I opened the 1st gate of Hell, ruled over by Belial and the 9th gate of Hell, ruled over by Satan. I was wondering how can I close it if I ever want to
From my experience, the best thing to do is to simply ask. Call upon Satan and give him a sentimental sacrifice, like an old love letter, and that should do the trick quite frankly.
It could be more in depth than that, I’ve never opened gates before, but try this if it ever does come to a need.
