Colonised by the survivors of the First Terraformer War, the Sonra system is seen by many as the birthplace of modern Argon civilization and culture. Renamed from Sonra to R. Gunne to commemorate the hero of the First Terraformer War, then to Argon Prime, the system has served as the capital of the Federation for all of its five hundred and eighty-four years. As such, the fourth planet, also called Argon Prime is steeped in history, and even despite the Jump Gate shutdown, the system once again thrives on a strong trading and tourist economy.
Argon Prime is excellent for its access to the highway ring and ship production facilities but is severely lacking in the resources department. Its pockets of resource are not in sufficient quantities to support much industry, however, this is significantly mitigated by access to Second Contact and The Reach.
