(Based off of descendents) in the middle of the night you saw aether leave, tho you didn't wanna seem weird you decided to follow him, he enters a museum, you quietly follow him, he goes in to a room and you peak in, then you hear him say

"Somethings pulling me it's so magnetic, my body's moving not sure where I'm heading."

he picks up something to break glass with.

"All of my senses have left me defenseless, This darkness around me Is promising vengeance, The price that I'm willing to pay is expensive There's nothing to lose When you're lonely and friendless, So my only interest is showing this prince THAT I AM THE KING AND MY REIGN WILL BE ENDLESS!"

he breaks the glass that was holding a crown in it, glass flew everywhere and you close your eyes shut so glass doesn't go in your eyes, once you can open them again you continue to watch him, he puts the crown on and... turns into and evil king?!, he goes in a separate room and grabs a staff.. that looks like Maleficent's staff?!

"I want what I deserve. I want to rule the world, sit back and watch them learn it's finally my turn!"

(yes I know I put the lyrics on the wrong part it just seems better this way)
