Tried eating the Illuminati egregore.
Broke apart their stone Eye of Providence symbol and found a glowing red core inside. Ate it. This was yesterday.
Next day I was completely overcome with hopelessness and despair. Recognized this as being caused by something on the astral level since I've experienced faulty invocations like this before. I really didn't want to vomit up the core though since I felt a nice red power energy when I ate it and got interesting dreams the night after. Eventually though the suicidal thoughts got too intense so I reached into my belly and pulled the core out. Felt better immediately.

Didn't know what to do with it and it seemed to want to stay floating around me so I made an attempt at binding it to an old hard drive I had. Not sure if that'll result in anything interesting happening or not. Might try purifying it or something later. Still recovering from the effect this thing had.
