Succubus

Succubi are an extremely dangerous race of demons that feed on the energy of mortals. They take on the form of beautiful women, with almost no imperfections on their body, to tempt men, elves and dwarves alike. They are separated into several Clans, each having their own role to play, but they are all led by the Royal Clan. They are driven by an insatiable hunger for energy, to allow them to keep their flawless form and, in some cases, even develop their bodies.

Their beauty and hunger however is matched only by their evil and sadistic nature. When capturing her prey, a succubus does not stop until it is wrung dry of energy, mummifying it in the process. While intercourse is certainly pleasurable, it quickly turns agonizing when they use their drain technique, which varies from clan to clan.

It should be noted that some succubi are clanless, in which case they are named Lesser Succubi. (Not to be confused with the Lesser Leaf Succubus which appears in Chapter 1) While they are the weakest among succubi, they still possess the same hunger as their superiors and the same potential to drain their victims. These succubi can also be under the protection of an Incubus, an extremely powerful demon rivaling even the Royal Clan. Some noteworthy succubi that are under the protection of an Incubus are Drita and Argeia.

Treatment of humans
They divide humanity into two casts: Haanaz and Ishkur

Haanaz are "pedigree" humans. The healthier women and the healthier males are isolated and kept for procreations in that world. They are oversee by a power Ogre or Alpha orc who is given a few of these humans to eat every few months as a reward.

Ishkur are humans that did not pass the "test". The guy was too short, too weak, not healthy, etc They are kept as slaves, constructing the succubi palaces and buildings in that world.

They are constantly invading worlds to get more supplies.

To feed well is another reason why succubi seek to advance in the hierarchy.
