Coralee

Coralee was a planet colonised by humans.

Astronomical Information
Coralee orbited two suns, making its nights short. It was half the size of Earth, though humans had no problems living on it. Its surface was 98% water, with the remaining land making a ring of islands around the equator. It had a set of rings, formed from a destroyed moon, which filled much of the sky at the equator.

History
The original inhabitants of Coralee were a violent species who worshiped war itself. Though they spent much of their time fighting each other, they would also attack neighbouring planets. Eventually, they created the Krill and sent them out to destroy. Eventually, the Krill were accidentally brought back to Coralee, and the inhabitants were killed before they could use their own weapons.

Many thousands of years later, Coralee was colonised by Earth. The population was mainly humans and dolphins, though Dreekans made a large portion of the population. (PROSE: Storm Harvest)
