Ukmirt is a star system Southwest of Fujiko and Southeast of Nellrun. It was held by the Mishhuvurthyar back in the First Mishhuvurthyar War.

Although many the citizens would like to be part of the Yamatai Star Empire, the YSE left the system alone as Independent until YE 38 when it was claimed by the YSE during the International Relations Conference of YE 38. The reason was to create a larger buffer against the spreading Rixxikor. They quickly built a Frontier Starport on Ukmirt II.

1. Ukmirt I: A hellish, barely habitable world of ashen deserts and oceans of molten rock.
2. Ukmirt II: An Earth-like planet with a mild climate and reliable seasons. The planet's landmasses are situated in the temperate zones, featuring open and rolling landscapes with little variation in altitude. High winds sweep across the plains and across the cold brackish seas. There are few inland waterways, and the shorelines consist mostly of rocky bluffs, offering little in the way of safe harbor for seagoing vessels. The planet serves as an agricultural colony and is home to roughly 18 million people, primarily Nepleslian Reds. The Star Army of Yamatai has a small military base on this planet, primarily to cement its territorial claims. Trinary Star Shipping has a facility here as well.
