While Luyten 726-8 has no planets to colonise, it's central location amongst the various inhabited sytems makes it the ideal stopping point for stellar traffic. As such the system became known as Crossroads early in the 23rd century.
In 2240 a large asteroid was hollowed out and Crossroads Station was built to accomodate the spacecraft passing through and to serve as a major trading outpost.
There are numerious smaller establishments throughout the system as well, however most of these are privately owned.
