What is "phonoi"

In Greek mythology, the Phonoi (, "murders"; singular: phonos, φόνος) were the male spirits of murder, killing, and slaughter. While their sisters, the Androktasiai ("manslaughters"), presided over the slaughter of battle, they were considered to be responsible for murder and killing outside the battlefield. They were sons of Eris, goddess of strife, through parthenogenesis.
