If the latest planet revealed for BioWare's Star Wars: The Old Republic sounds familiar, then you're mistaken, as Voss has never appeared anywhere in the Star Wars mythos.
Discovered by accident shortly after the Treaty of Coruscant, Voss is a strange alien world locked in conflict. War rages on the planet's surface between the tech-savvy Gormak and the Voss, whose mountain cities are protected by commandos and guided by Voss Mystics - Force users of incredible power who have no idea what the power they are wielding is called.
After a conflict between the Sith Empire and the Republic that ended with an entire fleet mysteriously disappearing, both sides decided to approach the Voss on a more diplomatic level, rather than force the issue.
It's easy to replicate existing locations - building new ones is hard. It looks like BioWare has the task well in hand.
