...and the person who coined dath ilan's cognate term of "corrigibility" some decades ago, still an Old Luminary on this subject in dath ilan despite her advanced age (for dath ilan), happens to be named Athpechya.
And dresses in doompunk. And has done so since she was seven years old.
And is a Law-Abiding Sociopath. Which is why Achpechya was turned down in her application for Keeper training despite the prediction that it wouldn't break her - Keepers can act like sociopaths if they choose, so there is no sane reason to train any actual sociopaths among themselves. Athpechya calmly reacted by training herself as a Keeper, and has gotten surprisingly far in it for winging everything, maybe halfway between first and second ranks in terms of capability boost.
As for why she's trusted to work in the World's Basement, Athpechya has made a compact with Civilization to render it her true services, and is by all secret prediction markets the sort of person whose keeping of that compact is more trustworthy than almost anyone else's alignment of underlying morality.
