- "Lord Trioculus, are you aware that there are others who claim to be the new ruler of the Empire? I have been to the planet Gargon. There, Grand Admiral Grunger says he is our new leader. And he has a fleet of thirty star destroyers!"
- ―A member of the Royal Guard, to Trioculus after the Battle of Endor.
Grand Admiral Miltin Takel was from Gargon. Grand Admiral Josef Grunger aided Takel's second in command to patrol Gargon due to reports of albino-skinned marauders around 3 ABY. He betrayed the fellow Grand Admiral and took over the planet following the Battle of Endor. Despite an unsuccessful attempt by Takel to oust him, Grunger continued to use the planet as his headquarters, until he was killed at the Battle of Tralus in 5 ABY.
