Like most star systems, the Empyrean System is named for the star at its
center.  Unlike most systems, that is not the Empyrean's only star.  Six other
stars orbit Empyrus, each with its own system of planets and moons.  Also
unlike the other two systems, the Empyrean System still has a sizable number
of planets and moons that have yet to be terraformed.

Because of its abundance of planets, the Empyrean System is the richest of
the three.  It is also home to the most megacorporations.  Ten of the sixteen
most powerful entities in known space make their home here.
