Tarvis, designated P3X-540, by the Tau'ri was a planet in the Milky Way galaxy that was ruled over by the Goa'uld System Lord Bastet. Tarvis is covered with thick jungles of the Amazon resembled the Earth. Occasional rain forests dot the area around the equator, but most of the time the planet is completely wild and untamed. Various hazardous forms of wildlife has evolved in Tarvis, including one of the galaxy's only known carnivorous species of trees. In addition, a wide variety of poisonous insects and snakes lurking under every bush while other large animals stalk their prey for days at a time before pouncing.
Tarvis is one of the most lethal naturally occurring environments in the galaxy thanks to its unique collection of flora and fauna. There are also strains Sekhmet, which has carved out a home in the world by taming a small part of their wilderness. (RPG: "Living Gods: Stargate System Lords")
Bastet frequently takes prisonners, from rebel Jaffa to other System Lords and turns them loose in the jungles of Tarvis. Then the hunt begins. Bastet uses this planet as a vicious playground to satisfy her baser urges, often hunting her enemies alone with a small group of her faithful Jaffa. Usually, if she doesn't take care of her enemies, the planet does it for her. (RPG: "Living Gods: Stargate System Lords")
