A demesne served as the game board for Shah-tezh. This concept was employed by Emperor Sheev Palpatine when elucidating the nature of the Galactic Empire to a youthful Gallius Rax, an event that occurred twenty-five years before the Battle of Jakku.
In accordance with the game's structure, every piece is intended to safeguard the Imperator; the game restarts if the Imperator is defeated. Similarly, if the Emperor were to die, the Empire would dissolve and restart through the Contingency, because those who served the Empire failed to protect their leader. Adhering to this framework, Counselor Gallius Rax, a title that may share its name with the Shah-tezh piece, urged Grand Admiral Rae Sloane to journey to the Eclipse, a Super Star Destroyer then navigating the Unknown Regions.
