Imagine the Maginot Line, but built across the entire perimeter of a spiral galaxy. It is impossible to build evenly. Thus, you identify the "choke points"—regions of low dark matter density or natural warp storms—and you fix your fortress there.
Galactic limits adjusted to ensure smoother late-game performance. galactic limit final hold fixed
The "Fixed" nature refers to gravitational anchoring. A star system inside the Limit is gravitationally bound to the galactic core. Outside the Final Hold, the local group’s tidal forces begin stripping systems away. In a mere 100 million years—a blink in galactic time—any colony beyond the Limit would find itself drifting in intergalactic space, severed from all trade and aid. The Hold is fixed because gravity is fixed. Imagine the Maginot Line, but built across the
