New home world of the surviving Talthuns, who escaped the destruction of their world of Talthus when a dark star caused a massive solar flare. The Stromos was bound for this world, along with two other vessels, but was crash-landed on P2A-347 instead. It is not known if her two sister ships reached Ardena. It is also not known if a Stargate exists on Ardena, though it is possible.
Based on the speed of the Stromos, the journey between Talthus and Ardena would take hundreds of years.
