[[Requiem]] was the first shield world to be constructed, its design later serving as the template for the entire concept.{{Ref/Reuse|sil278}} This variant features an entirely artificial, heavily armored outer surface and contains several concentric miniature Dyson shells within its outer shell. Like the exterior, the interior surface of the outer shell is mechanized and features a light source for warmth and illumination. Another sphere, containing a terrestrial surface-oriented similar to a planet, is located below the outer shell. The interior of this shell contains the hollow core of the shield world and a Dyson shell-like inverted surface.

===Micro Dyson sphere===
===Micro Dyson sphere===
The main component of this type of shield world is a [[Dyson sphere]] located within a bubble of compressed [[Slipstream space]]. The only entrance to the interior is a small portal within the core of an artificial planet built around the core. Access to these shield worlds is possible only upon the imminent activation of the Halo Array.{{Ref/Novel|Id=goo311|GoO|Page=311}}

The Dyson sphere within this type of shield world is enormous; [[Sarcophagus]], for example, is two astronomical units (300 million kilometers) in diameter. As with the more common conservation spheres, micro Dyson sphere-type shield worlds feature vast terraformed surfaces and a single artificial star. The inner Dyson sphere resides within a slipspace bubble and is thus accessible only from the [[core room antechamber]] in the heart of the artificial planet formed around the structure. In normal space, the slipspace bubble is radically smaller than the interior, being only a few meters in diameter, hence the moniker "micro Dyson sphere".
