Accompanying the blessed bier that bears the skeletal remains of Saint Katherine within her reliquary armour are six members of the Orders Pronatus. Each of these handpicked exemplars of the Adepta Sororitas embodies one of the canonised Matriarchs of the six original Orders:

Saint Katherine, Order of Our Martyred Lady
Saint Dominica, Order of the Ebon Chalice
Saint Mina, Order of the Bloody Rose
Saint Silvana, Order of the Argent Shroud
Saint Lucia, Order of the Valorous Heart
Saint Arabella, Order of the Sacred Rose
