I have been to many worlds, some of them beautiful, some dangerous, and some both.  Capella is most definitely both.  There are some very interesting and energetic rare gases in the world’s atmosphere, and floating mining cities harvest them at very high altitudes.  The views from those heights are breathtaking.  Sunrises are beyond description.  And the local dragons are always happy to swoop in and snack on an inattentive vista watcher.
