Persephone

Persephone is the goddess of seasonal change and vegetation (particularly grain), and daughter of Demeter. She was the wife of Hades but has since left for the world above. She was noted to be a stately and kind woman in her time as Queen. She is Zagreus' birth mother. It is unknown why she left, or if she was successful in her escape, but she did not die. Nyx says that had she died, she would have returned to the House as Zagreus does via the River Styx. Following her departure, Hades forbade all mentions of her in the House, and as such she remains a figure of mystery. She is known only from a flashback sequence triggered by Zagreus sleeping in his room, and from conversations between Zagreus and Nyx. Her mother Demeter will also confide in Zagreus regarding her daughter. She reveals that Persephone's father was an ordinary mortal and a farmer, and that she called her Kore, although she later took on the name Persephone. She left her mother at some point in the past, and Demeter departed from Olympus in a vain attempt to search for her. Demeter seems to pay no heed to rumors surrounding her disappearance, even doubting her brother Helios when he told her that Persephone journeyed to the Underworld. On the other hand, Hades is unsympathetic to Zagreus' attempts to pry more information about his mother, although he does mention that she always despised the name Kore. Before the events of the game, nobody in the House except for Nyx and Hades themselves knew that Persephone was Zagreus' mother; by the start of the game, everyone in the House (sans Hypnos) has learned that this is the case. The Olympian gods are, however, still unaware of this fact at the story's start, and do not know Zagreus' true motives in escaping the Underworld. Little is known regarding Persephone's appearance, until Zagreus breaks out of the Underworld and reaches Greece. In one conversation, Thanatos mentions that Zagreus has "her eyes. One of them, anyway.", implying that Persephone has green eyes, since Zagreus' eyes are red and green, Hades' eyes are red, and Persephone's mother Demeter's eyes are green. This is proven to be correct when Zagreus meets his birth mother for the first time.
