The Elements of Harmony

he  Elements of Harmony  are six supernatural artifacts which are arguably the most powerful force in Equestria though the extent and nature of their power are largely unspecified. 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 are used together. They have been wielded on rare occasions, particularly during events marked by pandemonium and anarchy as a last resort to restore and enforce the balance of peace and order.

They are wielded by Twilight Sparkle, Pinkie Pie, Applejack, Rarity, Rainbow Dash and Fluttershy.

History in LOTM

The Grand Summer Season Trek

In this story the elements as well as five of the six welders were napped by Discord while he was working for Vilgax. Vilgax felt confident that nothing could stop him or his allies as soon as they were napped. THis was also believed by Liberty Belle who boasted about how Discord couldn't  make them lose. Discord, however had his own reasons for bringing them. Through the help of his partner Obodiah Stane, Discord managed to create the five elements of harmony in his own way, he made them lethal to the degree that would annhiate a person like that. When Rainbow Dash escaped, Discord and Stane were not stumped as they had a backup plan. Stane and Discord brainwashed the ponies and then used the elements for their plan to emilnate Vilgax when Knucles bested him. When Vilgax was defeated, Discord betrays him and annihaltshis planets and the alien's hard work. After, Discord put his ampled up elements of harmony to the test and used to destroy Vilgax and he suceeded. However Discord was foiled when the others were brought back to normal and put him into stone

The Multiuniversal War of Destiny

Before the story, Obodiah Stane learns about what is required to make them work. Stane then confirms his findings that the users of the elements must not do an ammoral thing with them be it kill someone, steal from someone or used for revenge. When Discord escaped through mapulating Eddy and with his double agent Ricardio, Obodiah tells Discord about his findings on the Elements. Discord reveals to Stane that was the plan to have Applejack, Pinkie Pie, Rarity and Fluttershy kill Vilgax under his control so they would lose connection to them and not the same way he did before. Discord even states to Stane that being turned to stone was because the elements could only be used one more time before they negate for good on the Ponies. So now that Obodiah and Discord's plan worked it going to make things much harder for Twilight Sparkle this time.
