The Tears of Rist was an extremely powerful toxin that was used by the assassins of House Rist of Alderaan during the time of the Cold War. The elite Rists that used the poison were known to have camps in the wilderness along the Lowlands Road, Juran Crossroads and the Contested Valley in the Juran Mountains.
In the Cold War era, an official of the Sith Empire discovered that a mercenary working for House Thul had been killed by an assassin using the Tears of Rist. This led to a mission to collecting samples of the toxin.
