The Lime Shelf Island island is a tiny isle lying to the far south-west. A unique feature of this island is that it is entirely made up of limestone shelves layered upon themselves, hence the island's name. Encased with the limestone is a chest hidden by those who assumed that no-one would visit such a remote island. This island is under the Island Nations Federation.
