Kiirium
this very common metal was used in the manufacture of artificial shielding. Kiirium was transported in large ingots for smelting. Xim the Despot, realizing the need to obtain huge amounts of kiirium to protect his forces, had planned to stockpile kiirium in his vaults on Dellalt. Thus, the Queen of Ranroon was loaded with kiirium when it was dispatched to Dellalt. When Han Solo discovered the starship's cargo, several years before the Battle of Yavin, he discovered that the rumored treasure of Xim was really just a vast supply of military supplies and raw materials.
