Rondo is a planetary system orbiting a white/yellow F-class star.  The system lies in the Crux Constellation of the Acrux/Agena Region.

The primary planet of the Rondo System is a large water covered world. Various floating cities are spread across the vast ocean. Rondo was one of the first worlds to pioneer the technology of cities that float on water. Floating platforms are used as a base, buildings are then constructed on top of them.


The technology developed on Rondo has spread across the inner sphere.  This allows settlers to colonize water covered worlds, without having to build and maitain expensive orbital space habitats.
