Wraith

A wraith was an undead creature born of evil and darkness, despising light and all living things.  They are incorporeal, being able to float through solid objects.  They could drain the life from living creatures. Wraiths were powerless in natural sunlight, appearing as a sinister, spectral figure robed in darkness. They have lightly glowing red eyes.

They are capable of speech, but loathe all living things.  They can be impressed into service and are often enslaved by the Darklords champions, though they are undependable followers.
