Trope-a-Day: Dyson Sphere
Dyson Sphere: The Empire has two, although neither by that name, the concept *there* having been devised by Cirys Minaxianos. One, a Cirys bubble, is at Esilmúr (Imperial Core); a thin layer of light-sail material surrounds the star, held up by photon and solar wind pressure in much the same manner as a statite, and managed by magnetic manipulation and selective releases of solar wind. The material, in turn, is coated with energy-producing solar foil, powering massive arrays of antimatter production facilities.
The other, a three-layered incomplete Cirys swarm is at Corícal Ailék, where the Transcend keeps its brain: the innermost being golden-winged energy-collection complexes skimming the corona of the star and powering the rest of the swarm, the middle layer being fractal chandeliers of organic crystal nanocircuitry, providing the Transcend with its massive processing power, and the outermost being the hexterranes, a lattice of hexagonal habitat-plates providing living space here at the heart of the light.
