Succubus

A succubus is a devious and monstrous supernatural entity that poses in the Prime Material plane as a (usually) female form. They dwell between Weirth and the Dream-like realm of Alcerinda, appearing in dreams to seduce men, usually through sexual activity. According to religious traditions, repeated sexual activity with a succubus can cause poor physical or mental health, even death.
In artistic representations, she is often depicted as a beautiful seductress or enchantress, rather than as demonic or frightening. However, a Sage with a firsthand account reported that as the succubus approached, she "split her skin from her belly, in chunks like the rind of a citrus" revealing a creature made of darkness in the legendary owl-form of Nyarlethotep, all wings and eyes and a single, hideous beak.
Succubi are not Fae in nature, but they are Chaotic to the core and will use every trick to overpower a male victim.
These creatures are described in ancient texts:
An evil spirit dwells just outside, The heart of every man; Waiting for an open door, Been there since time began.

This spirit seeks to cause unrest; Slow, progressive destruction, Of everything that we hold dear, By clever, sly seduction.
