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.
