Island Clouds are a special type of cloud. They are fluffy, but dense enough to carry all kinds of things. They form islands in the sky seas. Island Clouds, as well as Sea Clouds, are created when a compound in Seastone called "pyrobloin" is ejected into the air by volcanic eruptions and comes in contact with water vapors. The density of the water vapors determines whether Sea Cloud or Island Cloud will be created. Both these types of clouds are not normally able to survive on the Blue Sea.
