Succubi

The Succubi are an all-female race of lust-driven humanoids who can drain life energy from beings vulnerable to sexual magic.

Biology
They are mostly human-like, but usually have pointed ears, horns, bat-like wings, and spaded tails. Despite this, succubi are not demons. Compared to humans, they reproduce very quickly, but live much shorter. Succubi reproduction is... unusual. While they give birth the usual way, succubi conceive only when they want to. A male partner is required, but their seed can be absorbed anywhere. The child is always a succubus, but reflects the father to some degree - how much exactly is a subject of dispute among the succubi. Orcs are able to impregnate succubi, but they appear to have no influence at all on the children, and while this allows for population maintenance, succubi prefer to seek partners among the other races. Succubi who use "futa spells" to grow penises are able to have children with other succubi, but not with any other race's females, for unknown reasons. Succubi reach maturity and age faster than humans. The average lifespan is just about 40 years, with rare exceptions: Riala is legendary among the succubi on Arclent for her age and power (the explanation of this anomaly is revealed at the end of Chapter 3). While they don't age the same way humans do, succubi do start to feel a decline in power after around the age of 25, which has psychological consequences similar to the mid-life crisis in humans. Because of the different rate of aging, all succubus characters on the wiki have both their chronological age and the equivalent human age listed in on their pages. Succubi don't need sexual energy to live, but they need it to thrive. Like humans, they can survive only on food and water, but this is detrimental to their well-being: among other things, their hair gets dull and wings go limp. While it is generally assumed that succubi consume sexual energy by eating semen, it has been theorized that succubi can feed off of sex itself. Additionally, succubi can forgo sleep if they are sexually charged, but they can't do so indefinitely. There is believed to be some connection between succubus appearance and their power and status. Black hair is traditionally associated with elite succubi, though there are exceptions. The librarian succubus of the Orgasmic Palace attributes the connection at least in part on social conditioning. Most succubi have white hair, a smaller number - green, and even a smaller number - black and other colors. A succubus with a natural bright pink hair is unheard of, though she's "probably perfectly normal". During the Gathering, we have the opportunity to discover that there are various different phenotypes like the Ghenalese Succubi or Draconian Succubi during the Succubus Hunt or the succubus meeting. Lamias also identify themselves as part of the succubi race, but they face discrimination by other parts of succubi society. .

Culture
Succubus culture revolves around sex. Sex is used to worship, to raise children, and form relationships with others. According to Nalili, kids who don't have sex with their parents grow up to be weirdos. Because succubi almost always seem willing to have sex, succubi also seem to have trouble understanding consent. Their society is also very inefficient, because most succubi would rather work in a brothel or as a soldier instead of doing needed office work. Most succubi appear to be bisexual; in general, they are easily and often aroused, always ready to jump whoever they find attractive. This causes conflict with humans since succubus culture don’t really teach the a concept of consent. Despite using lust in combat on everyone possible, they do have personal preferences in their choice of partners.

Politics
Along with orcs, succubi tend to be ruled by Incubus Kings, though independent groups do exist. Unlike orcs, succubi tend to be about as intelligent as humans, and can have quite varied characters and worldviews. Like humans, succubi can be found all over the world, and they are the dominant population on Renthnor. In the countries where succubi are the majority, they are usually ruled by Incubus Kings. In other countries, succubi use illusion magic to disguise themselves as locals in order to feed off the sexual energy of locals. The exception would be the multi-ethnic Ghenalon, where succubi live in peace with other races.

Religion
The religious beliefs of the succubi are primarily centered around the mythical figure of the Lustlord, acknowledged as the same being depicted in Ivalan theology. The form these beliefs take varies between the different succubus societies.

Many succubi have also found themselves drawn to the the Church of Ivala. However most tend to prefer a version of the church that is less restrictive on sex.

Lamias
Lamias are a subspecies of succubus with serpentine lower bodies, no wings, and sometimes snakes in place of hair. In other respects, they are generally similar to normal succubi. Lamias are used as guards and other "muscle" roles, but are rare in many parts of succubus society. Some of this is for practical reasons, as they can't sit on normal chairs, climb stairs, walk easily in narrow spaces, and other actions common to humanoids. However, much of it is because lamias tend to be discriminated against, even by other succubi (at least in the Orgasmic Empire and Arclent).

Unsuccubi
During the Third Arclent War, a new sub-type of succubi appeared. The Unsuccubi were the Incubus King's answer to divine anti-sex magic, being totally immune to its effects, as their sexuality had been stripped from their souls by the Incubus King. As succubi's souls are inherently intertwined with their sexuality, the process of converting them to Unsuccubi rendered them little more than rampaging feral monsters who felt constant agony. This meant they had no sense of loyalty to any causes, although they would not attack each other. Their strength varied, but the presence of their broken souls unnerved those who could feel them. Some whose transformations were incomplete were restored by Simon (although there were some who could not be saved), although they bear permanent scars of their ordeal. Recovered Unsuccubi share a special bond with Simon, leading some of them to choose to join his palace guard. Although their experiences have separated them from the rest of the succubi population, their unique traits have actually made many of them more attractive to other succubi.
