- "Sir, all the patrols are in. Still no…still no contact from Skywalker or Solo."
- ―Lieutenant Cal Alder, to Major Bren Derlin
Cal Alder was a human male who served as a lieutenant in the Alliance to Restore the Republic during the Galactic Civil War. Alder was an expert scout and often found himself among the first to be acquainted with the alien environs of frontier worlds. Because of the Alliance's severely limited resources, Alder's job was to look for ways to adept a new world's native ecology to the Rebel's needs.
