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. Demeter seems to pay no heed to rumors surrounding her daughter's disappearance, even doubting her brother Helios when he told her that Persephone journeyed to the Underworld. She left Olympus at some point in the past, and Demeter attempted to search for her in vain. 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. One of them, anyway.' Demeter will also confide in Zagreus regarding her daughter. In one conversation, Thanatos mentions that Zagreus has 'her eyes.

Little is known regarding Persephone's appearance, until Zagreus reaches Greece. 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. 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. She is known only from a flashback sequence triggered by Zagreus sleeping in his room, and from conversations between Zagreus and Nyx. Following her departure, Hades forbade all mentions of her in the House, and as such she remains a figure of mystery. Had she died, she would have returned to the House as he does via the River Styx. It is unknown why she left, or if she was successful in her escape, but she did not die.

She is Zagreus' birth mother, but has since left for the world above. She married Hades and was noted to be a stately, kind woman as the Queen of the Underworld. Persephone is the goddess of vegetation (particularly grain), and a daughter of Demeter.
