Lilu

The demonic servitor race that humans call incubus (male) or succubus (female) these demonic humanoids put out a pheromone that drives the opposite sexed humans into uncontrollable lust. 

They appear as beautiful demon winged humanoids with slit pupils and scaled arms below the elbow and bird claws.

They can cause paralysis with their kiss and can remain invisible to all creatures except the greater demons and angels. They are often used by demons to collect either sperm or eggs that can later be implanted in a breeder.

Lilu also can hold up to ten links, though they must visit them nightly to maintain those links through intercourse.

Lilu have the same type of immortality as a Greater Demon.
