UX-3 II is the third and outermost planet in the UX-3 System. The air is breathable but this planet is a land of “ice and fire” due to its cold climate, high volcanism, and high oxygen.
In YE 34 the planet was used as a dead drop for items, but the items were not picked up until the YSS Eucharis found them by chance around Halloween YE 35. The items were carried by Star Army Logistics to Fort Hanako.
In YE 34 the Scientific Studies Service (SSS) deployed a Ke-P6-02a Bisen Lighthouse in orbit above this planet at the request of the Star Army of Yamatai. It was placed in orbit due to the level of volcanism.
High oxygen levels mean increased fire hazards and abundant sulfur dioxide gives the air a pungent stench and can severely irritate the eyes, lungs, and skin. Oxygen Toxicity is a concern for many species.
