A demon from European folklore during the medieval ages, which takes the form of an attractive female to seduce men. Its male counterpart is the Incubus. They draw energy from men to sustain themselves, often until the point of exhaustion or death of the victim. Lilith and her daughters, the Lilim, are considered succubi.
"A type of demon that appears in dreams. It appears at the bedsides of men and sucks their life energy. A succubus takes the form of a woman, while an incubus takes the form of a man. When a succubus appears before a man, she renders herself into the image of the man's ideal woman. The succubus uses the life energy of her victims to spawn other demons and evil spirits. The reason that these demons use dreams is that they are not strong enough to physically attack their prey, but instead excel in attacking their minds. They are weak to anything holy, and placing a crucifix on one's pillow is said to ensure that they stay away."
