Regions

''The navigation hologram erupted into light in front of her, illuminating the dim interior of the small Megacorp freighter. At her touch, the three nebulae spun through the air, where her fingers stopped, names of suns and systems she had never seen, and likely would never know, glimmered before her. She sighed as she zoomed out, limiting the display to the vast regions of the known galaxy. Boxes of various neon shades emerged and bordered incomprehensibly large areas of space. She always wondered why they were boxes. A blinking light deep in the Malpais region provided her with all the disappointment she needed. It would be another month before they reached the Stargate, probably another month after that before they reached Enosis. Two months until she saw her beloved, and the Megacorp hadn't even provided her with enough Hypersleep drugs to wait out half that time. She sighed and closed the hologram. Darkness crept back into her cabin as she lay down on the stiff mattress. In the bowels of the mammoth ship, she closed her eyes and dreamt of home.''

Regions in Rasalum
Since the dawn of time, species across the galaxy have placed themselves inside the greater whole, separating what is familiar to what is unknown, what is friendly to what is dangerous. Spaceflight did nothing to curb these instincts, and by 1000 AP almost all of Known Space has been divided up into informal, though universally understood, Regions.

These Regions are rarely anything more than lines on a map, created for a myriad of reasons. Some are simply to mark an area within an unusual stellar phenomenon, others denote the home territory of vast empires. The division of the known galaxy into Regions is therefore a matter of convenience rather than doctrine, and each region, from the Glacarin Basin to Malpais each has its own history, crises and culture.

A Note on Worldbuilding
Regions serve as a means to not only link ideas through proximity, but also thematically. Ideally, each region should have an overarching theme or feel, and each addition to that region should reinforce (or deviate, if its more interesting) from that theme. This isn't to say that thematically dissonant species, concepts or ideas can't co-exist in the same region, its more a rule of thumb to try and make the vast reaches of space interesting and recognisable from a storytelling perspective.
