Succubus

Succubi are a female-only subrace of kazena which source their mana from sexual energy. Around 1/4 of the kazena women in Delvaruud are succubi. There are no physical differences between kazena and succubi, only their behavior, main source of mana and some physiology differs from them.

Behavior
Succubi are often way more openly sexual than other races, since they require it to use their magical powers. Succubi also seem to receive much more pleasure from sex, since it is not only mentally fulfilling, but physically as well. Though succubi require sex for their magical powers, they do not only have it only for practical purposes. Succubi often have sex just for pleasure as well, a few times a week is an usual frequency for most. The fact that succubi also have sex purely for pleasure explains the fact that some succubi are also known to engage in sex with females and other succubi, since succubi cannot harvest sexual energy from females.

Harvest
The main way of harvesting sexual energy by having sex with a male. During sex, sexual energy is slowly leeched from the harvested. When the harvested climaxes, a surge of sexual energy is released, this is the bulk of sexual energy to be harvested during sex. The semen released by the harvested also has an amount of sexual energy stored in it. Succubi often also extract this sexual energy, as it also deactivates the semen, preventing conception.

The yield of sexual energy harvest during sex depends on a few factors. The yield of a climax may be increased if the succubus and the harvested climax simultaneously. Another very important factor is age proximity. A succubus can only source a meaningful amount of sexual energy if the harvested is within 4 years of their age. An 18 year old succubus, for example, can source sexual energy from a subject between 14 and 22. If the subject is any older or younger, the sexual energy harvested is so little that it is no of use to the succubus. Yield is also dependant on the passion displayed during sex. Low or no passion severely reduces the yield, a lot of passion may considerably increase it.

When sexual energy is harvested from a subject, they often feel physically drained. The harvesting is quite taxing on the harvested and often leaves them exhausted. It often takes a while for a subject to recharge their sexual energy to the same point before a harvest. This recharge rate differs per race and species, humans often take about 30 hours to fully recharge their energy while kazena only take around 18 hours.

Benefits
Sexual energy benefits succubi in several ways. One of those is that it is the source of their mana, the power used in their spells is drawn from the sexual energy they store. It is almost completely equivalent to liquid mana. Another benefit is that storing any amount of sexual energy improves the general wellbeing of the succubus, keeping them more resiliant against disease, giving them more mental stability and increasing their sense of wellbeing and happiness.

Maturation
Since succubi have innate magical competence, both common sense and Delvaruudian religion dictate that succubi are to be granted access to their source of mana as soon as they are ready. Delvaruudian religion claims that succubi are ready to harvest sexual energy, and are therefore allowed to have sex, at the sacred age of 11, also known as the Age of Fruition. Before this age, succubi are taught how to control their sexual energy, how to effectively harvest sexual energy, how to prevent conception, religious ceremonies connected to sexual energy and some basic spells which can be practiced with sexual energy. Delvaruudian religion dictates that these teachings must start at age 9 at the very latest, but they often are taught around age 8.

Though succubi who have passed the Age of Fruition are ready to have sex, they don't often do because of general disinterest by boys their age. This often stays for the first few years after Fruition. Most young succubi get their sexual energy from semen from miscellaneous sources. Some young succubi who are eager to test their new magic even choose to harvest sexual energy from animals. This practice, although generally frowned upon in Delvaruudian culture, is often quite effective because of their age proximity. Young succubi who harvest sexual energy from animals often end up with more sexual energy than they can manage, causing them great distress. From the age of 14, mutual interest becomes more common and many succubi get deflowered around this time. They have gotten more religious teachings about their abilities by that time and are often also more mentally prepared to handle bigger amounts of sexual energy, amounts which are associated with direct sex.

Young succubi do not have many uses for their sexual powers yet, so they often do not require it as much as older succubi. They often only can get their hands on enough to receive the improvement of wellbeing and cast a few basic spells. Eager young succubi may take extreme measures to harvest sexual energy.

Procreation
Though succubi have a lot of sex, they are not concerned about getting pregnant. Succubi only ovulate once every 11 months in constrast to normal kazena women, who ovulate once every month. They have a way smaller window to get pregnant to begin with. On top of that, part of the religious upbringing of succubi is learning how to draw supplemental sexual energy from semen. Doing this deactivates the semen, making it unable to conceive with. If a succubus wishes to procreate, though, they can wait until they ovulate, copulate and let the sexual energy remain in the semen, keeping it active. They can even choose to imbue the semen with extra sexual energy, making it even more effective.

(Full-)succubus
When succubi procreate with a kazena man, there is a chance that their female offspring may become a succubus as well. The chance of a succubus bringing forth another succubus depends on the amount of sexual energy stored in the succubus at the time of conception. When at a low level, a succubus' offspring has about 5-10% chance to become a succubus. When the succubus' sexual energy level is saturated, the chance of their offspring becoming a succubus too is nearly 95%. During the gestation of a succubus, the baby uses up some sexual energy required for its creation. Just like a mother would "eat for two" during gestation, a succubus mother would have to gather sexual energy for two.

Half-succubus
When a succubus conceives a non-succubus, or officially "Half-succubus", female child with a kazena man, the child does inherit certain qualities of succubi. Half succubus women are most often also very sexual and have a very high libido. Just like succubi, they are also capable of storing a small amount of sexual energy. Therefore, they have the same general wellbeing advantages after sex. Many half-succubi are even able to control the sexual energy stored in semen in order to deactivate it, though most of them do require some training and education. Almost no half-succubi can store enough sexual energy to perform any other magic with it. Male succubus offspring is no different than other kazena males, except for a general hightened libido.

Jrane
If a succubus were to conceive a child with a man from a race other than kazena, the child may still inherit some traits of succubi. In this case, both boys and girls inherit these traits equally. These children almost always have a hightened libido, sometimes even to an obsessive degree. They also experience heightened sexual satisfaction like succubi, and they often get into a "low" if they do not have sex often. These mixed race children, known as the "Jrane", the delvarena word for impure, are not held to a high regard by most kazena and succubi. Most people from other races though often don't even know that someone is a Jrane. Jrane is the official term for these people, though it is often also used derogatorily. Most Jrane don't identify with this, but with their other part of their race.

Though succubi can pass on certain qualities and traits to their offspring, half succubi are not able to propagate these qualities and traits, nor can Jrane.

Intercultural relations
All of Varel knows of the existance of succubi. Some races and countries however do not appreciate them as much as others. Elves and zaiinaikan faeries have quite strict views on sex and find merely the idea of a succubus extremely offensive. Lya-ri'renadians on the other hand, often take a liking to succubi and kazena because of their mutual respect for sexual passion.
