Zone Zero referred to a section within Transport Station 5 on the planet Taris. This area became overrun with rakghouls during the times of the Cold War and the Galactic War. As the Galactic Republic initiated the resettlement of Taris, a survey team was dispatched to this zone, but only a single member made it back. A concealed vault containing an astrogation chart belonging to the crime lord Nok Drayen was situated within Zone Zero. Jicoln Cadera also maintained a camp in this location during the invasion of Taris.
