Thankfully though, this isn't a problem for the inhabitants of Thuban, the system's only inhabited world. Thuban is a manmade world, one of a number of engineered planets scattered across the Inner Sphere, shaped by the engineers of the old Star League. Originally an airless, radiation blasted rock the size of Terra's moon, its core has been hollowed out into a vast rock-enclosed cavern. The planet's spin was increased to provide an artificial out-is-down gravity, and its interior filled with a breathable atmosphere distilled from the native rock and ice. It is an inside out world, an enclosed environment entered through an airlock, a place where you can stand on the ground and look up at farmlands and forest, and small landlocked seas. The 'sun' is a thin, intensely radiant thread across the land-encircled sky, that literally pipes in light from the outside as required.
 During the FedCom Civil War, Allied forces struck at Thuban as part of the second thrust of Operation Scatter, a diversionary action designed to overload the LAAF's ability to respond. The Twenty-Third Arcturan Guards faced little resistance on Thuban itself, and quickly prepared to move on.
The Loyalist Eleventh Arcturan Guards arrived at Thuban too late to catch the bulk of the Twenty-Third, but were able to catch a combined arms battalion, left behind to effect repairs. The final battle, on the slopes of Scorpius Mons, was a bloody affair that cost both forces dearly and testified to the fratricidal nature of civil war.
