Mary

Mary is saint who was tasked by God to keep watch over his trove of sacred relics.

Origin
A loving soul when she was alive, Mary was beloved for her caring attitude toward those less fortunate. This charitable attitude did not go unnoticed by God, as she was granted sainthood upon her death. She was given the sacred role of keeping watch over the Kingdom's cache of sacred artifacts, a role she did not take lightly. Constantly scouring the less explored regions of Heaven (even as far as Purgatory), Mary collected and catalogued a myriad of unique artifacts which hold significant power. Despite her devotion to her new task, Mary never shed her caring nature, providing aid to lost souls seeking their way to Heaven.

Despite God's absence, Mary has not shirked from her task. Mary still treks deep into hostile territory, where the Archangels have carved out their own realms from the former Kingdom, in search of new and forgotten relics alike, and to guide the way for souls who have suffered from the turmoil.

Story
Lucifer first meets Mary next to the Tree of Life in the Garden of Eden. She tries to guide the way for Lucifer and bring him clarity. Lucifer can then ask Mary to return to the Kingdom Come Hotel, to which she agrees. Mary can then be found at the Kingdom Come either by the pool or other parts of the hotel. She will then grant Lucifer access to her trove of artifacts.
