The Silken Asteroids represented a cluster of asteroids located within a system under the jurisdiction of Moff Derliff. A battle transpired there during the Rebellion's initial phases.
Within the galactic region of Wild Space, at coordinates O-20, the Silken Asteroids existed as a field of asteroids situated in a system controlled by Moff Derliff of the Galactic Empire. During the early years of the Galactic Civil War, Moff Derliff governed the region encompassing the Silken Asteroids. These asteroids were rocky in nature and lacked water. Furthermore, Mynocks inhabited the asteroid field.
Around 2 BBY, Rebel General Jan Dodonna established a small base on an asteroid that possessed a meager atmosphere. However, Imperial-class Star Destroyers under Moff Derliff discovered it. The base's Z-95 Headhunters successfully repelled Derliff's first assault, prompting Dodonna to organize the base's forces to attack Derliff's base, ultimately driving the Imperials away.
The strategy guide for the video game Star Wars: Galactic Battlegrounds from 2001 was the first time the Silken Asteroids was mentioned. It appeared as the challenge mission for the Princess Leia campaign. The 2002 expansion pack, Clone Campaigns, also featured the mission and, consequently, the asteroid field.
