Hijarna
this decaying world was discovered by the Fifth Alderaanian Expedition, during the Expansionist Period of the Old Republic. The Alderaanians found only the remains of a civilization on Hijarna, and all data pointed to the fact that it had been abandoned more than a millennia before. The world was the site of a huge fortress made from a substance that became known as Hijarna stone, since it was unique in the galaxy. The stone from which the fortress was build was nearly indestructible, and could absorb turbolaser fire like a sponge. Similar stone was found in the construction of the Hand of Thrawn compound on Nirauan, several years later. Kaarde chose to gather the budding Smuggler's Alliance there, to discuss plans to locate a crystal gravfield trap for the New Republic. Mazzic brings two rigged starships there, at Thrawn's command. It is also the place where the smuggler Niles Ferrier slips up and admits to his involvement in the attack on the smugglers at Trogan.
