Caldera Cay is an island with a dormant volcano at its center. The volcano is dormant because of the actions of the Eruptodon dragon, who eats lava and magma. Possibly because of the rich soil base from volcanic ash and rock, the island is lush with vegetation. There are many stone structures on the island, built by the Defenders of the Wing. The Defenders of the Wings have also built a Dragon Ward - or dragon hospital - in their village and is considered the best in the whole of the Barbaric Archipelago.
