Erida

History: All we know about Erida is that she is the spirit of the dead woman. Her death was caused after giving birth to a child. Her child is still alive. One day a lilltle teenage girl called Megara got lucky and summoned a dark spirit of a dead woman. The spirit called herself Erida. Day by day they've met in real life and in Megara's dreams. They spent a lot of time with each other becoming friends until one day Megara got sick and lost her consciousness almoust for two days because of the too powerful spell she created. By the help of an unbelievably expensive potion and a mother's love, Meg was brought back to live. She decided to take a break from magic for a while and told Eris to leave, because Megara didn't want to exterminate her. Eris got mad and decided to do everything to make her "little friend" to be with her again. She thought that the main reason Megara left her, was her mother, so the solution to this problem seemed simple. She just killed Hera. Later that night Eris came to visit Megara's dream again. She literally told her about what she did. Erida didn't understand why her mistress were crying, but it was too late for both of them. Meg brought Eris back to the underworld.
