The throne room of the Final Order's emperor and leader of the Sith Eternal Sith cult, Darth Sidious, was located at the Sith Citadel of Exegol. It housed the ancient Throne of the Sith, which the Dark Lord of the Sith offered to both Kylo Ren and Rey, two promising successors. Opposite to the throne was an amphitheater that could hold hundreds of Sith cultists. Between these two structures laid a wide space upon which Darth Sidious' Sovereign Protectors stood guard.
