Dyson Sphere

Dyson Spheres, also known as Star Drives, Sun Batteries, and Solar Stations, are megastructures that can create enough power to fuel star fleets and solar systems.

Capabilities
Dyson Spheres are built around stars, extracting energy directly from them, and can store and redistribute said energy. Solid Dyson Spheres are built with Novanium interiors, which can also carry over to satellite grids. Solid Dyson spheres also act as artificial suns, as their coverings would otherwise blot out the life-granting stars that they are built over.

History
Dyson Spheres are among the most advanced technological feats of most species. Exa, the homeworld of the Exans, was converted into a Dyson Sphere at the last stage of its development, upgraded far beyond a Planetoid Warship, and the first Dyson Sphere to hold an artificial star.
