Aduba-6, situated on the Outer Rim of the galaxy within the Aduba system, represented the sixth and furthest planet. This world was characterized by its icy conditions and absence of life.
The planet housed the tomb belonging to an apprentice who served Vaius Antinus. During the era of the Cold War, Auselio Gann from the Sith Imperial Reclamation Service journeyed to this tomb. Prior to his departure for Aduba-6, Gann dispatched an encrypted communication to Talos Drellik, his apprentice. While inside the tomb, Gann encountered both Jedi and Sith attempting to unveil its mysteries, ultimately leading to his own entrapment as he redirected the tomb's defenses against them.
