Succubus

Succubi are numerous tanar'ri demons, many under the command of the Abyssal Lord Graz'zt, but in the whole, they are ruled by their Queen, Malcanthet. The female child of a succubus and a human is traditionally called an Alu-fiend and the male child a Cambion. However, the offspring of an alu-fiend or cambion's union with a human has no specific name but falls into the larger category of tiefling.
