Some point into the Imperial Era, the Alliance to Restore the Republic made use of the facility as a base until Galactic Empire discovered them. Associating it with rebel activity, the Empire bombarded the base, leaving it in ruins. Later, Darth Vader would be led to the base after visiting the Tomb of Padmé Amidala on Naboo. Discovering a Chroon-Tan B-Machine midwifery droid, his forensics droid assistant ZED-6-7 accessed her damaged memory bank. Vader watched the footage in anguish as his wife gave birth and eventually died.
The concept of the base on Polis Massa coming to be used by the Rebel Alliance was first seen in Star Wars Legends through the Star Wars: Battlefront II video game.
