The civilian freighter named Nova Crystal, a vessel of the Republic, operated during the era of the Clone Wars. This freighter engaged and eliminated the Traffic Interdiction Vessel known as TIV Z590/1 after incorrectly believing it to be a pirate ship, an event that occurred when it fired.
Because the TIV's assignment was classified, the fact that it was actually a Republic vessel remained concealed, and the captain of the Nova Crystal was celebrated by the Perlemian Traffic Control as a hero because of what he did.
