Nasnas

The Nasnas is documented in the Arabian Nights and in the works of classical Arab geographers who placed them in the remote regions of Yemen and southern Arabia. They are described as the offspring of a shaitan djinn and a human — inheriting partial forms from both parents. Al-Qazwini (13th century) describes them as having one eye, one hand, one foot, and half a body, moving with extraordinary agility by hopping. They were said to speak and could interact with humans, but were dangerous.

In some accounts the Nasnas was considered a degenerated form of humanity — a reminder of the consequence of humans mixing with djinn. In others they were a distinct species, ancient and pre-existing, found only in the wilderness regions of southern Arabia.

Half a human body — literally bisected vertically. One eye, half a mouth, one arm, one leg, half a torso. Despite this, capable of rapid movement through leaping. Covered in fur or rough skin in some accounts. Their half-human faces are the most disturbing feature — recognizable as human but profoundly wrong.

Extraordinary speed and agility despite the half-body form. Can blend into rocky or desert terrain. Their touch was said to be deadly or at minimum debilitating. In some accounts they could speak and engage in conversation, making them more dangerous than a purely bestial threat.
