The Langarans are a human race native to Langara. They are divided into three superpowers: Kelowna, Tirania, and the Andari Federation. Langaran civilization have technology roughly equivalent to that of Earth near the end of World War II, industrial but still missing technologies like jet propulsion and antibiotics.
The three superpowers had undergone a long period of mistrust, but a military alliance between Tirania and the Andari Federaton caused Kelowna to design a naquadria bomb. The detonation of the naquadria bomb actually de-escalated tensions in the long term by getting the three powers to come to the negotiating table, eventually agreeing to the creation of a world ruling body.
