When the Ersos decided to break with the Empire, Saw Gerrera facilitated the purchase of a 65-hectare farm on the eastern side of the distant planet Lah’mu. On this world far from the centers of power, Galen and his family have reinvented themselves as subsistence farmers, hoping to escape from Director Krennic and his hunters.

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.

A geologist with an extensive knowledge of crystals, Lyra Erso helped her husband Galen with his work before he became involved with Orson Krennic’s energy-enrichment project. Deeply suspicious of both Krennic and the Empire, Lyra believed in the Force and tried to share her faith with her daughter Jyn. When Krennic tracks the Ersos to Lah’mu, she risks everything to protect her family.

Putting behind a checkered past by lending her skills to a greater cause, Jyn Erso is impetuous, defiant, and eager to bring the battle to the Empire. Used to operating alone, she finds higher purpose by taking on a desperate mission for the Rebel Alliance.

A battered veteran of the Clone Wars as well as the ongoing rebellion against the Empire, Saw Gerrera leads a band of rebel extremists. Saw has lost much in his decades of combat, but occasional flashes of the charismatic and caring man he once was shine through his calloused exterior. Gerrera is bunkered on the ancient world of Jedha, coordinating a prolonged insurgency against the Imperial occupation. Saw’s ailing health has not withered his resolve to fight.

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.
