Once a vast body of water which occupied most of the southern hemisphere of Ceti Alpha V, the Ocean of Dust became a sea of sand and blowing dust storms following the planet's unexpected transformation from class M to class K in 2268.

As the planet's mountain ranges run parallel to the ocean at the equator and south pole, there is little, if any, natural shelter in the region. (Decipher RPG module: Worlds)
