This island is kind of a harder version of archipelago. It has three islands that are a bit bigger than a big archipelago island. Each island is a different biome with it's own temperature and weather conditions. The coldest island is always in the north and the warmest is in the south. Each island has a port leading to an island featuring it's biome. So jungle island has a jungle port, a savannah island has a savannah port, a swamp has a swamp port, etc.
