A brilliant scientist, Galen Erso was coerced into using kyber crystals to enhance energy yields – work his friend Orson Krennic then weaponized to create the Death Star’s superlaser. Galen fled to remote Lah’mu with his family, but Krennic tracked him down and forced him to resume his work. Trapped, Galen seeks to build a fatal flaw into the Death Star and reveal it to the Alliance.

As director of Advanced Weapons Research for the Imperial military, Orson Krennic is obsessed with the completion of the long-delayed Death Star project. A cruel but brilliant man, Krennic has staked his reputation on the delivery of the functional battle station to the Emperor.

The Death Star began as a Geonosian design, but became operational after nearly two decades of work by a team of brilliant scientists sequestered on the rainswept world of Eadu. Led by a reluctant Galen Erso, the Death Star scientists seek to fuse kyber-crystal shards into larger structures and use those crystals to amplify energy into a stable beam powerful enough to destroy an entire planet.

The Death Star was the Empire’s ultimate weapon: a moon-sized space station with the ability to destroy an entire planet. But the Emperor and Imperial officers like Grand Moff Tarkin underestimated the tenacity of the Rebel Alliance, who refused to bow to this technological terror…

At the heart of every Jedi lightsaber is a kyber crystal found on several planets, most notably the icebound caves of Ilum. This crystal is attuned to the Force, and connected to a Jedi Knight on a deeply personal level. In this way, a lightsaber is an extension of a Jedi's Force awareness. Because Jedi let the Force guide their selection of the crystal, the vibration that the crystal creates in the lightsaber blade helps Jedi center themselves and find balance in the Force. In this way, a Jedi can center his or her attention beyond the distractions of combat. A lightsaber crystal is colorless until first attuned and connected to a Jedi -- at which times it glows either blue or green, or in some rare instances, another shade. From that point on, it retains that hue.

The Zeta-class shuttle is a versatile transport used by the Empire for military and civilian purposes, with a modular cargo pod housed below the holding bay and crew cabin. Bodhi Rook and K-2SO steal Shuttle SW-0608 from Eadu and then fly the craft to Scarif as part of the Rogue One raid.
