The Eadu Energy Conversion Laboratory, also known as the Imperial kyber refinery, was a secluded Imperial research and development facility located on the planet Eadu. Guarded by the Eadu Deployment, the installation was where the development research was done for the Death Star's superlaser under the direction of Galen Erso as part of the Tarkin Initiative. A team of scientists at the complex undertook two interconnected projects: the fusing of kyber crystal shards into larger forms and the creation and redirection of a controlled chain reaction. Attached to the facility was a shuttle station where cargo shuttles delivered crystals for the team in specialized containers.
During Operation Fracture in 0 BBY, a Rebel squad consisting of Captain Cassian Andor, Jyn Erso, K-2SO, Bodhi Rook, Baze Malbus and Chirrut Îmwe traveled to the facility in a UT-60D U-wing starfighter/support craft to find Galen Erso. Director Orson Krennic arrived shortly after the Rebels in his Imperial shuttle to investigate suspicions of a Rebel sympathizer within the scientific ranks. After Erso revealed himself as the traitor, Krennic had his team executed by death troopers. The complex was then attacked by rebel starfighters, consisting of T-65B X-wing starfighters and BTL-A4 Y-wing assault starfighter/bombers from Blue Squadron, with the base's TIE/ln space superiority starfighters being dispatched to deal with the threat. During the battle, Erso was mortally wounded, dying in the arms of his daughter, Jyn. Afterwards the facility was destroyed.
