This demon may take upon it two forms, the male form being the incubus and the female form the succubus. The succubus assumes the form of highly attractive women that yield to males in their dreams and receive their semen; by cunning skill, the demons preserve its potency, and afterwards they become incubi and pour it out into female repositories. Succubi draw energy from men to sustain themselves, often until the victim becomes exhausted or die.

A succubus massage parlor was installed at the Enchanters' Retreat, sometime before or during the Great Monster Uprising.

Succubi are members of the Supernatural and Fantastic Wayfarers Association.
