The Periphery was home to a number of sentient species, including the Defel, the aquatic Sedrians, the Ry'coz, the Vaathkree and the Weequay. Many other species immigrated to the region, including a number of long abandoned Hutt colonies.
Located between Hutt space and the Tion Cluster at the time of the Hutt–Xim conflict, the Periphery was eventually absorbed in Hutt space after the victory of the Hutt Empire.[4] The northern territories of Hutt space, that contained the Periphery, were known as the Kreetan Narrows.[2]
At the end of the Clone Wars, Hutt Space was substantially reduced but the Kreetan Narrows remained under Hutt control. In the months following the Declaration of a New Order, the surrounding regions were the site of important Separatistactivity. After their defeat, the Separatists retreated to the Kreetan Narrows, leadind to the annexation of the region, including the Periphery, by the Galactic Empire.[2] The Periphery became a subsector of the Tharin sector.[4]
Given the region's proximity to Hutt Space, it was often thought that the Hutt criminal empires had significant influence in the region. In actuality, Black Sun controlled much of the region, through its VigoSprax. In addition to this activity, the region had been plagued for many years by the Disac pirates and well as the Ghilron pirates. The Disac pirates caused such significant interruption to Black Sun activities in the region that Ket Maliss, personal assassin of Black Sun's head, was dispatched to eliminate the pirate group. The Dashade was successful in this task, eliminating virtually the entire organization.[1]
