The planet entered an ice age in 5,000 BBY. Glaciers covered the normally-warm equatorial regions of the planet, while solid ice locked the poles in perpetual winter. In order to survive, the Chiss built energy-efficient warrens beneath the ice, as close to the warmth of the inner planet as possible, with underground carriage travel routes to connect the various underground sections of Csilla. The iceways were bored through the bedrock of the planet, so that they were unaffected by the shifting ice found on the planet's surface.
