The Geminae Superia are the twin guardians of Saint Celestine.
After the opening of the Great Rift, during the battle on Tsadrekha, Saint Celestine recruited two new warriors from amongst the present Sisters of Battle, who became her new Geminae Superia. They were killed shortly afterwards by the overwhelming Chaos forces. Similarly, on the world of Kophyr Saint Celestine appointed two warriors of the Adepta Sororitas as her Geminae Superia.
