Ritual to Belial was successful before meeting him there was an old looking door after opening it i saw a red head with blue eyes. Was that the door to his realm?
Could be, I’ve never seen him with blue eyes but that means nothing, demons change their styling even more than teenagers.
I asked if it was him and i got a nod of the head. Ive read that you need to use divine power or names so he doesnt lie to the magician. And some kind of triangle but i dont think thats accurate with how you descirbed him.
Triangles are an almost universal theme in magick, they often appear as a gateway or portal.
his red hand reached out to shake mine as the pact was sealed
