Councilor Lucia Tarthus is an Andari representative on the Joint Ruling Council of Langara. When the expansion of unstable naquadria threatened to destroy the planet, Councilor Tarthus joined First Minister Dreylock of Kelowna and Councilor Eremal of Tirania at the SGC for negotiations to avert the crisis. The distrust among the three nations made any negotiation nearly impossible, and Tarthus, who failed to comprehend the threat to her own people, offered only humanitarian aid to Kelowna, and insisted upon a separate planet for the evacuation of Andaris.
