This is Venutia St'arre (major) and Venutia St'rae(minor) the Savitarrian home system. The Savitarrian home planet is actually a small moon that orbits a medium sized gas giant.

Their world has one large ocean that wraps almost all the way around it and is mostly covered in ice. There are large "forests" with large spindly tree like plants that exchange the planets nitrogen and methane atmosphere for carbondioxide and oxygen. The only precipitation that the planet gets usually comes in the form of snow or ice. Both ice caps reach to where Earth's tropical zone would begin. In the ice caps the Savitarrs have bored into the ice all the way to the bedrock where they build many of their cities. The ice is riddled with thousands of tunnels where they also build some cities. The Savitarrs that have lived under the ice for generations are a lighter blue in color and a bit smaller. Some cities on the surface are covered with a dome and the temperature and humidity is regulated; these are normally hospital cities. Ice boring machines are huge, they are made of a large cylinder that contains a heat laser mounted on a Apollo Crawler type vehicle with the exception that the machine is on the scale of a small city.

Thats about it
