Liam quietly walked into the central hub, moving to one of the empty benches and sitting down with a contented sigh.  He stretched out a bit, leaning his head back and closing his eyes.  Here in the central hub, the air was a bit fresher, a bit cleaner.  His clothes were clearly those of a worker, made tough and resilient.  Despite that, they were sewn in several places, and were liberally covered in small oil stains.  His brown hair also had a few spots of oil, and one smudge stood out on his cheek.  The ID badge on his chest, however, had been cleaned long before he reached the public sections of the station.<br/><br/>As he sat there, Liam willed some of his stiff muscles to relax.  He usually worked third shift, but had been called in early when one of the lifts in the CNC's section had broken down.  Since he was one of the only people both skilled enough to fix it, and small enough to squeeze into the tight shaft, he had been brought in early in second shift to fix it.  Finally done, he had roughly four hours before he could get some sleep.  The small room he bunked in had four beds, and was used by twelve people.  It wouldn't be his turn to sleep until first shift.<br/><br/>Opening his brown eyes once more, he looked up at the dome above, idly wondering what people used to see when they looked up on Earth.
