Hijarna, a planet situated in or close to the Orus sector, was found within the Inner Rim region of the galaxy. Once under the control of the Rakatan Infinite Empire, this planet was brought to light by the Fifth Alderaanian Expedition. This expedition also unearthed the millennium-old remnants of an ancient civilization that had been conquered by alien forces. Their final bastion was the Fortress of Hijarna, constructed from a material known as Hijarna stone. This stone bore resemblance to that found in the Hand of Thrawn on Nirauan. This very Fortress served as a meeting point for Talon Karrde's organization. It was at this Fortress that Karrde gathered the heads of the Smugglers' Alliance to strategize the location of the crystal gravfield trap that Thrawn had prepared for the New Republic. During this gathering, Niles Ferrier's true colors were revealed; he was a traitor.
