Guy de Yoyo
The famous explorer Guy de Yoyo was a previous Kompt de Yoyo. He discovered the Disc's second-highest waterfall in the Year of the Revolving Crab. Of course, lots of dwarfs, trolls, native people, trappers, hunters, and the merely badly lost had discovered it on an almost daily basis for thousands of years. But they weren’t explorers and didn’t count.
