Over A Light-grey Rainbow

It was the 6th century, the time of when ancient forms of ponies existed, called Reli. They weren't your average pony, like Earth Ponies, Unicorns, Pegasi and Alicorns. They were much different. They had different types of power, like instead of a unicorn only having magic that suits its personality, the unicorn used an element. Each pony had a different element, some better than others, but there were six elements that everypony went scrambling for, and this is the tale of those six ponies.

"Everypony, one and all, it's time for the Summer Sun Celebration!" announced Princess Solis. Princess Celestia wasn't born yet, hence she was an Alicorn. Instead of Earth Ponies, Unicorns, Pegasi and Alicorns, they had Hearth Ponies, Ancicorns, Regasi and Curiocorns. Most ponies gathered around to the center of Thistleville to see the famous Curiocorn raise the summer sun.

"Where did Princess Mun go?" asked an orange Ancicorn.

"I heard Mun was banished to the moon!" replied an aqua Regasus.

"Everypony, please, calm down, Mun is safe, I assure you, now please, enjoy the setting of the night and raising of the day!"

Now, as you may have noticed, Solis was basically the Celestia of the 6th century, and Mun was the Luna. Solis kept the six elements, like Princess Celestia did before the Main 6 arrived. The six elements were Kindness, Generosity, Loyalty, Honesty, Laughter, and, the most powerful, Magic. It was said that the pony who received the element of Magic was qualified to become a Curiocorn, even if the pony was still little. Solis was frightened at the sound of there being a smudge of royalty to share, so she sent her sister, Mun, to the moon and kept the elements in a very safe dungeon, where they rusted and, as Solis hoped, lost their powers. As the Summer Sun Celebration was happening, a red Ancicorn was shut up tight in his bedroom, reading a book about the history of Thistleville.
