The Sector today known as Diaspora was only sparsely settled by the First Imperium Vilani, who called it Nakulakak. When the expanding Terran Confederation exploded into space, Vilani efforts to develop the area were described by on Terran general as "Too little, too late, too slow: too bad." Attempts to use it as a buffer zone only made it easier for the Terrans to conquer portions of it, and ultimately the Vilani began trading bits of it away in attempts to appease the voracious invaders.

Now, the Diaspora Sector is the crossroads of contact and trade between the Imperial Core and the Solomani Rim.
