The Raddan system, a star system, resided in both the Tharin sector and the Outer Rim Territories, specifically within the Slice region. This system is notable as the place of origin for the clothing item referred to as the Raddan vermin-killer's vest.
The reference book The Essential Atlas, authored by Daniel Wallace and Jason Fry and released in 2009, provided the initial mention of the Raddan system, pinpointing its location as grid square S-8.
