Alu-fiend

Alu-fiends were the product of successful procreation between a succubus and a male mortal (usually human). The male equivalent to an alu-fiend was generally called a cambion. Successive offspring from either (with mortals) were demonic tieflings.

Description
Females were, generally, attractive or beautiful, going to great lengths at times to conceal their needle-like teeth and diminutive wings. They often possessed a high degree of sexual proclivity. Males, however, were harder to distinguish, as its "cousin", the cambion (produced from a female mortal), possessed many of the same "abyssal" traits. This led to a diminishing use of the patrilineal- and matrilineal-influenced terms as a whole; rather, products of both partnerings were considered "half-fiend".

Notable Alu-Fiends

 * Aliisza
 * Anderia and Estellia, the alu-fiend allies of the nabassu Viscaris

Though apparently not the daughter of a succubus, Graz'zt's daughter Thraxxia appeared in the form of an alu-fiend.

Background
Alu-fiends, also referred to as alu-demons, first appeared in the Monster Manual II 1st edition. They were described in the Monstrous Compendium Outer Planes Appendix and the Monstrous Compendium Planescape Appendix. While their exact statistics varied slightly, the general concept as the offspring of a succubus and a mortal male remained true.

In the 3rd-edition Dungeons & Dragons, half-fiends are presented as a more general template, in lieu of specific entries for each instance. There was no specific publishing of an alu-fiend template by official sources. However, a half-succubus template was included in a Dragon magazine and in a web article written by Robert Wiese, on half-fiendish variety, that appears on the Wizards of the Coast website.
