The Aquila Rift was the name given to a molecular cloud located in the anti-spinward region of the Deep Periphery. The Aquila Rift was a major astrogeographical feature, and the largest of three identified significant molecular clouds in the anti-spinward Deep Periphery. Encompassing a region wider than the full extent of the Lyran Commonwealth, the Aquila Rift is a dark interstellar cloud made up of molecular dust clouds dense enough to obscure the stars that lie beyond it from astronomical observations; those star systems that lie within the Rift itself have very dim night skies, with typically only a small number of stars shining brightly enough to be visible through the dust of the Rift. The Aquila Rift lies close to the Periphery border of the former Rim Worlds Republic, and between the border of the Rift and the edge of the region that was once the Timbuktu and Erdvynn Provinces of the Republic lies the Lupus Cloud, a large nebula. Stretching from the borders of the Axumite Providence - a notable nation in the Deep Periphery, located close to the anti-spinward border of the Aquila Rift - around the edge of the Aquila Rift and down to the relatively young and open stellar cluster known as Caesar's Crown is a chain of bright star systems known as Caesar's Bow, an astronomical feature with a relatively high density of habitable worlds possessing complex forms of life.
While there were numerous colonies in the anti-spinward region of the Deep Periphery by the height of the Star League, some dating back as far as the twenty-second century, the Amaris Civil War and the fear of being the subject of reprisal attacks aimed at those perceived to be allies of Stefan Amaris led to those colonies with HPGs in the region shutting down communications with the Inner Sphere, with many smaller colonies physically relocated deeper into the Periphery. The mystery of the disappearance of the Star League Defense Force during the Exodus focussed deep space explorations on the Coreward regions of the Deep Periphery, and as a result the anti-spinward region of the Deep Periphery - including the vast expanse of the Aquila Rift - received little attention for centuries until expeditions by Interstellar Expeditions began probing the region in detail.
Aquila Rift was first identified in 2012 with the publication of Interstellar Players 3: Interstellar Expeditions. Other than the location of Aquila Rift and its definition as a nebula, no information was provided on the feature; in the absence of further information on the Deep Periphery no further detail is likely to be available on Aquila Rift.
