Summary
After the Barrier came down, Papyrus left on a trip to explore the surface. The plane went down. Sans went out to look for him. And then his plane went down. A fairly stupid story (that came to me in a dream the night after a bad bout of heat stroke) about a mysterious island populated by humans and monsters that never stopped living peacefully together.
