Infernus

Infernus planets - redder, magma-y-er, and burnier. They are hot and deadly. The atmosphere itself tries to kill you, it rains lava and fire AND there are strange creatures wandering around just waiting to murder you. Without good protection (and some sort of hazard suit or immunizing plant) you won't last long on such world. They are an excellent source of many minerals, Cinnabar being chief among them.

Infernus worlds (and their variant Dark Infernus) are the sole source of Pyreite Ore.
