Level three represented a specific section within the Colossus' supertanker fuel depot. In 34 ABY, after the First Order started occupying the Colossus, a First Order stormtrooper, accompanied by a fellow stormtrooper, made a visit to Jarek Yeager's Repair Station. Their purpose was to interrogate Kazuda Xiono, a mechanic working there, as part of their inquiry concerning a pirate spy operating on the platform. Nevertheless, the commander and the trooper departed not long after receiving information through a comm indicating that the First Order had uncovered a potential clue on level three that warranted their attention.
The animated television show Star Wars Resistance featured level three in "The First Order Occupation," which was the fifteenth episode of its first season. This episode was broadcast on February 3, 2019.
