Water Worlds

Water worlds are planetary bodies in which the majority of the surface is covered in water (or ice). Water worlds are uncommon in the galaxy. When found within more moderate orbits, however, they have a higher chance of having life evolve on them. Many of the advanced races' homeworlds are water worlds, including Earth.

Water worlds typically are rich is base metals, though rare deposits of radioactive and corrosive metals can sometimes be found on the more degenerate water worlds.
