Orbital Core

The glass plateau fell into total shadow, save for the weak glow seeping from the hallway. I stood over the battlestation's foundation. A single circular grey component remained unaligned. With deliberate pressure from my gauntlet, I forced the interlocking pegs into place. A satisfying snap echoed through the silent room. The superstructure now possesses a central trench and a functional primary reactor core. It lacks sufficient perimeter defenses, but its structural integrity is absolute. Night has fallen over this domestic sector, yet my fortress expands precisely according to plan.
