The Rennek palace was the seat of power of Zeta Magnus, self-anointed sovereign of the Dark Worlds, at the time of the Clone Wars. It was an opulent building, notably housing a jewel-encrusted throne of aurodium. In 22 BBY, Magnus stayed at the Rennek palace while an accelerated transgenic decoy of himself tried to take control of the planet Skye. When the decoy was ultimately defeated by three Jedi, Magnus' droid Blue-Tark returned to the palace to report to her master.
