A '''Dyson Sphere/Shield World''' (or "shell" as it appeared in the original paper by Freeman Dyson) is a hypothetical megastructure that was originally described as a system of orbiting solar power satellites meant to completely encompass a star and capture its entire energy output. Dyson speculated that such structures would be the logical consequence of the long-term survival of technological civilizations, and proposed that searching for evidence of the existence of such structures might lead to the detection of advanced intelligent extraterrestrial life.

A three meter thick Dyson Sphere with an [[Earth]] orbit radius would require an estimated 2.12057325 x 10<sup>23</sup> cubic meters of material.

In the book [[Halo: Ghosts of Onyx]], it is disclosed and revealed that at the core of [[Onyx]], there is a [[Slipspace]] rift that shunts those that pass through it to a structured ''Dyson Sphere'', dubbed beforehand by the Forerunners as a [[Shield World]] [[Installation]]. It is separated from a normal space-time symmetry by advanced Forerunner Slipspace technology. Although [[Dr. Halsey]] calls it the '''Micro Dyson Sphere''', the Sphere is 300 million kilometers (or approximately two astronomical units(1 AU is 149,598,000 km)) in diameter on the inside. The Micro Dyson Sphere's star has a spectra and energy output slightly smaller than the dimensions of [[Sol]]. This was going to be the haven where the [[Forerunners]] were to seek refuge when [[Halo]] activated, but no one knows what went wrong with their alleged plan, as the expanse appeared to be completely deserted when [[UNSC]] forces arrived. In [[Halo 3]], these circumstances were revealed to be the result of the betrayal of the [[Forerunner]] [[AI]] [[Mendicant Bias]], whose defection to the [[Flood]] forced the [[Forerunner]]s to abandon their plans to evacuate into the shield installations.

Basically, the structure fulfills its function as a "Shield World" perfectly. It protects the occupants of it and gives them a huge "world" to live in. Potentially, an entire new civilization could be constructed in a Dyson Sphere.

After their arrival in the Forerunner-constructed Dyson Sphere, [[Dr. Halsey]] explains the structure. She calls and entitles it a Micro Dyson Sphere because it is in fact very small, or perceived to be small when viewed from normal space.

The Micro Dyson sphere is located in a ''factually'' compressed Slipstream space. In other terms, any object inside might appear to be a certain size, but inside the Slipstream bubble it is much, much larger. Consequently, they never left [[Onyx]], but simply entered a Slipspace bubble.<ref>{{Quote|"Entirely true," Dr. Halsey said, "but we have not left Onyx."<br>"This is the part I don't get," [[Kelly]] muttered.<br>"The [[Forerunners]]' grasp of Slipspace technology was far more advanced than ours or the Covenant's," [[Dr. Halsey]] explained.

In [[Halo Wars]], there's also a type of Micro Dyson Sphere. However, this [[Shield World]], as referred to in the game, is vastly different from the [[Onyx]] installation.
In ''[[Halo Wars]]'', there is also a type of Micro Dyson Sphere. However, this Shield World, as referred to in the game, is vastly different from the Onyx installation.
Unlike Onyx, which was made up of trillions of [[Onyx Sentinel|Sentinels]], over which a planetary surface had formed, this world was built in a method similar to a [[Halo Installation]]. It was a hollow structure with planetary surfaces on the interior and exterior being supported by numerous pillars. Inside this was a more familiar construct of ship-sized portals allowing access from an opening on the outside to the interior world. The interior was somewhat similar to Onyx's Dyson Sphere, possessing an artificial sun, though it and the entire structure are on a far smaller scale. However, unlike Onyx, it was not designed as a bomb shelter, but as some sort of harbor, shipyard or hiding place for ships, as it contains [[The Apex]], which had dozens of [[Unnamed Forerunner Starship|Forerunner ships]] stored within it. It is unknown whether the same is true for the Onyx Installation, but if it is, then it may have served as a possible means of escape for the [[Spartans]] trapped there.
