The Hall of Imperial Register, also known as The Pit, was an archive on the Imperial capital Coruscant which stored Imperial records. It stored records which had been offloaded to backup on Imperial starships, navigation computers, offices, academies, and depots. These records included trajectory calculations, inventories, personnel records relating to Imperial Military affairs including Star Destroyers and Super Star Destroyers. The Pit was located at the edge of the Verity District, a well-fortified Imperial part of Coruscant. The Pits were serviced by several administrative droids.
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.
