After Twilight gets possessed by the magic from Human Twilight’s device. She begins finding magic in Ponyville. She merely says, “Friendship is… meaningless. I want to understand magic… even more.” Her destiny on spreading the magic of friendship completely collapsed, and she has taken full effect from the device’s “Midnight Magic”.
Its unlimited power

“…magic… what is true magic? I must… learn…everything.”
