Langara

"Langara is the new name of our planet. It's from an ancient dialect common to all three nations."

Langara, or P2S-4C3, is a world in the Milky Way galaxy.

History
Some time ago, it was occupied by a Goa'uld known as Thanos, who brought humans to the planet some three thousand years ago. Thanos attempted to create a new form of naquadah called naquadria, but his experiments nearly destroyed the planet.

It's unknown whether Thanos survived the incident, but it is not likely since the world was afterwards abandoned by the Goa'uld. Over the millennia, the inhabitants of the planet become more technologically advanced and, by the early twenty-first century, it was ruled by three superpowers, Kelowna, Tirania and the Andari Federation.

These three nations were, and arguably still are, highly distrustful of each other. In fact, the Kelownans began creating a bomb using the planet's naquadria, which was found mostly in their territory. Around the Earth year of 1986, the Kelownans discovered their planet's Stargate although they did not know what the device was until SG-1 visited the planet in 2002.

Kelowna helps develop and share technology with Stargate Command. The planet's most famous inhabitant is Jonas Quinn. Unfortunately, due to the failure of the naquadria bomb and framing Doctor Daniel Jackson for its loss, Earth withdrew all communications.

A year later, the Tirania and Andari were close to joining forces, forcing Kelowna to ask Earth for help, but Stargate Command refused to give any 21st century technology that could be misused. With little choice,Kelowna used the naquadria bomb, which they later regretted, for its power devastated all three nations, who went to the negotiating table.

After Anubis attempted to conquer Langara and take the naquadria, Kelowna, Tirania, and the Andari Federation chose to form a joint council, which would cooperate with each other. Langara was nearly devastated when a naquadria vein came close to exploding, but Jonas and SG-1 were able to avert it.

During the Ori invasion of the Milky Way, Langara was conquered shortly after the devastation of Dakara. There has been no contact with the Langarans since, but with the use of the Ark of Truth, the remaining population would have been liberated.

It's possible that due to its Naquadria Core, Langara may be able to dial the Destiny
