Agrat Bat Mahlat, or just Agrat. Is another character I was working on, tho unlike Naamah I don't exactly have a model sheet with a back view.
In world building lore I have:
Agrat was a demon spawn that Lilith felt a bit of sympathy for, essentially influencing her to a more vampiric look of between bats and owls. She is more associated witih bad wind storms and bad tidings. She generally likes to scare mortals that being haunted by her via dancing on their roofs, making animal noises, just generally driving mortal bat shit insane.
