One day, an orange dragon flew up to a red, flopping fish. "You'll never become anything great" judged the dragon. The fish flopped around in response. A year passed and the dragon returned. "You're still nothing great. How pitiful." judged the dragon once more. The fish still flopped around, but glew a bright, golden light. It levitates into the air in a bright ball of pure light and comes crashing down into the lake. The fish had turned into a red sea dragon, filled with nothing but pure rage. The sea dragon subjugated the dragon by entirely covering it with ice, freezing the dragon in the process. The sea deagon has become something great, but it was too great. It thrashes around, creates a storm, and deepens the lake. The dragon gave the lake its name: Lake of Rage.
