Soullex, a planetary body in the Wild Space region, existed as a planet within the Fardon system, situated close to the Oplovis sector. Following the events of the Battle of Tantive V, it became a fortified base, garrisoned to serve as the central command for Fleet Admiral Gaen Drommel. However, Drommel met his demise through treachery at the hands of Colonel Niovi, who then yielded the control of the Guardian to the New Republic forces.
