Outer expanse

"Now why did they separate [the outer expanse] from the outskirts? Its not like it contains more than a dozen colonies."

The outer expanse, often referred to as the third rim, was the furthermost ring of consistent Human expansion during the third millennium CE. A lack of regular garrison by the United Nations Space Command combined with relative safety against external threats allowed for a variety of insurgent groups to take root in the expanse.
