The station was little more than a generator spindle with cargo boxes and bits of old transports welded together. In the early days when ships struggled to reach warp two and most journeys stretched into months, Xand Depot was used by these ships to make repairs and provide crews with shore leaves.
Even at the height of its popularity, Xand Depot was very much a cobbled together affair. There were several accidents which led to loss of life in addition to pirates operating in the area. As vessels became faster, the place's short comings led to Xand Depot being abandoned and forgotten.
In the late 23rd century the place was rediscovered by the Kriosian terrorist group The Thorn. The group was able to restore power and life support to parts of the station, however a good part of the station was open to space. (TOS novel: Cast No Shadow)
