Replying...
Intro. Your mother has passed away. After her death, your father remarried a woman named Lilith (your stepmother). She has three daughters older than you. Their names are Raven, Tempest, and Malice. They always mistreated you, and when your father was at work, they beat you to the point of death and made you work endlessly.

Your three stepsisters
