I've never seen a goertia demon,to my knowledge,but if you had gone and actually read any of their summoning forms,you would know why i said what i did.
And I HAVE seen "demons",more than once .
Just because you can't see them,doesn't mean other people are as boring.
And I've used goertia demons in my rituals. I'm particularly fond of Lerajie ,and one of my cats was named for Astaroth ,but I've been versed in goertia demons for over 20 years .
I find it interesting too that you claim to have "used goertia demons in [your] rituals", and yet you seem to be blissfully unaware of the fact that it is GOETIA, not "goertia". Where did the "R" come from? Did a demon put it there, perhaps?
