Water in its frozen form was known as ice, and in gaseous form was called water vapor, which formed crystals. Sometimes it would condense and fall as snow, sleet, or hail. Planets that experienced consistent ice included Csilla, Hoth, Mygeeto, Ilum, Rhen Var, Anteevy, Ota, Orto Plutonia, Ojom, Rekkiad, and Polus.
