On [[2558#November|November 25, 2558]], a [[Covenant remnants|ex-Covenant]] mercenary organization known as the [[Banished]] launched an '''attack''' on the [[UNSC]] research outposts established on [[Forerunner]] [[Installation 00]].{{Ref/Reuse|The Graveyard}} The assault followed the unexpected shutdown of the installation's [[Portal at Voi|portal to Earth]] during [[Cortana]]'s [[Subjugation of Earth|takeover]] of [[Earth]].<ref name="Guardians">'''[[Halo 5: Guardians]]''', campaign level, ''[[Guardians]]''</ref>

==Prelude==

On [[2558#October|October 28, 2558]], the [[smart AI]] Cortana, leader of an [[AI]] conglomerate known as the [[Created]], arrived at Earth with Forerunner [[Guardian]]s. Firing an [[EMP]] blast at the planet, Cortana caused the shutdown of Earth's defenses.{{Ref/Reuse|Guardians}} In the wake of the attack the ancient extra-[[Milky Way|galactic]] Forerunner sanctuary known as Installation 00, or "the Ark", shutdown the Portal at Voi to prevent the Created from being able to access the installation.<ref name="Mythos202">'''[[Halo Mythos]]''', ''page 202''</ref> With the [[slipspace portal]] gone the [[United Nations Space Command]] research teams on the installation's surface found themselves stranded.{{Ref/Reuse|A New Enemy}}

On [[2558#November|November 25, 2558]],{{Ref/Reuse|The Graveyard}} almost one month after the portal's shutdown, the [[Banished]] led by [[Warmaster]] [[Atriox]], arrived at the Ark in their [[flagship]], the [[CAS-class assault carrier|assault carrier]] ''[[Enduring Conviction]]'', leading a fleet comprised of their [[Jiralhanae]], [[human]], [[Sangheili]], [[Unggoy]], [[Mgalekgolo]], and [[Huragok]] forces.{{Ref/Reuse|Hold the Line}} The Banished deployed Jiralhanae forces, [[Gydrozka Workshop Blisterback]] mobile [[missile]] platforms, [[Barukaza Workshop Scarab|Scarab]] assault platforms, [[Type-26 Banshee|Banshee aircraft]], as well as other vehicles, and began raiding the UNSC research outposts on the surface. Though the UNSC inhabitants of the installation offered resistance against the invaders, they proved no match for the alien onslaught as they were mostly researchers and civilians.{{Ref/Reuse|The Graveyard}} One such research outpost, the [[Henry Lamb Research Outpost|Henry Lamb Research Facility]], was attacked by Banished forces led by Atriox's lieutenant, [[War Chief]] [[Decimus]],{{Ref/Reuse|A New Enemy}} before being directly bombarded by the ''Enduring Conviction''<nowiki>'</nowiki>s [[energy projector]]. A group of fifteen of the outpost's personnel, including archaeologist [[Nathaniel Palmer]] and scientist [[Brewer]], managed to barely escape the assault.{{Ref/Reuse|The Graveyard}} By [[2559#January|January 17, 2559]], the group had atrophied to eight.<ref name="Turn of the Screw">'''[[Halo Wars 2]]''', ''[[Phoenix Logs]]'' – "The Turn of the Screw"</ref>

The destruction of the UNSC presence on the Ark allowed the Banished to establish their forces and set up salvage operations{{Ref/Reuse|A New Enemy}} on the installation before the eventual arrival of the long-lost UNSC vessel, the {{UNSCShip|Spirit of Fire}},{{Ref/Reuse|The Signal}} on March 28, 2559.<ref name="Alice log 1">'''[[Halo Wars 2]]''', ''[[Phoenix Logs]]'' – "Alice-130 Report #1"</ref>
