Bilbringi IV is a rather friendly planet, although cold and with some volcanoes that have not caused trouble for quite some time. The surface is largely covered with glaciers, but the gentle climate makes them easily traversable. Multiple areas with caves are scattered over the planet and offer a perfect study case for speleologists, taken into consideration that ample protection should be provided against any species that are known to inhabit these caves. In the southeast, a forest provides all the vegetation that exists on this planet, apart from subterranean plants that grow on the walls of the caves. The original rock layer is visible where the glaciers have retracted and they offer suitable sites to safely land on this planet and build possible dwellings for prolonged stay for most species.
