Deep within Sol lies the Terran homeworld and cradle of humanity, Earth, from where humankind first ventured out into space. Terran civilisation created the original Terraformer fleets, which later evolved to become the Xenon, and built their own Jump Gates before stumbling upon the existing Jump Gate network; deeds unparalleled within the Community of Planets.
The safety of Sol was always the prime Terran mandate. Under the United Space Command Earth was guarded by the Torus Aeternal, an imposing orbital ring station. Now, as only wreckage of the Torus Aeternal remains, the Terran Protectorate safeguards Earth and its surrounding space with decentralised patrols and access restrictions. Even regular Sol citizens can be denied passage, if they lack the Protectorate Inner Core Access Licence.
