Notes:

Hildegard of Bingen—Medieval visionary that believed she saw visions of God's feminine side, Sophia.  In this story, Sophia is the master she refers to and a Mother Nature type figure.  The historical Hildegard was very sickly and detached all her life, hence the fictional one's appearance, demeanor, and physique.   

Shiriel, High Angel of Mercy—When the man kissed Shiriel's hand in the sign of the cross, she pardoned his sins.  This was how she relieved the sinners brought to her in Heaven.  In the end, the higher-ups thought she was abusing this power by pardoning everyone and slandered her into hiding and shame.
