Celestial Mega Structures

Celestial Mega Structures are gigantic accomplishments made by advance civilizations that are just used to show-off their technological capabilities, as a way to create something out of emptiness, or to compensate for something. Either way, these are great achievements with many different functions in the large universe.

 	Dyson Ring World	The Dyson ring world is a large ring that encompasses a star for energy and primarily in the habitable zone. People can build entire environments on the surface of the ring that is facing the sun that produces 24/7 sunlight for ecosystems. Or you could install some giant shaders to simulate nighttime so people can get some sleep. Other times people can turn it into a giant, ring-shaped city station that will act as a center for commerce, academics, government, or one big factory. Yet there are also those that make a large encasement on the surface depending on the type of star.
 	Dyson Sphere 	A gigantic sphere that encompasses the star that feeds on it for energy while also having a 24/7 ecosystem hidden among all the layers of machinery. This jumbo ball of man-made metal is similar to a Dyson ring world but it can actually hide the stars light to keep out any malevolent intruders unless someone has some lights shining on the outside. But structures like these can provide more military purposes with its layers of defensive systems before reaching for the core. However, when encompassing a star with extremely high UV outputs and strong solar winds, it can be one giant power planet.
 	Traveler 	This city size sphere is actually a repository of knowledge and wisdom of an ancient, interstellar civilization that went extinct a long time ago. These spheres have a highly advance AI and are capable of traveling through space on its own. Yet there are some that say that this orb is capable of granting meta-human powers.
(Note: The Traveler is from the Destiny games.)
Own Orbit Image	Moon Orbit Image	Description
 	 	These are smaller ring worlds that orbit around the star or orbit around another planet, like a gas giant. Since these ring worlds are smaller, they have less functionality to it. It could be a nature preserve, a refugee colony, a military installation, or whatever. Or, use it as a super weapon.
