Thaereian Intelligence functioned as the intelligence arm of the Thaereian military.
In the time period of the Clone Wars, Xirossk, an operative for Thaereian Intelligence, traveled through the space station known as Burnout while on a mission. There, he discovered the military was backing gladiatorial combats on the station with unwilling fighters. He observed the Heroes of Cularin present on the station and formulated a plan to notify them of the gladiator matches, hoping they would assist him in abandoning the military. Xirossk established communication with the heroes; however, Ta'Veel, a Defel agent working for Thaereian Intelligence, covertly observed their interaction and alerted his commanders.
