Unidentified planet (Exim Panshard)

A planet was ruled by the Sith Lord Viceroy Exim Panshard prior to his death. By 21 ABY, the planet had become long forgotten and the viceroy's tyrannical reign of the planet was told in legends. After traveling to the asteroid known as Kiza's world, Jedi Master Luke Skywalker came across the mask of Viceroy Exim Panshard that was in the possession of Kiza. Panshard's spirit, which lived on in the mask, showed Skywalker visions of his rule of the planet.
