Simon (the ice king) got in Scandinavia and was warned against it but he ignored them and put it on his head and that made him go insane which caused his fiancée Betty to leave him, Simon then started to gradually change into the ice king we know. The crown gives him similar symptoms of Alzheimer/dementia but when he takes the crown off for a while his thoughts become more rationalised and sensible. And that's all I know about it. :3
I know the history of how Simon got it but what I'm asking where did the crown itself originally come from? Why is it so powerful? Why is it magical when it's clear Simon came from a world like ours? But more importantly... Who MADE the crown in the first place? Why does it's power drive him nuts? those are the kind of questions I'm asking about..
Oh sorry, I must have misread your question. I don't know the answer to your questions, there are many fan made theories but all I know is that it's from Scandinavia. Maybe there were insane ice wizards that infected the crown with their craziness
Only if she had something to keep her alive long enough for them to meet again like the Ice King did.. Then maybe she might've been her ... But no.. Doctor Princess is/was/is just one of the many princesses they made for Ice King to kidnap.. Though your comment made me remember that without the crown's magic Ice king become Simon.. Most interesting.. Makes me wonder if it's possible that Ice king's appearance is possibly a magical imprint of the guy who made the crown and we know it changes anyone who wears it long enough... Yes..That is just possible..
