In an abandoned castle deep within the Everfree forest, the battle of Everlasting Night is almost to a close. Nightmare Moon is weakened and nearly defeated and Twilight has awakened the five Elements that her friends embody.

But there's just one problem. She can't find the sixth!

In a last-ditch effort, Twilight casts a powerful and ancient spell (from a library she technically wasn't allowed in) to summon the final Element from the next universe over. (They won't miss it, right?)

Unfortunately, her spell works a little too well and now she's swimming in Elements. Can she find the true Element of Harmony, or will she go mad trying to sift through so many that are just slightly 'not right'?
