There's a vast ocean extending as far as the eye can see, then further still. Floating within this ocean is a small island. The island is covered in lush green grass and tall trees. The sky is clear and the sun beams down upon the island, embracing it with familiar warmth.

At the center of the island lies a dark ravine, splitting the island in two. At the very center of the ravine is a wooden bridge that connects these two sides across the darkness below.

Upon this island there are twelve men and twelve horses. The men ride their horses valiantly across the bridge, charging headfirst into unknown land. Terra incognita. When night falls, the men and horses sleep. The darkness of the ravine spreads out across the island and causes the men to forget about the bridge. In the morning, they find a ravine, and then they find a bridge leading to unknown land. Terra incognita.
