Norfair

Norfair is one of the most inhospitable areas found on planet Zebes. Located deep beneath the planet's surface, Norfair is a highly-active volcanic caverns, and home to many highly adapted creatures. Symbolized by massive lakes of magma, superheated caverns, and boiling streams of highly acidic substances, Norfair is by far one of, if not the most, dangerous places on Zebes. Also, going even deeper into Norfair reveals ancient Chozo constructs left abandoned, save for the Space Pirates who, during the events of Super Metroid, had constructed a massive base there. Within the deeper sections of Norfair, also resided Ridley, the leader of the Pirates' military.
