Tatsu/Lung/Ryo/Ryu

The Tatsu is a common term for a dragon in Japanese. They are thought to be descended from a primitive form of a three toed Chinese dragon. They are associated with the sea and rain and live in rivers or the sea. They give proper amounts of rain to those who properly appeased them, and cause droughts and whirlwinds when angered.
