- "Taris was once a city-world, home to a planetary metropolis. Three centuries ago, however, it was bombarded by the great Darth Malak and left a toxic ruin. The years since have not been kind to Taris, as vegetation and animal life struggle to gain a foothold in shattered skyscrapers and habitats. The Republic began to recolonize Taris less than a decade ago, aiming to make it into a symbol of Republic hope and steadfastness. In response, the Empire is mobilizing troops and beginning a full-scale assault. Early reports speak of fierce resistance from the Republic, as well as natural hazards in the form of wildlife and the mysterious “rakghoul plague.”"

Once a thriving ecumenopolis, three centuries ago Darth Malak reduced the world to a post-apocalyptic swamp. This orbital bombardment during the Jedi Civil War was one of the Sith Lord's attempts to ensure the death of Jedi Padawan Bastila Shan. Although Malak failed to kill his target, the planet was decimated. Most of the cityscape was destroyed; the structures that weren't obliterated gradually collapsed into the planet's Undercity. Since that time, Taris has been reclaimed by nature, creating a strange amalgam of ruined skyscrapers and wildlife.
Now the Republic seeks to re-colonize the ruins. The leadership hopes that success in this undertaking would be a significant spiritual victory against the Empire, instilling a measure of hope in those who have suffered throughout the Sith invasion. However, the ruins scattered across Taris are populated by rakghoul hordes and other horrors. If Republic colonists are to succeed in this pivotal effort, they must overcome local threats, as well as any forces sent by the Empire to undermine their efforts.

- "Taris was once a city-world like Coruscant. Three centuries ago, however, it was bombarded by the Sith Lord Darth Malak and left a toxic ruin. The years since have not been kind to Taris, as vegetation and animal life struggle to gain a foothold in the shattered skeleton of a planetary metropolis. The Republic began to recolonize Taris less than a decade ago, and has suffered innumerable setbacks–everything from pirate attacks to the strange “rakghoul plague.” Nonetheless, the reconstruction effort continues, its proponents determined to prove that the Empire can never truly destroy greatness."
