I was always curious about the crown, but figured it just kinda always existed (sometimes the mystery is better than the answer).
But this was a good episode. We get some insight as to why the crown makes you insane, and why it makes you look so different - turns out, you morph to look like its creator since the original Gunther wished to be like him.
Seems like that comet is where the Lich came from too (or at least it was controlled by him - given the green flames & horns).
Also calls back to Princess Bubblegum's line about all magic being advanced technology from the episode where she snuck into the wizard market.

Even though I’m not sure the crown needed the lore, and I don’t have the fondest memories of the comet arc, this episode itself is fun and memorable with an ending that still hits
