Alu-Fiend

The apple doesn't fall far from the succubus family tree.

The Alu-Fiend is a fiendish race introduced as part of the Planescape setting in Advanced Dungeons & Dragons. Specifically, they are the half-fiend daughters of Succubi - yeah, if you stop and think about it, that does make absolutely no sense - which makes them the female counterpart to the cambion race and a likely direct progenitor for a tiefling.

In practice, the alu-fiend is basically a wimpier version of its succubus progenitor, with similar spell-like abilities to charm people, read thoughts and teleport away from danger. They are characterised by hating themselves extensively, due to feeling like they have no place amongst either humanoids or fiends. Weirdly, though they aren't all evil, they are actually more evil than their cambion cousins; cambions can potentially be Chaotic Good, but alu-fiends can only be Chaotic Neutral or True Neutral in place of their traditional Chaotic Evil alignment.

Alu-fiends, also referred to as alu-demons, first appeared in the Monster Manual II. They were described in the Monstrous Compendium Outer Planes Appendix and the Planescape Monstrous Compendium Appendix. Because they really didn't have a niche for themselves beyond "watered down succubus", they vanished with the creation of the Half-Fiend template in 3rd edition.

The closest thing to a nod to their existence was the creation of a web enhancement that details a Half-Succubus "variant" of the standard half-fiend template, which can be found here: http://archive.wizards.com/default.asp?x=dnd/we/20060630x&page=3
