Yamashiro Prefecture, ruled by the Kurosawa Clan, is Umbra’s largest and most technologically advanced territory, thriving on rare resources gained through the Draconis-Yamashiro Treaty. Its foreign-influenced culture emphasizes STEM education and unites its people under a single volunteer army rather than traditional samurai clans.

Formerly abandoned town within an uninhabited outskirt of several Umbra cities, surrounded by barren lands and parts shipyards from which the now-residents use. It is home to a close-knit community of vagrants from any-and-all backgrounds. What started as a small settlement of elderly and/or disabled 'mons looking to make a living, became a safe haven to outcasted individuals wanting to keep a low profile. It is cherished for being away from the bureaucracies of publicly-known and policed areas.

Beneath the scorched, storm-wracked surface of Taenarius lies a thriving subterranean world once built by convicts and adventurers. Though officially ruled by the Yamamoto family, real power remains scattered among the self-governing cities and villages below.

Aerugo, known as “The Junkyard,” is a frigid, lawless moon where scavenger guilds, robots, and ex-prisoners have built a harsh but self-sustaining society from centuries of discarded waste. Trading salvaged parts for survival, its people thrive amid pollution, cold winds, and the ever-present ruins of Ferrum’s excess.

Uzllio is a rain-soaked, oceanic world where Ástro-Hellenes thrive in a direct democracy built atop powerful currents and constant storms. With no natural land and a fiercely protected aquatic ecosystem, its people rely on water power, trade with Silva, and a culture shaped by survival in endless seas.
