In Curse Of Strahd, Father Petrovich met The Pack, and he immediately respected them their piety and generosity. After they fed the orphanage at their own expense, he told the adventurers about the history of Saint Lugdana Andral; and that her remains, hidden in a secret cavity under the altar, Consecrated the church. He also told this secret to Yeska, his altar boy, which resulted in the bones being stolen by Milivoj Temesvari.
When the bones were recovered by the adventurers, Lucian assisted them in re-consecrating the church, as well as with storing Jarmo Maulgrave's petrified body under the altar along with the bones.
