The Mid Worlds are an political/astrographical region located within the Terran Federation.

Many of these worlds are located in star systems within 35-75 light years from Earth.

Settled during the Great Exodus, many Mid Worlds first served as trade posts, Midway colonies and mining colonies to help the exploration following the Fourth Badoon War. As time went on, many of these colonies became an integral part of the Terran Federation's economy as well as prosperous melting pots. Some of the most prosperous include colonies in the Antares and Rigel systems.
