'''Eridanus II''' is a [[human]] [[Outer Colony]] [[planet]] in the [[Eridanus system]]. The planet was mostly rural, devoid of pollution or crowding, and had climate-controlled weather.{{Ref/Novel|[[Halo: The Fall of Reach]]|Page=22}} It was famous for its beautiful landscapes and higher learning centers.{{Ref/Reuse|JALP}} It was the location of the [[city|cities]] of [[Luxor]] and [[Elysium City]], where [[John-117]] grew up until he was abducted and sent into the [[SPARTAN-II program]] in [[2517]]. [[Emile-A239]] was from Luxor, born there in 2523.{{Ref/Site|URL=http://halo.bungie.net/projects/reach/article.aspx?ucc=personnel&cid=24523|SiteName=Bungie.net|PageName=Emile's profile page|Detail=(Quote)}}

==History==
===Rise of humanity===
Eridanus II was settled in [[2440]].{{Ref/Reuse|Enc22}}{{Ref/Reuse|encpg47}}
====Insurrection====
The [[Eridanus secessionists|secessionist rebels]] in the system staged a localized rebellion against the UNSC in [[2494]] and briefly took control of the planet.{{Ref/Book|Id=mythos|Halo Mythos|Page=55}}{{Ref/Site|Id=universe|URL=https://www.halowaypoint.com/en-us/universe/characters/colonel-watts|Site=Halo Waypoint|Page=Colonel Watts|D=13|M=4|Y=2016}} The UNSC struck back two years later in [[Operation: CHARLEMAGNE]] and forced the rebels out at the cost of four [[UNSC destroyer|destroyers]].{{Ref/Reuse|enc44}} A large number of rebels survived, however, and under the command of the UNSC turncoat [[Colonel]] [[Robert Watts]], overthrew the civilian government of the system in [[2513]]. Watts was presumed killed in the UNSC's counterattack, [[Operation: TREBUCHET]], but in fact he escaped to [[Eridanus Secundus]] in the system's [[asteroid]] belt with the rest of the rebels.

In [[2517]], Dr. [[Catherine Halsey]] and [[Jacob Keyes|Lieutenant Jacob Keyes]] visited the planet during the former's mission to observe the [[SPARTAN-II program|SPARTAN-II]] candidates. Halsey met [[John-117]] at a playground in [[Elysium City]]'s [[Elysium City Primary Education Facility Number 119|Education Facility 119]], where she determined his admission into the program with the flip of [[quarter|an antique coin]].{{Ref/Novel|Id=FoRpg21-25|Halo: The Fall of Reach|Page=21-25 (2001)}}

As part of Operation: TREBUCHET in [[2524]], [[Colonial Military Authority]] Marines attempted to raid an [[Insurrectionist]] base on [[Teribus Island]]. Sympathizers in the unit tipped the Insurrectionists off, and by the time the dropship arrived it had been abandoned. Later, a nightclub in Elysium City was targeted by Insurrectionist bombers because it was a favorite CMA area for off-duty personnel, killing dozens of civilians and a CMA pilot, [[Allison Stark]] and putting a CMA Marine, [[Eric Santiago]], into a coma. [[Gage Yevgenny]] and [[Felicia Sanderson]] were injured, but survived the attack.{{Ref/Anthology|Evo|[[Dirt]]}} Around this time, [[refugee]]s from Eridanus II ended up in [[Pirth City]] on [[Arcadia]] and [[New Jerusalem]].{{Ref/Generic|[[Hunt the Truth]]}}

It remained a place of much hostility against the [[United Nations Space Command|UNSC]], and many [[piracy|pirates]] and rebels continued to operate across the system, with the asteroid belt as their main base of operations. John-117 returned to the system in [[2525]] with the other Spartan-IIs aboard the [[UNSC destroyer|destroyer]] {{UNSCShip|Pioneer}} for their [[Assault on Eridanus Secundus|first mission]] to capture the rebel leader, [[Robert Watts|Colonel Robert Watts]]. The Spartan team boarded the cargo freighter ''[[Laden]]'' and traveled to the rebel asteroid base Eridanus Secundus, where they successfully captured the Colonel and escaped.

At an unknown time, a skirmish between UNSC and Insurrectionist forces during [[Operation: ROCK HOUSE]] took place.{{Ref/Game|Halo 5: Guardians Limited Edition|[[Halo 5: Guardians Limited Edition dossiers#Frederic-104|Dossier files]] - Frederic-104}}

===Human-Covenant War===
{{Main|Human-Covenant War}}
At some point during the Human-Covenant War, [[Operation]]: [[Operation: BLUE MOON|BLUE MOON]] took place on the planet.{{Ref/Game|Halo 5: Guardians Limited Edition|[[Halo 5: Guardians Limited Edition dossiers#Linda-058|Dossier files]] - Linda-058}} Eridanus II was [[Battle of Eridanus II|attacked]] and [[glassing|glassed]] by the [[Covenant]] in [[2530]] and the UNSC abandoned the planet.{{Ref/Novel|FS|Page=240}}

===Post-war===
The planet was left largely intact, enabling rehab pioneers and original inhabitants to return hoping to rebuild.{{Ref/Reuse|encpg47}} By [[2557]], the UNSC had reclaimed and resettled the planet, as [[Nova Austin Station]] on the planet [[Cascade]] offered flights to Eridanus II that year.{{Ref/Map|H4|[[Skyline]]}}

==Government and society==
The governing of Eridanus II was under the auspices of the [[Eridanus Government]], an ally of the [[Unified Earth Government|Unified Earth Government (UEG)]].<ref name="enc44">''[[Halo Encyclopedia (2009 edition)]]'', p. 44</ref> Eridanus II has some of the best educational facilities in the Outer Colonies.{{Ref/Reuse|encpg47}} [[Martial arts|Boxing]] was outlawed on the planet.<ref>''Hunt the Truth'', Episode 03: CRITICAL CONDITION</ref>

Briefly, a [[Eridanus secessionists|group of rebels]] from the [[Secessionist Union]] took control of the planet.{{Ref/Reuse|mythos}}

===Culture===
Children on Eridanus II, at some schools, can play [[gravball]].{{Ref/Reuse|FoRpg21-25}}

===Silver Timeline===
{{Notice/Silver|category=no}}
{{Main|Eridanus II/Silver}}
Originally uninhabited, Eridanus II was settled as a part of the [[Reach for Life project]]. The [[Reach for Life installation]] on Eridanus II was one of only six to survive its pilot stage, becoming a fertile forest built into an otherwise hostile planet. It was where [[John-117/Silver|John-117]] was born and lived for the first several years of his life, at one point discovering a [[Forerunner]] [[keystone]] in a cavern near his home. His parents were the leaders of the Eridanus II colony.{{Ref/Film|Id=Emergence|TV|Episode=[[Emergence]]}}{{Ref/Film|Id=Homecoming|TV|Episode=[[Homecoming (TV Series)|Homecoming]]}}
