Helios Prime is both a world and a statement. Once Earth's proudest off-world colony, it has grown into a sprawling globe-spanning arcology: continent-sized cityscapes threaded with transit rings and orbital elevators.

From Helios orbit, the Accord governs. The Helios Crown Array, a lattice of fortified stations and comm-relays, acts as the central hub for diplomatic traffic and high-level military coordination, storing vast archives of precedent, treaties, and administrative law, updated daily.

Most high-ranking Solarii spend part of their careers on Helios Prime, learning how to think at the scale of sectors rather than stations.
