The Gortys Project is a project that was funded and developed by the Atlas corporation (before its bankruptcy) to locate Vaults across Pandora's surface, which culminated into the Gortys Core: a holographic map (and/or locator) of said Vaults.
Episode 1: Zer0 Sum
After Bossanova's death, Zer0 reports to Moxxi that the Gortys Core was nowhere to be found. Disturbances from the fight cause a section of the floor to collapse, resulting in the discovery of the Gortys Core and other unreleased Altas prototypes. Upon its reassembly, the Core began to hover and display a holographic image showing the location of Vaults across Pandora.
