Merr Sonn is a cold and barren world whose predominant ecosystem is a lifeless tundra. The atmosphere is thin over most of the world and unlivable upon the heights of its mountains. Once a colony world of Sienar, Merr Sonn has only two virtues: a ring of valuable minerals that encircles it, and a competitive alternative to the BlasTech line of weapons. The world is supported entirely through its industry, first mining materials from the rings of their world and then refining them and building weapons.
