Hello lovely. Late to the discussion but I think you’re covered. When it comes to religious background, I have a religious background (very strict Christian) so fear of demons is very real. Loki scared the hell (scuse the pun Loki, Hel being your daughter, couldn’t resist please don’t set my altar on fire 
) out of me for years, but being the trickster he is, he introduced me to the darkside (no I’m not going star wars, one puns enough ), through the twisty and windy road (feel there’s another pun in there, is Loki writing this 
)?
I don’t know if you’ve got the links but here’s the demon chat.

The Demonolatry Club (Please Read Content Warning) (Part 1)
If they’re already in another post, sorry, am catching up.
Here’s a book you may like (it’s Christian based), but backs up biblically which should help from a Muslim point of view too, that the dark deities are alienated by the church, not the bible or God. How long it’ll be available before it disappears I don’t know, but it may be of interest.
Knowledge will get rid of all fear, and let’s face it, as Loki’s girl (probably the deity with one of the worst reputations in history 
), if anyone was going to go up in flames, it’d be me, but I’m still here, so it can’t be all bad right? 
Now I’m going to read everyone’s posts, and realise what I’ve said has already been said lol
