Lydia Iremia was an earth genasi healer who lived in the third century in the waning days of Cor Sol Orbis’ exarchy. Travelling from the distant lands of Montanum, Lydia set out to aid the denizens of Madanau after its perilous arrival on Fio. There she met Cor Sol Orbis, who was trying to convince Madanau to accept aid from the Church of Caelum. Sensing Cor’s intent to be benevolent, Lydia convinced the people to accept the Church’s offer and an embassy was constructed to facilitate the healing of Madanau’s wounds.
When Cor Sol Orbis became ill, Lydia offered her services as nurse to the ailing Exarch and the pair promptly fell in love. They married just before Cor’s death in 213 PO. It is believed that Lydia would sing a particular song to Cor at his bedside. Though commonly known as Saint Lydia’s Song, the song’s true title and composer are unknown. She would not become recognised as a saint until after the exarchy of Rex Sol Orbis, conqueror of Atada and Atado.
