"When I was a novice [our goddess] visited us frequently, always in the same lovely aspect. But then she [Lucrezia] came to us in high distress..."

When I read "and the people went in terror of the strange other worldly servants the witch queen showed them", I straight up expected to see Geisterdamen. (A little disappointed actually...).

Either way, it seems to hint that even if Lucrezia is not herself a vessel of the Other, it seems she may have known one of the god-queens and either studied with her or tried to reverse engineer her work.

(And I still think Neolithic!Albia looks like a jacked Wilma Flintstone.)
