The planet was colonized generations before the start of the Galactic Civil War. Its residents believed strongly in a peaceful existence until it was forcibly conquered by the Empire shortly before the destruction of the first Death Star. The planet was heavily damaged by the ongoing war.
Crondre was the site of a diversionary attack by the forces of Grand AdmiralThrawn, whose real target was Ukio, during his campaign against the New Republic.
The PC game Star Wars: Rebellion mistakenly places Crondre in the Jospro sector of the Outer Rim Territories. Additionally, Rebellion's in-game encyclopedia entry for Crondre describes the planet as having once been beautiful before being ravaged from its involvement in the Galactic Civil War. This seems contradictory to its description as an icy world in the novel The Last Command.
