Loading dock 23 represented one of the bays belonging to the Colossus loading docks complex. During the events of 34 ABY, Resistance spy Kazuda Xiono narrowly avoided being assassinated by First Order operative Teroj Kee. Kee had instructed dock worker Glem to release Xiono's locker, with Xiono inside, plunging it into the waters surrounding Castilon. Despite this attempt, Xiono managed to get away.
The location of loading dock 23 was featured in the Star Wars Resistance episode "Dangerous Business," the thirteenth installment of its first season. This episode initially aired on the Disney Channel on January 20, 2019.
