History
In 13 BBY, a revolutionary named Saw Gerrera helped an Imperial defector named Galen Erso and his family find sanctuary on the remote planet of Lah'mu. The world was bleak, but serene, and Galen took up farming. The Imperials managed to track him down however, and advanced on the Erso homestead. Galen's wife, Lyra Erso, contacted Saw Gerrera, who then came to help. Galen was taken in by the Imperials, and Lyra was killed. Saw took charge over their young daughter, Jyn Erso.
