A foul seven-and-a-half foot tall winged humanoid creature with the face of a carrion bird, carapace plates and weird segmented legs like an ant, but bat wings? Flesh is decomposing. First encountered in the temple to Hastur below Iris Hill, whispering into Melisenn’s ear.
In Chapter 82, the creature was revealed to be a blood-sucker, and would fly into a rage when feating.
