Leir II, Mya, is home to the Outsiders, a fringe society that rejects civilization. Leir was a corporate terraformed world which was abandoned after cultists staged an armed takover. Rather than retake the world it was decided to simply let sleeping dogs lie, cutting the group off and waiting for them to turn upon themselves. Surprisingly, this has not happened. The group stabilized into a thriving society very quickly and managed to fit in quite nicely on the world.
Miners operate unobstructed on the other two worlds in the system. Neither are terraformed and as a result require standard deliveries of machinery, oxygen, food and luxury supplies.
