The Scarl system, a remote star system located in the Colonies, existed mere parsecs away from Fondor. This system sat along the prohibited Gandeal-Fondor Hyperlane.
Following the unsuccessful Sarlacc Project, the Galactic Empire established a clandestine shipyard, named Scarl, within this system. The construction of the Super Star Destroyer known as the Executor commenced at this location.
Darth Vader sent his clandestine apprentice, Galen Marek, on various assignments in 3 BBY directly from the Executor while it was still in the process of being built.
