Yulin III

Yulin III is the third planet from the sun of the Yulin system, Banu Protectorate. Located on the outer edge of the habitable zone, it is cold but temperate enough to be habitable for Banu. However, its ammonia oceans and high-pressure, methane-rich atmosphere make it inhospitable to those of other civilizations. To Banu, Yulin III is a relaxing resort world. Enterprising Soulis have created a sealed arcology to encourage non-Banu vacationers to experience the planet's strange beauty.
