Background
This Nun was present in St. Mary's Convent in 1972 when Azazel identifies it as a portal to Lucifer's Cage. After her death during Azazel's slaughter of eight nuns, she is used as a channel for Lucifer to communicate with Azazel. Through her, Lucifer instructs Azazel on the steps needed to release him, including the plan involving the Special Children.
