Tiber Quent was an assassin who worked for the Empire. The assassin's goal was to eliminate as many Rebel agents as possible. Quent traveled to Ord Mynock disguised as an Imperial courier with a datapad that had information on it for Project Firestorm. He planned on using that as bait to get Rebels to expose themselves and be killed.
Quent was skilled in brewing poisons and carried a small poison kit that allowed him to create many different deadly substances. He was also skilled in the use of blasters.
