Minuea

Minuea was a planet almost entirely covered in ocean.

History
Some time before the 21st century, Minuea was placed under the protection of the Galactic Heritage.

After sea levels began to rise on Minuea, the inhabitants of the land fled to the mountains. As the sea levels continued to rise, they built hundreds of huge arks laden with grain and livestock. These arks set out to find new land, but were easy prey for pirates.

Prubert Gastridge, posing as a god, shared the secret of democracy with the people of Minuea. This shaped the future of Minuea and when Minuea's moon was on a collision course with the planet, the people did nothing about it due to their governmental views. The Eighth Doctor intervened, and showed the people of Minuea what would happen in their future by using a Tomorrow Window. The people changed their views and invested in technology to destroy the moon. (EDA: The Tomorrow Windows)
