Drogheda II is a cold ball of rock and ice. In times long past, it is likely that the planet had possessed an atmosphere, as fossilized remains of primitive plants and even small animals are occasionally found in the rock formations that cover significant areas of the planet not buried under the polar icecaps. If this is so, whatever befell the planet and stripped away its atmosphere must have happened early in the evolutionary journey of life, as no vertebrate fossils have yet been discovered.
Drogheda II's original colonists were actually refugees from the neighboring Nixor system, fleeing the onslaught of the Krath during the Great Sith War. With the other planets in the Drogheda system turning the refugee's ships away for fear of Krath reprisal, and with fuel running low, the convoy was forced to land on the only planet that could not turn them away - the previously unoccupied Drogheda II. The ships landed close together for mutual support and the engineers aboard linked the ships for better sharing of resources. Exploration of their new world led to the discovery of significant deposits of a chemical compound that could be refined into usable fuel, with some modification of the ship's engines. With this new power source secured, the exiled Nixoreans were able to construct hydroponics domes to supplement their dwindling food resources.
Over the course of several centuries, the exiles managed to form a thriving community, harvesting the resources available to build their society. The descendants of the original colonists originally had frosty relations with the inhabitants of the other planets in the system due to the initial antipathy with which their ancestors were greeted. Over the centuries, however, these tensions thawed, and the planet is now a part of the general harmony within the system. In recent times, domed cities have been established in many areas of the surface. The first city of ships, however, is carefully preserved as a testament to the will of those ancestral Nixoreans and a constant reminder to the current population that anything can be achieved with enough courage and determination.
