The staff overseer who is supposed to hold one-on-ones with indentured NPCs like Milk.
Milk notes that she hasn't had a one-on-one with a floor supervisor in over fifty seasons, asking what the point would be. The absence is the clearest measure of how completely the dungeon's management has stopped tracking her, even as her Sustenance Pellets and Damien's Newsletter deliveries keep arriving. The neglect is also what has let her get away with her Announcement Muting Scroll and with sleeping through entire seasons inside the Calligraphy Guild.
The absent management contact whose fifty-season silence measures Milk's abandonment.
