[[WMG: Lily's madness was due to her use of the mirrors]]
* Like [[Literature/HarryPotter Voldemort's Horcruxes]], Lily Weatherwax's power amplification of the mirrors sapped her sanity. Not to say that she was lovely ''before'', of course. (Seeing as, among other things, her briefly-mentioned backstory hints that she was TheVamp who, unlike [[EthicalSlut Nanny Ogg]], [[DoubleStandardRapeSciFi used magic]] [[ReallyGetsAround for her canoodling]]). But while the several passages mentioning the dangers of using two mirrors foreshadow her [[KarmicDeath Karmic]] [[AndIMustScream Not-Quite-Death]], they also suggest spiritual mutilation that was never expressly elaborated on. This mutilation took away all her humanity, leaving only equal parts TautologicalTemplar and SuperVillain.
** I believe this may be canon. Agnes's brief encounter with the dance room leaves her horrified in Discworld/{{Maskerade}}. She could feel herself being pulled out of herself.
