The Healing Hat is said in the episode to have been “made from the magic of the Savage Ages” and if you take a look at its appearance:



“Made from the magic” might be a euphemism for “made from the body parts of the practitioners of healing magic in said “Savage Age.”



Yet the weirdness and implied horror doesn’t stop there, oh no. Cause, remember, we know what the heads of the Nine Covens look like, from the banners outside Hexside.



The hands look to be gloved and banded but the color scheme is the same and we’ve only seen the bandages here and on the hand in the Healing Hat so far, so a correlation is possible!



But this implies some terrible things about how the covens and their relics actually came into being.
