Long ago is was part of a solar system but it was ejected for unknown reasons.

Geography
Sawej is a medium-sized terrestrial planet which is covered in a permanent sheet of ice which is many miles thick. This layer of ice keeps the interior warm by trapping most of the heat given off by the core inside the planet. This has led to a vast oceans under the ice which are heated by geothermal vents.

There is no atmosphere on Sawej and it is assumed it was lost during it's ejection.

The ecosystem of Sawej is made up of underwater creatures which feed on smaller creatures, who feed upon plankton-like creatures who survive off of geothermal vents at the ocean floor.
