Shield world

From Halopedia, the Halo wiki

A Shield World is a complete and thorough Micro Dyson Sphere within a Slipspace transit built and constructed by the Forerunners in their vast empire. They contain environments suitable for Earth's sentient life. The only way in is a small portal that constitutes the only real-space component of a Shield World. One of these portals is located inside the Core Room Antechamber within Onyx.

Dr. Catherine Halsey theorized that Shield Worlds were intended by the Forerunners as a form of a modern "bomb shelter," a place in which to ride out the devastating Halo pulse. As demonstrated in 2552, access to Shield Worlds was only possible upon the imminent activation of the Halos.

Curiously, when Halsey and company fled into Onyx's Shield World during the last stages of the Battle of Onyx, it appeared to be deserted, implying that the Forerunners did not utilize it when the Halos were last activated.[1] 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 Forerunners to abandon their plans to evacuate into the shield installations.

Unlike the Halos, it is unknown how many shield installations exist. It is possible that there are only seven of them (keeping with the seven reference). When the Forerunners built the Halos, it's possible they built an accompanying shield world with each. The Halos would destroy all sentient life within a 25000 light year radius of itself while the shield world would protect any sentient life within that region.





Trivia

  • Worlds like Onyx were referred to as "The Shield" of the Forerunner, while the Halos were "the Sword." This echoes Cortana's line on the Halo 3 Announcement Trailer, "I am your shield, I am your sword." So far, Bungie has said nothing about a correlation between Cortana's use of the word "Shield" and the Forerunner's "Shield World."
  • A "shield installation" is mentioned in the cutscene on the level "The Ark" in Halo 3. 343 Guilty Spark states that he had hypothesized that the Ark might be located within such an installation, but was proven wrong by the discovery of its location on the exterior of the galactic rim.
  • The Shield World's glyph can be seen in the cover of Halo: Ghost of Onyx, hinting and supporting that the novel was to focus mainly on the subject.[2] There is quite an uncanny resemblance between this glyph and a glyph seen on the world discovered at the end of Halo 3 when completed on legendary, which may confirm that Master Chief and Cortana are heading towards the/a Shield World, or rather, the Forerunner construct that might lead to the Shield World (like the object on Earth that was originally considered to be the Ark).[3]
  • In Terminal 5 of Halo 3, there is a sentence that reads the following "If we start immediately--commence total biosphere elimination of life sustaining worlds (as indicated in the accompanying charts) and relocate evacuated populations to facilities such as those described in the [Onyx project] all this could be achieved in [57,1590 (+/-2,184) hours]." This is most likely a reference to either the Forerunners Shield World(s) plan or Onyx itself.
