One of the biggest sports in Caldera is Earthkin Clash. Earthkin Clash would be a battle of skill and strength between teams of Earthkin. The objective of the sport is to gain as much territory within the ring as possible within three minutes, or, alternatively, to drive the members of the opposing team over the edge of the ring. Because of Caldera's focus on strength and skill, this is a very popular sport and the best teams are held with high regard. Teams are only allowed three members on the court at a time, though teams can actually consist of multiple members, up to six. Some teams concentrate on specific types, while others go for a more mixed approach in developing a well balanced team. Unbeknownst to most, this is a hold over from the Pokemon Gym challenge of pre-Savior times.
