I’m wanting to try an experiment, and every single time then I look for spirits that are associated with feelings of dread or Terror, I keep finding silly Creepypasta links.
Thought I’d try and ask you guys. If I can’t come up with anything, I do have a plan B, but working with that many parasites at one time can be dangerous.
Phobos comes to mind. Greek personification of fear.
Parasites work well
To cause fear in people, I personally would dive into the Cthulhu mythos. Fear and madness, what better could you ask for?
Practically any entity that can access the astralscape and your mind.
The Lord of Destruction Chaugnar Faugn, or Lord Cthuga of the Vampyre Djinns
How did I completely forget about Big Daddy Cthulhu?
Dipping in to Lovecraftian mythos, there’s also Yig and Nyarlathotep that may be suitable.
