Looking for Ballad for Witches/Spells Theme

Hello, all!

I am looking for a ballad that goes with a witches/spells theme for my show choir this year. It doesn’t necessarily have to be a pop/theater/usual show choir-type song. I’d settle for something that sounds like you’re casting a spell, or something that sounds mysterious. I’d like it to be a serious song, not something corny-sounding.

Any ideas?
Thank you in advance!
