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.
Found on desert planets, moisture vaporators were stationary devices that could collected moisture from even the driest of climes. Though they were stationary, they included programming that offered them a binary language that could be used to communicate with droids. On the desert planet of Tatooine, edible mushrooms frequently grew on the vaporators. For moisture farmers to make a living, they would need fields of moisture vaporators, and then security systems to protect them for those who might steal their water.
