The main objective on the Mission to Rigel III was to investigate the Tkon ruins and investigate the energy from the ruins. The Delta Squad was sent on this mission.
Once they were in the ruins, they couldn't detect any Tkon energy, however they did find alot of Orion Pirate mercenaries and assault bots. Eventually, they came upon the base entrance to find it locked, however, they found a secret passageway, which was probably how the Rebellion got into the base. However, they found the base heavily guarded by Orion Pirate forces.
In the base, they overheard a naddist on a communicator with a person named Calvot, about three bases on Rakal D, Amleth Prime and Loval, all home to human colonies. Making their way through the corridors, the team encounters a human Seijin named Calvot. Calvot challenged Tilanna to a duel, in which Tilanna emerged victorious, as Calvot fled through a hole in the wall, and fled to his ship.
After completing the mission, the team was promoted to a team of privates.
