Hellhound (Demon)

Hellhounds are a kind of faerie creature, found in the Nevernever.

Description: Hellhounds are dog-like creatures, and have been seen taking the shape of numerous dog species, from Doberman to Chihuaha, although they seem to be made up entirely of shadow with the exception of glowing red eyes.Otherwise, they seem to share a similar physiology with actual dog.
Like normal dogs, Hellhounds have the ability to track down scents, though they do so remarkably well in the Nevernever. They are also fiercely loyal and easily trained. Like all other faerie creatures, hellhounds have an extreme vulnerability to cold iron.
