Ok so I was walking past a forest and some more like alot af faries started following us. Well not long after, my friend sees this figure crossing the road. Then she sees a figure in all black bell sleeves and lantern with a red and orange flame it followed us the whole way home and it's still around her she feels drained of energy and wants to sleep but I won't let her because I think it could be a grim. Please help.
have you tried a banishing spell? It may not be a grim but black annis which is distantly related to faeries in some beliefs, that's why I'm thinking that. try figuring out what it is first and do a banishing spell for it specifically. another option but more risky is trying to bind it from doing harm to your friend.I would try the banishing first though.
