Biology

Succubi are female-looking, pale skinned demons with sharp teeths and 3 eyes but able to shapeshift. They drink male blood as foof, wich makes them similiar to the Vladeks. Also their origin is comparable, are they descendants of human people and ancient nymphs. They naturally feel the strong urge for male blood because the human part of their biology is decaying because of icompatibilities with dryadic existence. Aside, they're nearly immortal. This makes them also belonging to the undead races. To kill a succubus it has to be revealed in its natural form and then beheaded, or spiked in the heart, which is black. Also full moon light hurts succubi.

Origin

Once many attractive nymphs lived on the western continent and some of them had encounters to human beeings. Their natural charme and childlike curiosity led to some copulations with human males, which was strictly forbidden by the gods. Nethertheless, some nymphs used their magical powers to create new ways of life and got half-mortal children in love. These beautiful and long-living creatures were hided from the gods. But somewhere while the demongod war the gods discovered their existence and punished the human and dryad parents and banned the offsprings. A few escaped and joined the armies of the demongods to save their own existence. The demongodess Orphelia became their new mother and while influenced by demonic magic and godly marks of sins, all succubus transformed into deadly monsters. Their race is united in hate for the gods and all humans who didn't care for their halfbreed descendants.

Behaviour/Culture

Today, the succubi follow Orphelia who saved them from the gods and humans but act on free will. Their natural urge for male blood forces them to seduce human and to eat the victims while it's sleeping. As revenge to their long-died fathers for their lonely life they enjoy sadistic sexual games before killing the prey. To the human eye, succubi appear as attractive woman. Once fallen under their lovely spell, a male can't save himself alone anymore. Just before murdering, msotly while the male is sleeping, the monster reveal its real face. Most succubi travel through the land in small groups of about 3-6 women.

Mythology

Because of their sexual aspect, the succubi myths are often used by human churches to warn about consequences of sins against the gods and/or the church. Every year in the Middle Kingdom about 20 young girls with dubious behaviour get burned by clerics after beeing accused of beeing a succubus. Most of them had sex before marriage or just disagreed with their fathers too often.
