Grange, an agrarian planet, existed within the Mid Rim Territories. This world served as the homeworld of Galen Erso; his presence there caught the eye of Republic Futures Program scouts operating in Grange's sector. In the era of the Clone Wars, Grange held significant strategic value due to its advantageous positioning relative to hyperspace routes leading to distant regions. Consequently, the Confederacy of Independent Systems mounted a siege against it in 21 BBY.
