Cloud Giant

One particularly dangerous form of Giant is the Cloud Giant. Though their moniker seems to relate to air, they are by their nature Elemental beings of Water. They are very powerful wielders of magic, using their power to shape clouds into flying fortresses that they inhabit. They have absolute control of water in any form it may take and can even turn their own bodies, and those of their allies, into water. Many a band of travellers has been ambushed by a lone cloud wandering towards them in the sky, turning into sudden rainfall and an army ogres led by a Cloud Giant when it hits the ground. It has to be said, that these are the most intelligent of all giants, often surpassing even Storm Giants in intelligence. Do not mistake this newly found wit of theirs to be anything good; these beings are vicious killers through and through.
