The Trinalis Worlds are a group of three habitable planets orbiting separate stars in the Middle Regions. Located more than 700 light years from Earth, they sit far beyond the comfortable travel patterns of the Inner Sphere and depend primarily on Long-Distance Jump access from Outer Station Gamma.
The worlds are known collectively because of their shared route architecture and regional isolation. Their settlement histories, environmental conditions, and economies may differ, but from the perspective of the Inner Sphere they form a recognizable cluster of distant habitable systems.
Because of their distance, the Trinalis Worlds remain imperfectly documented. Reports often arrive late, travel is costly, and outside observers usually encounter the region through station records, trade summaries, or expedition logs rather than direct survey.
