This is the story I wrote for the Iron Author competition at Everfree NW. I haven't edited it, so there'll be a lot of mistakes. Also, as the time limit crept up on me, the ending is a bit lame. I hope you enjoy it anyway! (It also has not yet been named)

When Cadence spots King Sombra preparing for another attack, she calls for help from the Mane 6 and the elements of harmony. However, the elements have been hidden in the Canterlot Vault, a safe under Canterlot only accessible to Princess Celestia. Together with her friends, Twilight Sparkle must retrieve the elements and face her fear of failure.
