Hall of Imperial Register

In 5 ABY, Grand Admiral Rae Sloane visited the Pits to find records on the Imperial Navy's Star Destroyers and Super Star Destroyers. She discovered that a quarter of the Empire's Star Destroyers and that Emperor Sheev Palpatine's flagship, the Eclipse, had mysteriously disappeared. Sloane also discovered a photo which depicted a young boy named Gallius Rax among several Imperial officials including the Emperor, Grand Vizier Mas Amedda, and the military officers Wullf Yularen, Dodd Rancit, and Terrinald Screed.

During the Battle of Jakku, the Hall was the target of an attack by the leader of the 204th Imperial Fighter Wing Soran Keize in a modified TIE fighter. He felt that the information held there would be highly damaging to the soldiers of the Empire after the New Republic took over the galaxy, and that years of trials would hound former Imperials trying to live their lives. He was defeated in this effort by Yrica Quell and Kairos who had pursued him to Coruscant. After the Battle of Jakku, New Republic Intelligence gained access to the databases of the Hall, though it was estimated that it would take years to sift through the vast collection of information found there.

The Imperial Archives held a number of reference material used by the historian Beaumont Kin, including File: Naboo Blockade in the Seized Trade Federation Records section, File T271 in the Emperor Palpatine section, File: Plans for Preventative Measures in the Occupation of former Separatist Systems section, File PG004—Executive Order Codes for the Grand Army of the Republic in the Galactic Republic Military Operations section, and File: Directives and Responses in the Galactic Republic—Population Observation section. These sources were cited in Kin's The Rise and Fall of the Galactic Empire.
