Perseus Arm

The Perseus Arm is the next major spiral arm of Galaxias found rimward of Charted Space.

• It lies between the Sagittarius Arm and Orion Spur to coreward and the Outer Arm to rimward.
• It is part of Galaxias or the "The Milky Way."

Description (Specifications)

LOCAL GALACTIC STRUCTURE:

Map combining both concepts: The "Rimward Spur" of the more coreward arm joins further to spinward with the Perseus Arm, of which it is a coreward branch.

The Local Region of Charted Space lies within a galactic arm of stars to coreward (known as the Orion Spur or Orion Arm) of the Perseus Arm. Scientists currently debate as to whether or not the Local Region of Charted Space actually lies within a rimward Spur of the Sagittarius-Carina Arm known as the Orion Spur, or whether the Local Arm is actually a more substantive minor arm of its own (the Orion Arm) that is a coreward split from the Perseus Arm. The Perseus Arm itself may have its origin as the winding extension of the Far 3kpc Arm, and on the near side of Galaxias lies just coreward of the outermost extended arm of Galaxias as a whole, the Outer Arm.

The inner edge of the Perseus Arm along a 125° (± 15°) spin-rimward bearing from Charted Space and spanning over 2000 pc lengthwise along the arm is a region of star-formation known as the Cassiopeia Region, and contains the Cassiopeia OB2, OB5, OB6, OB7, and OB8 Associations, as well as the Perseus OB1 Association between Cassiopeia OB6 and OB8.

History & Background (Dossier)

The Perseus Arm has been intermittently contacted by explorers from Charted Space over the millennia. Turokan's Expedition to the Galactic Rim purportedly crossed the Perseus Arm along a rimtrailing bearing from Charted Space in Galactic Quadrant III as he pushed on toward the Galactic Rim, and it is uncertain just how far advance scouts and private ventures of the Solomani Rim Expeditions have pushed along the Rimward Corridor between Galactic Quadrant II and Galactic Quadrant III . Aslan ihatei and Hiver curiosity likewise are driving forces for those respective rimward polities, but their individual efforts in rimward exploration or expansion remain unknown.

The far-flung and isolated pocket of civilization known as the Matzen Sector Region lies approximately 3000pc rimspinward of Charted Space within the Perseus Arm in Galactic Quadrant II.
