The Dragons of Decagon

Once long ago, on a distant mountain that was called Dec-Agon, life was very, very different from what we humans know now. This mountain had ten huge sides to it. Each side had forests and large valleys, rivers, lakes, and each mountainside was beautiful in its own way—different but beautiful—except one. It was gray and murky and was always referred to as the dark side. Not much was known about this place except that it had a huge black castle in it and was guarded by fearsome beasts. This could possibly be why no one ever came out of there.
