Ok, >>888597 is kinda right. Kinda very wrong. Satan cannot be summoned "anywhere" there are safe places, due to naturally both occurring and manmade collections of objects affecting spacetime. Buildings can be secured, amulets can be worn etc. However, in white or black magic, the summoner or worker is told to seek the highest available background energy that they are allowed to work with. Good/Neutral/Bad so ley lines, land, big fucking rock formations, artifacts left over from the last five civs, etc. BUT… those are not available everywhere, so, Masons, Temples, Castles, Large buildings. Built to rules of the energy you are trying to work with. Malls are a temple to what? Airports are a temple to what? Banking and Financial offices are a temple to what?
So yeah, was likely purpose built for something nefarious. Heres hoping you are on holy ground anon!
