In my world, there are... were... six magical artifacts that granted great power called the Elements of Harmony: Honestly, Loyalty, Kindness, Generosity, Laughter and Magic.

Princess Twilight and her friends - I'm pretty sure you know who they might be at this point - were holders of these items until she was forced to surrender them to revive the Tree of Harmony and later unlock the Rainbow Power the Chest of Harmony held.

...it sounds incredibly farfetched to someone like you, I'm sure.
