Elements of Harmony

Description
The Elements of Harmony are six supernatural artifacts representing subjective aspects of harmony. They are arguably the most powerful force in Equestria. Though the extent of their power is largely unspecified, it is revealed in "Princess Twilight Sparkle - Part 2" that the elements were taken from the Tree of Harmony. However, doing so had the potential to release the Everfree Forest and destroy Equestria. Each artifact represents an element of friendship and can presumably only work if wielded by one who possesses the corresponding trait, and only if all six are used in conjunction. They have been wielded on rare occasions, particularly during events marked by danger and anarchy as a last resort to restore and enforce the balance of peace and order. However, the effects of their use are generally temporary and non-lethal, usually a form of banishment or imprisonment.
