Canyon Crown

A Canyon Crown is the head of a victim who has been decapitated by Giza Glass. The Giza Glass doesn't entirely cut off a part of the human body, but instead when a body part is cut off, the victim can still control it and has no real body effects due to the nature of the glass. The part of the body that has been cut off will swell up and grow if not treated with vinegar, hence why Canyon Crowns appear in such a large size.

Wow, I really can't believe my aunt went to the Grand Canyon, got decapitated by some big-ass statue with a weird sword, and became a fucking Canyon Crown.
