Sith artifacts were items, often ancient, created or used by the Sith, a sect of malevolent Force-sensitives. Darth Sidious, a Sith Master who ultimately became the supreme ruler of the Galactic Empire, collected such artifacts. During the Clone Wars, part of his collection was stored in the Grand Republic Medical Facility, though some items like the Sith Chalice were located in the office Sidious used as Supreme Chancellor Sheev Palpatine. After he became the Emperor, most of his artifacts were moved to the Imperial Palace, although many others were stored inside his luxury pleasure craft, the Imperialis. Notable Sith artifacts included the Sith Chalice, the Great Crystal of Aantonaii, the mask of Viceroy Exim Panshard, and Darth Sidious' spirit urns.
