Galactic citizens know little about the strange worlds and isolated civilizations beyond the reach of the official galactic government of their time. Even the frontier worlds on the edges of known space know little of the nearby systems of The Unknown Regions. These areas are regarded as isolated and dangerous, and only the desperate, brave, or foolhardy venture into them on a regular basis. However, over the course of galactic history, new political entities and armed invaders emerge from The Unknown Regions to threaten isolated worlds or even the greater galactic government of the time.
