Bvaneim widely recognize a third sex known as liminal sex, with associated gender roles. Though non-Bvanu cultures often consider liminal people intersex, Bvanu culture does not, as the Bvanu concept of endosex is trinary, including male, female, and liminal. The physiology described by this third sex is not exclusive to the Bvanu People (though it may or may not be more common; whether this is the case is highly speculative & hotly debated), it is just not as widely recognized outside Bvanu culture, and when it is, terminology besides liminal may be used.
Liminal individuals are much rarer than male or female ones, and occupy an honored status in Bvanu religious practice due to being seen as possessing a unique spiritual perspective outside binary male/female experiences. According to Bvanu tradition, the first human was created liminal before being split into male and female, and was made in the image of the Bvanu deity, who is often understood to be liminal in nature.
Liminal gender roles include the expectation of “relational balance” & spiritual leadership at the academy.
Sexual liminality may take the form of duality, absence, or fluidity: dual liminals have both male and female sexual organs, and are capable of impregnating & being impregnated, while absent liminals are unable to procreate, and fluid liminals can biologically shift between male, female, or dual/absent over time.
Transphobia within Bvanu communities is uncommon, especially against MTF/FTM trans identities. Where transphobia does appear, it usually centers around gender roles relating to liminal sex, either pressuring LTF/LTM (liminal-to-female/liminal-to-male) trans people who were ALAB (assigned liminal at birth) into liminal gender roles or refusing to allow liminal trans people who were AMAB/AFAB fulfill liminal roles. This discrimination is not condoned by Bvanu teachings, but is an emergent product of intersecting biases, and those doing it may not realize they are doing anything discriminatory. Nevertheless, it happens enough to be a problem.
