a lot of Demons reside, and no I won't tell you who lives where because I know some Demons like their locations to be not well too known. It's not a totally horrible place to live, at least from my experience." ~Cruggles
