A brief engagement occurred within the confines of the Pleknok system. This involved a Boadil family exploratory team and two Paataatus warships. The survey vessel sustained damage during the confrontation; however, it successfully retreated to the Chiss Ascendancy. From there, they requested assistance from the Chiss Defense Force. Upon arrival, the Defense Force discovered the Paataatus conducting their own examination of the planet and subsequently triumphed over them.
This minor conflict unfolded nineteen years prior to the mission to Pleknok undertaken by Thrawn and Thrass', thereby establishing the event's occurrence in 38 BBY.
