Aeten II is located in the Outer Rim and plagued by volcanic activity, Aeten II is known for its deposits of rare stygium crystals, which are used in the construction of cloaking devices. Because stygium crystals are extremely valuable, a number of unscrupulous prospectors descended upon Aeten II, where they competed for the rare crystals with abandon. As a result, Aeten II became one of the most dangerous planets in the Outer Rim Territories. By the rise of the Empire, Aeten II's cache of crystals had been all but depleted, making the manufacture of new stygium-based cloaking devices a near impossibility. Prospectors looking to retool old mining facilities here have since found other valuable resources to mine.
