The '''Zeta Doradus system''' is a planetary system near [[United Nations Space Command|UNSC]]-controlled space. It contains many planets orbiting the star Zeta Doradus, almost all of which are uninhabitable, being icy [[Wikipedia:Terrestrial planet|rocky planets]] or [[Wikipedia:Gas giant|gas giants]]. The one exception, however, is the [[Astroengineering#Artificial planets|artificial planet]] known as [[Onyx]];<ref name="GoO">'''Halo: Ghosts of Onyx''', ''page 150''</ref> or, after its destruction, the [[Trevelyan|shield world]] the planet used to shelter.{{Ref/Reuse|LL}} The system is relatively unknown to the UNSC at large.<ref>'''[[Halo Encyclopedia: The Definitive Guide to the Halo Universe]]''', ''page 301''</ref>

==History==
The Zeta Doradus system was first explored in sometime around [[2491|May 2491]]. The [[UNSC Engineering Corps]] discovered that all planets in the system were uninhabitable, except for [[Onyx]]. When massive subterranean [[Forerunner]] constructions were found on Onyx, the [[Office of Naval Intelligence]] took control of the planet.<ref>'''Halo: Ghosts of Onyx''', ''page 124''</ref> Onyx was removed from the [[UNSC]] navigational databases and the system was considered not a part of [[human]] space.<ref>'''Halo: Ghosts of Onyx''', ''page 149''</ref> ONI began to attempt to uncover the Forerunner artifacts on Onyx. The planet was also used as a training grounds for the [[SPARTAN-III program|Spartan-IIIs]].<ref>'''Halo: Ghosts of Onyx''', ''page 67''</ref> The {{Class|Halcyon|light cruiser}} {{UNSCShip|Pillar of Autumn}} was refit to serve in a conflict near Zeta Doradus in [[2550]].<ref>'''[[Halo: The Fall of Reach]]''', ''page 271''</ref>

In [[2552]], the three-sided [[Onyx Conflict]] was fought in the system between the [[Joyous Exultation Covenant|Covenant]], UNSC, and the [[Onyx Sentinel]]s.{{Ref/Reuse|GoO}} All sides took massive casualties. Towards the conclusion of the battle, Onyx itself disintegrated, only leaving the [[shield world]] in its core intact.<ref>'''Halo: Ghosts of Onyx''', ''page 378''</ref> The shield world was located inside a [[slipspace bubble]] within Onyx. With the help of several [[Huragok]], the shield world was brought back into normal space inside the system and renamed [[Trevelyan]] in [[2553]].<ref>'''[[Halo: Glasslands]]''', ''page 372''</ref><ref>'''Halo: Glasslands''', ''page 367''</ref> When Trevelyan was brought into normal space, it enveloped the three inner planets of the system. By early [[2554]], the shield world had become a [[Onyx United Research Project|joint research project]] between the UNSC and the [[Swords of Sanghelios]] and a colony unto itself, housing a growing population of [[human]]s, [[Sangheili]],<ref name="LL">'''[[Halo: Fractures]]''', "[[Lessons Learned]]", ''page ??''</ref> and [[Unggoy]].

In [[2558]], the [[Servants of the Abiding Truth]] landed on the shield world during the outset of the [[Created conflict]]. As a measure of protection, [[Sarcophagus]] was returned to its [[slipspace bubble]], taking with it the three planets enveloped in its orbit. This marked the beginning of the [[Second Onyx conflict]].<ref>'''[[Halo: Legacy of Onyx]]</ref>
