Caldera - Lava Planet

Welcome to Caldera, a once mundane planet that was driven to its current state by a recent (in cosmic terms) impact that devastated its surface and atmosphere, and gave it an impressive set of rings. Wide rivers and seas of lava are spread throughout, cutting between plains of ash-covered rock and jagged mountains; leaving fresh beaches of cooled lava rock. Enveloped by thick clouds of ash and sulfur, Caldera's temperature remains extremely hot over its entire surface with devastating ashstorms that occasionally sweep by its basins. Despite being a true hellscape, the impact had deposited a plethora of heavy elements under its surface free to be exploited by those who can survive Caldera's hostile conditions, just don't expect to find any ice.

Believed to be a comet that was captured shortly after Caldera suffered its impact, the eloquently named KL-136 is rich in what Caldera isn't: Ice. Its rough surface is covered in it, but only common ores can be found under its surface.
