Grimwing

Grimwing is a level 75 ghoul flight master at Acherus: The Ebon Hold in the Eastern Plaguelands.

Female?
During WotLK beta, Grimwing used an Undead Female (Forsaken) model instead of the current model (s)he currently uses. It is possible that Grimwing is actually a female ghoul, or that the model's placeholder status no longer counts towards gender.
