I have heard of this being possible. I have searched all Iover Google and found articles revolving around this concept. I have contacted my most familiar demon sense, King Paimon about this. But I only get back that it is doable. Does anyone on here have any information on how to obtain one of these companions? I know they like red wine as an offering, and can be conjured if you know their name, however I can only seem to find the names of the most powerful demons. I know a demon who haunts a friends apartment but I cannot get there as it is across the States. My friend only got the first 2 letters of its name... does anyone know about this?
