The Explorer Corps refers to the many explorers dispersed throughout El Nido to study the Dragon God and other creatures and artifacts of myth and lore. They poked their nose in every nook and cranny of the archipelago, theorizing about the use of Elements and Dragonian technology, while always keeping an eye out for the Frozen Flame. They often carried Explosives and Safety Gear in order to traverse the more dangerous and inaccessible areas of the land. The actual teams were usually composed of a daring captain and several assistants. Toma XIV and Ash were among the explorers; specifically, they investigated the presence of the Black Dragon's nightmare in Marbule of Home World.
