By far the largest island on the planet, the Erro make Serenity Isle their home. Almost completely inaccessible due to its southerly location, distance from the mainland, and often mountainous coasts, the Erro have lived in isolation here for generations. Because of its size and position, there are a number of different terrains and climate on the island, and it is also home to the largest lake in the world, Long Lake, which contains more water than the next six largest lakes combined.
