The Milky Way is a barred spiral galaxy with two major arms and a number of minor arms or spurs. The Perseus Arm begins from the distal end of the long Milky Way central bar. The Perseus Arm is almost completely unexplored - a few [[Commonality]] expeditions have ventured from their colonies in the [[sector:Empyrean Roots]] into the [[sector:Near Perseus Sector]] in the past century, but have reported little than basic surveying and mapping information.

The Perseus Spiral Arm in the Orion Sphere area lies approximately 35,000 light-years from the galactic core, and is located between the minor [[Orion Arm|Orion]] and [[Saggitarius Arm|Saggitarius]] Arms. The Perseus Arm is separated from the Orion Arm by the [[Perseus Rift|Great Perseus Rift]], a particularly sparse region of space. The few areas of stellar density crossing the Rift tend to form thin threads that weave together connecting the two arms - the Binding Strand of the [[sector:Binding Sector]] and the Empyrean Roots of the [[sector:Auriga Sector]] and [[sector:Perseus Rift#Perseus Rift Epsilon Sector|Perseus Rift ε Sector]]. It is named after the Perseus constellation, which was visible in its direction from pre-Fall Terra.
