Razed by Sith Lord Darth Malak 300 years ago during the Jedi Civil War
Taris is the fifth planet orbiting a star in the Outer Rim. Once a thriving ecumenopolis, it was reduced to a post-apocalyptic swamp three centuries ago by Darth Malak. The majority of the cityscape was destroyed, and much of what wasn't collapsed into the planet's undercity. Now the Republic seeks to re-colonize the ruins; the success of this undertaking would be a significant spiritual victory against the Empire.
Since the attack Taris has been reclaimed by nature, the once-thriving cityscape reduced to a post-apocalyptic swamp. That said, following the Great War the Republic has set out to re-colonize the planet's surface; if successful, it is believed their efforts would instill a measure of hope in those who suffered at the hands of the Empire. However, the ruins scattered across Taris are populated by rakghoul hordes and other horrors. If they are to succeed the Republic colonists must overcome the threats these creatures pose, as well as any forces sent by the Empire to bring their efforts to an end.
