This animated series follows the adventures of two dragon slayers in a strange future world in which pieces of land float like islands in midair, linked by a few rickety bridges. Each island has its own medieval culture, climate and geography, and its own mutant monsters, which the people call dragons. Our heroes are Lian Chu, a brawny type who is an expert with a sword, and Gwizdo, who is brainy but cowardly. They also have a tiny blue pet dragon named Hector.
