Kappa

Kappa are a mysterious subspecies of sincubus known for being reclusive and resistant to human integration. There are two distinct variants of kappa: the Northern kappa, and Eastern kappa.

Northern Kappa
Northern kappa appear as beautiful people and usually maintain long, lustrous hair. They appear to wear a crown or tiara, which is in fact a dish of sedative fluid which grows from the skull. These forest-dwelling sincubi usually eschew clothing and human-made luxuries.

Eastern Kappa
Shorter and less humanoid, Eastern kappa are built to survive in the forest. At a distance they appear human, but on closer inspection they appear more as a hairless animal. Like bears, Eastern kappa are able to run on all fours if it becomes necessary. They have slightly elongated face, and have the same fluid dish as their Northern counterparts.

Behaviour
Kappa prey on children by luring them away from their guardians and putting them asleep. Many children are excited to see a kappa or are curious not knowing what a kappa is, and follow it into out-of-the-way areas.

Once a kappa has lured its prey, the kappa will use the sedative fluid they produce on their head to calm the child into sleep, then absorb its potential energy over the course of 1-3 hours. Children are full of potential energy, and as such, a kappa only needs to feed once every few months, thus prolonging its legendary status.
