Onyrō

Onyrōs (Idolon Capillilongis) are a species of idolonid sapient humanoids.

Physical Description
Onyrōs are smaller than their closest relatives, Banshees. They share all Idolonids' pale, dead-looking skin and ghastly eyelss face, though they usually keep the latter concelaed underneath their long black hair, which they bring back upon their face. Onryōs usually wear pale white tunics.

Lifestyle
Onyrōs are solitary creatures who dwell in dark, damp places, such as wells, forests, and, in some cases, cellars. They rarely socialize, and most of their contact with humans is through their hunting. Indeed, many Onyrōs are man-eaters who

Lifespan
Like Dementors, Onyrōs are functionally immortal, using magic to sustain their body throughout their life, and are able to regenerate any limbs they lose over a certain period of time, though decapitation will usually kill them for good.

Reproduction
Onyrō reproduction has never been witnessed first-hand, but most scholars theorize they do so in the same way as Dementors and Banshees (exuding a magical mist in which a new individual will slowly materialize).

Magic Absorption
Like Dementors and Banshees, Onyrōs have the ability of sucking in magic in a small radius. Though they seem unable to cast spells as such, they use this energy to sustain themselves, though they still need to eat conventional food. Their ability to sense magic is also believed to be what replaces their absent eyes.

Flight
Like Dementors, the strongest Onyrōs are capable of flight, an ability which they use to pounce on prey who outrun them in a normal chase. Onyrōs are generally too weak to use flight over long periods of time, but these hawk-like dives are a devastating weapon.

Fear Aura
Similar to Dementors' aura of despair, Onyrōs can influence sapient beings' emotions through their mere presence, projecting a feeling of fear and dread over their victims.

Classification
Onyrōs are classified as Non-Beings by the British Ministry of Magic, and given the threat level of XXXXX.
