Abyzou is a demon from Mediterranean and European folklore known for causing miscarriages and driving mothers to murder their own children out of jealousy, since the demon herself was infertile. The demon targets pregnant women, including Evy and Jessa, using psychological manipulation and supernatural influence to fulfill this twisted purpose. The recordings sent to the podcast serve as warnings and instruments of the demon's malevolent will.
