The Slice was a wedge-shaped section of the galaxy which began at the edge of the Core Worlds and extended through the Colonies, the Inner Rim, the Expansion Region, the Mid Rim, and even the Outer Rim Territories. The tip of the Slice was known as the Arrowhead, where modern civilization had been founded. It was roughly bounded on either side by the Perlemian Trade Route and the Corellian Run. After these two major trade routes were established, the systems of the Slice were rapidly developed as colonists followed the two routes and migrated into the Slice in search of habitable worlds.
