Dreighton, a rocky planet in a desert region, was home to an Imperial facility. Underneath this facility, the Galactic Empire constructed an extensive system of pipelines and mining tunnels that stretched for kilometers under the surface.
While under attack from TIE fighters over the planet, Rookie One and Kirby received a message from the Corellia Star.
As they moved to investigate, they were first engaged by standard TIE Fighters close to Dreighton; shortly after the initial assault, TIE Phantoms materialized, disabling Rookie One's craft and obliterating Kirby's B-wing, leading them to believe they were safe.
With no other way to leave Dreighton, Rookie One infiltrated the Imperial facility, battling his way through until he reached the YT-1300 transport, the Corellia Star. He then fled the base by navigating through the mining tunnels and delivered the ship to the Alliance fleet.
