P3X-513 is a forested planet with dangerously high levels of ultraviolet and infrared radiation. During the mission of SG-9 to the planet, Captain Hanson had proclaimed himself a god among the natives, primitive inhabitants who lived as nocturnal cave dwellers. SG-1 overthrew Hanson and restored the Goa'uld ultraviolet energy shield that turned the sky orange and offered protection from dangerous radiation, enabling the inhabitants to live outside the caves.
