Deep within an active volcano lies the fabled dragon breeding castle. The blazing temperatures provide the necessary environment for dragons to generate their coveted giant eggs. Here you may study the ancient dragon lineages, experiment with breeding your different dragons and spend Egg Tokens.
As this requires a great deal of lumber, the Breeding Castle is dependent on the Storage Hut's capacity to advance.
