Lah ' mu Lah ' mu was a ringed agrarian planet in the Raioballo sector of the Outer Rim Territories . Its small population of settlers included the Erso family , who relocated to Lah ' mu after the Clone Wars , and were ultimately tracked down by Director Orson Callan Krennic years later . Description . Lah ' mu was an inaccessible planet located in the Raioballo sector of the galaxy ' s Outer Rim Territories , far from major hyperspace route s . Its planetary ring s were primarily silica formed from the remains of one of the planet ' s ancient moon s , pulverized long before the Clone Wars . Lah ' mu retained one other natural satellite . The planet itself was lush and dark green in color , and its biosphere transformed iron into chlorophyll . The planet ' s crust , split numerous times during its early geographic life , was fertile and rich with minerals and soils brought to the surface during this turbulent period . Many of the minerals found within the soil , including zinc , chlorine , cobalt , nitrogen , and boron , rendered the groundwater unpleasant to drink , despite the presence of an abundant hydrosphere . Further , volcanic tephra contaminated the greenery . Verdant and tranquil , Lah ' mu ' s surface hosted mountain peaks and plateaus , including some volcano es , black sand beaches , saline seas , geysers , and farmlands . Settlers lived on the western hemisphere , particularly around the fertile lowlands . History . Lah ' mu was named from a Neimoidian word meaning " prosperity " . Early in its geographic life , Lah ' mu ' s crust split numerous times , bringing minerals and soils to the surface that would later be farmed by the planet ' s sparse settlers . Initially hosting several moon s , Lah ' mu gained a planetary ring after one ancient satellite was pulverized , its remaining material pulled into orbit to form silica rings that cast shadows across the planet ' s surface . Volcano es ejected tephra during this formative period , contaminating Lah ' mu ' s natural greenery , forcing later settlers to carefully sift the soil . During the last decades of the Galactic Republic , the Ministry of Economic Development encouraged citizens to relocate to worlds such as Lah ' mu in the Outer Rim Territories , and offered incentives such as land parcels for the development of homestead s . Although the effort was mismanaged and saw many worlds either sparsely populated or abandoned , Lah ' mu was deemed safe if otherwise forgotten . As of 13 BBY , Lah ' mu hosted fewer than five hundred settlers , occupying farmlands on the western hemisphere . Many of these individuals arrived on Lah ' mu seeking to avoid war ; among them were the Erso family , whose association with Orson Krennic during the Clone Wars forced them into hiding on the remote , inaccessible world . Galen and Lyra Erso chose to reside in a sixty - five hectare homestead on the planet ' s less popular eastern side , purchased with the assistance of Saw Gerrera . The Ersos grew crops and utilized Pretormin Environmental GX - 8 water vaporator s to distill water vapor from the air . Unfortunately for the family , Director Krennic ultimately tracked them down , and arrived on Lah ' mu to take Galen , Lyra , and their young daughter Jyn , with him to ensure the completion of his stalled Death Star project . Galen refused , and a brief firefight erupted in which Krennic was dealt a glancing blow and Lyra was shot dead . Krennic ' s death trooper s burned the homestead and took Galen into custody , while Jyn fled to the black gulch beyond the former homestead ' s edge . There , she secreted herself in a shelter beneath a hidden hatch camouflaged by an artificial rock . She was later rescued by Gerrera . Inhabitants . Lah ' mu was sparsely populated , home to under five hundred human settlers who lived on verdant , tranquil farmlands across the western hemisphere . Most of the population came to the planet to avoid the Clone Wars , through encouragement from the Republic Ministry of Economic Development . The planet had no known indigenous intelligent life .
