Ringworld

Ringworlds are massive structures, often built around planets, which are quite literally artificial rings. They can also be built in space in place of a planet, as simply a floating ring.

Capabilities
Ringworlds, at their most basic function, provide extra housing when a planet has reached its maximum carrying capacity. They can also function for defense purposes, carrying Turbolasers and Point-Defense systems, starfighter hangars, planetary shield generators, and even an Ultra Laser. They can also be used as massive factories, thus keeping planetside surfaces free of pollution or other environmental problems that comes with excessive manufacturing. Ringworlds around planets can also come with the generators and control consoles for Weather Control Systems. Ringwolds generate artificial gravity, and the civilian models have atmospheres that can allow for plant life to flourish on their surfaces. Alternatively, ringworlds can be fully enclosed and tube-like, with all housing held within them.

Background
Ringworlds were mainly a product of the Old Titanian Empire, created to solve housing issues on less developed planets. They became a staple of luxury for many worlds in the eons after that, and it is not uncommon to see the rich and powerful living on luxurious ringworlds while the poverty-striken majority of a planet live on the surface of the planet itself. Some were used to house factories and manufacturing industries, keeping the world in question free of pollution and destruction. Ringworlds were commonly used for defense in No Man's Space, although they were considered less effective than other forms of protection, as although they generated planetary shields, the ringworld itself was still vulnerable.
