Dyson Spheres
A Dyson Sphere is a shell of material constructed around a star that is able to capture 100% of the stars energy. Uses for this energy include computation in Matrioska brains, moving stars as in Shkadov thrusters, and/or as a weapon with Nicoll-Dyson beams. A Dyson sphere can be built around a star of any size. Dyson spheres form a major component of the planet's Void Mantle and orbital infrastructure but may be embedded in a few million layers of the crust.
