UX-1 is a binary star system located near Plumeria's Gap, Vicky, and Sbuhfaba, giving it a strategic location.

This system was once claimed by the Yamatai Star Empire, which had an outpost on the first planet, UX-1 I. Currently it is unclaimed.

In YE 34 the Yamatai Star Empire built a Frontier Starport on the surface of UX-1 I but it was abandoned after the end of the Second Mishhuvurthyar War.

In YE 35 the Scientific Studies Service (SSS) deployed a Ke-P6-01a Bisen Lighthouse on the surface of the of UX-1 I at the request of the Star Army of Yamatai.

The YSS Eucharis visited this system from YE 37 to YE 38.

In YE 38, the lighthouse was destroyed by explosives planted by a Rixxikor hit squad.

In YE 41, during the Kuvexian Invasion of YE 41 (part of the Kuvexian War), UX-1 fell to the forces of the Interstellar Kingdom Of Kuvexia and was under occupation.
