Ice King's Crown (Canon)/Omniversia999

"I see the visions always, whether or not I wear the crown. They tell me the secrets, the secrets of the ice and snow... that the power of the crown will save me with its frost. I don't know what this means, I'm really scared." --Simon Petrikov

Summary
The Ice Crown is the source of Ice King's powers, and has been bonded to Simon Petrikov for 1,000 years. Its history goes way far back before that. Originally, it was supposed to be a powerful wish-granting device.

The prehistoric Ice Element, Urgence Evergreen, set out to destroy the comet by making the crown, which would grant the deepest, truest wish of the one who wields in. In an unfortunate turn of events, his apprentice, Gunther, wished to be like him, and it permanently bound his wish to it just as the comet wiped out the dinosaurs.

It went onto a variety of hosts, and eventually got into the hands of Simon Pertikov, who used his power to survive the nuclear war. However, he went insane and became the Ice King for 1,000 years. At the end of the series, however, when they were being digested by GOLB, the crown reset, and Betty used its magic to merge herself with GOLB, creating a new being in the process.

The Ice Crown plopped onto the ground as soon as the fusion left, and it fell right into the hands of the Ice King's personal servant: Gunter, who wished to become the Ice Thing. The crown is now fused with Orgalorg and likely will always be.
