I've had this idea for awhile now... a crossover between Avatar the Last Airbender and My Little Pony! It's more of a story inspired by Avatar with lots of the show's lore in it. ///

Earth Pony. Pegasus. Unicorn. Alicorn.

Long ago, all four of the pony species lived together in harmony. But everything changed when Discord attacked. Only the two Alicorn sisters, Celestia and Luna, could stop them. But when the world needed them most, they vanished.

However, right before their disappearance, the two of them created a new kind of power: The Four Elements. The power of these elements were scattered around the pony realm, and now many ponies have the powers of water, air, earth, and fire. Using their newfound powers, the ponies began fighting against Discord's reign.

But the ponies are slowly losing hope that the war will end. The only way Discord will able to be fully defeated is with another Alicorn. but all of them have died.

or so they thought...
