Beta Andreas
Beta Andreas:
A star very similar to the one that the human homeworld Earth orbits.  With little fluctuation in its activity, it is a great contender for a habitable system.  However, it has not been settled by humans yet, and is considered on the fringe of human exploration.
As yet unnamed due to its lack of traffic or interest from any corporations, Beta Andreas is actually perfect for human life, but would be a hassle to settle.  However, some scientific communities have shown interest, particularly when a legend eluded to the existence of something called the Gateway to Eternity.

The ancient cities deep in the planet's jungles probably have the answers, as this was once a home planet to the race called the Raginors.
