During the conflict known as the Yuuzhan Vong War, specifically sometime in the period spanning from 25 ABY to 26 ABY, the Yuuzhan Vong launched an attack against Kligson's Moon.
Kligson's Moon, otherwise known as Droid World, functioned as a mobile space station where Kligson, a cyborg, resided together with the numerous droids he had saved. Because of its advanced technological state, the technophobic Yuuzhan Vong selected it as a target.
Nevertheless, the Iron Knights successfully defended against the Yuuzhan Vong, forcing them to retreat.
