Unknown Regions, The
originally considered areas of Imperial occupation beyond the universe defined by the Old Republic, the Unknown Regions contain the vast majority of the known, though unexplored, galaxy. By the time of the Yuuzhan Vong invasion of the galaxy, the Unknown Regions accounted for just fifteen percent of the galaxy, yet much of it remained unexplored by the New Republic. The primary reason for this was the fact that the Chiss controlled most of the border between the Unknown Regions and the rest of the galaxy. They severely limited traffic into the Unknown Regions, but they also mapped large portions of the Unknown Regions as part of an ambitious mission developed by Grand Admiral Thrawn. Decades of exploration revealed a wealth of unusual creatures and races, along with a wealth of information on the appearance of therogue planet Zonama Sekot.
