From publisher blurb:
Glory and Ruin Amongst the Stars!
When Vandara was imprisoned, it left behind a wide variety of colonies, technologies, and peoples across the Aurin system. These forces have adapted since the Sundering, ushering in a new age of conflict and espionage across a war-ruined solar system. Discover the secrets of five scattered planets and the many moons that surround them! Gear up with over 30 new talents from the Technomancy Sphere (now with Wild Magic) and the brand-new high-octane Pilot Sphere (complete with Advanced Talents, Drawbacks, and new options for the Conscript and Prodigy classes)! Explore new facets of combat with 8 new archetypes and a variety of new high-tech mechanics, from the far-seeing Cosmic Prophet to the ever-resourceful Elite Commando to the endlessly versatile Gearmaster!
