The Geminae Superia are the twin guardians of Saint Celestine.
Previously known as Eleanor and Genevieve, they were both Canoness' of the Order of Our Martyred Lady. They were both killed by the Daemon Prince Urkanthos during the battle for Cadia in the 13th Black Crusade. Due to their bravery and faith, both were resurrected as Living Saints by Saint Celestine upon her arrival to Cadia and they serve as her champions.
After the opening of the Great Rift, during the battle on Tsadrekha, the Living Saint recruits two new warriors among the present Sisters of Battle, who become her new Geminae Superia but are killed shortly afterwards by the overwhelming Chaos forces.
