The planet Paarin Minor, located in the Outer Rim and a Republic bastion, suffered an attack from the Confederacy of Independent Systems during the Clone Wars, specifically sometime in the period spanning from 22 to 19 BBY. To obscure themselves from the Separatist forces, the Republic clone troopers employed a weather-control machine to generate an artificial cloud cover over their location. Once the Confederate battleships came out of the clouds, the Republic forces initiated an assault, inflicting significant damage, which prompted the Confederates to withdraw swiftly. Later in the conflict, during the Battle of Murkhana, the Confederates attempted a comparable maneuver, but its effectiveness was diminished.
Dark Lord: The Rise of Darth Vader, a book penned by James Luceno, which was available on November 22, 2005, was the first instance where the Battle of Paarin Minor was referenced.
