Collects Angel: Illyria - Haunted (2010 IDW) #1-4.
Ancient. Alien. Illyria. Resurrected into the body of Fred Burkle (and burning all that she was in the process), Illyria remains one of the most mysterious creatures in the Angel-verse. But when she seeks out answers to her existence, she must make her way back to the Deeper Well, and confront her own demons, old and new.
