query: Who built the Death Star?
passage: Death Star
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.
passage: Death Valley Railroad
The line was built by a separate company from Pacific Coast Borax Company, because they were struggling with financial issues at the time. Equipment and Heisler locomotive #2 "Francis" from the Pacific Coast Borax Company's old Borate and Daggett Railroad were used to build the Death Valley Railroad. After the line was completed, two 2-8-0 steam locomotives were bought from the Baldwin Locomotive Works to work the line and "Francis" was sold off.
