Galactic Atlas

Sinisi Prime is characterized by its long, widely-spaced stellar corridor, where neighboring systems are often separated by greater distances than elsewhere in the galaxy. While nebulae are uncommon, the wing is supported by unusually long and stable slipstream branch channels that converge through a small number of junctions. Because of this, travel throughout the wing naturally funnels through relatively few crossroads, making the control of gateway systems and slipstream junctions especially important. Throughout history, influence within the wing has been measured less by the size of one's territory than by command of its major transit routes. As a result, the wing's great powers have repeatedly competed for control of the same strategically important gateway systems, many of which have passed between rival states while retaining strong regional identities.

The Inner Ring is the densely packed stellar region immediately beyond the Umbral Ring surrounding Umbra, the supermassive black hole at the center of the galaxy. It is among the most volatile regions of known space, characterized by young stars, binary star systems, and unstable stellar nurseries. On many Inner Ring worlds, the night sky never becomes entirely dark. Nearby stars cast a perpetual twilight across planetary landscapes from all directions, while elevated background radiation makes planets with thick atmospheres or powerful magnetic fields favorable for habitation. The Inner Ring is also the most heavily traveled and fiercely contested region of the galaxy. Throughout the ages, civilizations have risen and fallen in their struggle to control the slipstream junctions that converge upon the Umbral Ring, making the region the political, economic, and strategic heart of known civilization.
