The Taranis outpost was an outpost built by the Lanteans during the war with the Wraith. The outpost also served as a drydock for ships of the Lantean fleet, and one of them, the warship Hippoforalcus, remained behind when the Lanteans fled to Earth. The dialing device was similar to the one in Atlantis, and was actually located in the outpost itself some distance away from the Stargate. The outpost was located in the center of a supervolcano, and boasted a shield that was powered by geothermal energy. Unfortunately, the Taranians kept the shield constantly active at full strength after they learned the Wraith had left their hibernation cycle prematurely. This caused the heat and pressure inside the supervolcano to build to the point that it became active again and was about to erupt when the Atlantis expedition discovered the outpost one year later. The resulting explosion destroyed the outpost, most the continent the outpost was on, and rendered the planet uninhabitable for centuries. (ATL: "Inferno")
