Spike leaned against a bookcase. "This part of the library confuses me. The sign says 'Myths and Legends.' But aren't all these things real?" He read aloud from a book with colorful pictures. "A thousand years ago, Nightmare Moon threatened to steal the sun, and plunge the world into eternal night."

Twilight said, "You're right! Nightmare Moon was a real alicorn gone bad."

Spike held up another book. "Grogar the Goat Monster."

"Based on real history! Most ponies have forgotten about the Evil Goat King. But the Grogarian Calendar of Doom predicts Grogar could someday return."

Spike touched a storybook. "How the Easter Bunny Ruined Spring Festival by Hiding Eggs Where Nopony Could Find Them, So Everyplace Would Smell Like Rotten Eggs."

Twilight's eyes bugged out as she stared at the giant bunny on the cover. "Ohmigosh! We have to put together a plan to TAKE THAT MONSTER DOWN!"

Story's Original Author's Note, in the Contest Itself

At that particular point in history, Grogar as Evil Goat King was an understandable misunderstanding, considering how many years had passed since anypony had last seen him.
