Welcome to the raggedy edge of human space, The Orion Frontier. This is the edge of human exploration. Rimward from here, There be Dragons! No star chart or encyclopedia tells us what lies beyond, only whispered tales of scouts and pirates provide us myth- inspired answers.
But here there is life, life in abundance and wonder to boot. The edge of the Orion Frontier is an arbitrary area of space called The Twilight Sector. Legends on the naming of the place abound. Was it a joke of some bureaucrat disgruntled with his posting, just the poetic license of those who came to call the place home or a comment on it being the last spec of human settled space? Arguments and evidence for each claim abound and it’s unlikely any will ever know the truth of the matter. What The Twilight Sector does have though is a wonder. Earth! Or at least an exact copy, and by exact copy I mean exactly that. The planet is a beautiful blue green ball of cosmic habitat that resembles the mother planet down to the shape of its continents.
A prize of great value and one the Orion’s were, and are eager to hold on to. Thus with the coming of The Mutant War ties with the area were not lost. In fact they were strengthened. A class one world with incredible resources far removed from the front lines of the war was a ruby beyond price and this fact was not lost on either the Orion military or political leadership. Terra/Sol, as the system became known, quickly became one of the major arsenals of the confederation. Although further exploration of the Orion Frontier ground to a halt, the systems in the Twilight Sector on the edge of human settlement never had to want for the notice of their loving parent.
