That’s…actually not a bad way to tl;dr the legend of Nightmare Moon.

“The elder sister, being vastly wiser and more mature, put the Moon Princess on timeout, on an airless, waterless, uninhabited ball of rock floating through space.”
 
Ha Ha! Vastly wiser?! Well, this just proves that. What a great solution. Vastly wiser? Where did you even get such an idea?

“The Princess of the Sun went through the castle and scratched her sister’s face off of every painting she appeared in. The Princess of the Moon then threw an epic tantrum, screaming abuse at the Sun. The elder sister, being vastly wiser and more mature, put the Moon Princess on timeout, on an airless, waterless, uninhabited ball of rock floating through space. Legend says, however, on the day of the thousandth anniversary of her punishment, the Moon Princess will return to avenge herself on her sister, most likely starting with short-sheeting her bed and sticking her hoof in a bowl of warm water.”
