A relatively advanced race, the Taranisians learned to use the Ancient technology at the Ancient base on the planet. When they realised that there was increased Wraith activity, they ordered the shield to run continuously at full power. However, this decision in affect cost the Taranisians their planet, whose previously inactive super-volcano became active. They requested the help of the Atlantis expedition, and trusted them at first to show them an ancient warship. However, soon after when they were told they would have to relocate, the Taranisians became suspicious, but after the Atlantis teams constant attempt to save them, the Taranisians were regretful at their previous behaviour and allowed them to use the ancient warship.
