'''Gao''', known to the [[Forerunner]]s as '''Edod''', is a remote [[human]] [[Outer Colony]] in the [[Cordoba system]] that survived the [[Human-Covenant War]]. While originally under the administration of the [[Unified Earth Government]], the world was a major component of the [[Insurrection]], and gained its independence during the [[Human-Covenant War]]. As such, both the people and the [[Gao Republic|colonial government]] of Gao maintain a strong sense of national identity and anti-UEG sentiments are commonplace.{{Ref/Novel|LL|Chapter=14}} The planet's [[Montero]] region was home to a [[Montero Cave System|vast cavern system]] — in fact [[Covert Support Base 4276|an artificial Forerunner construct]] designed to support the [[Maginot Line]].{{Ref/Novel|LL|Page=36 (Google Play edition)}}

==Overview==
===Topography===
Gao is a lush, jungled planet;{{Ref/Novel|LL|Page=189 (Google Play edition)}} viewed from space, the planet is largely mottled green fading to gray at both poles, which are covered by large deserts. Gao's jungles and caverns support a rich ecology with numerous native species (including [[saurio]]s, [[frilled salamander]]s, [[idjom]]s, [[jungaloon]]s, [[ribbon-snake]]s, [[no-shell snail]]s, [[speckled jungle dragon]]s and [[glowfish]]), while the planet's polar barrens are inhabited by great gray apes.{{Ref/Novel|Id=ll72|LL|Page=72-73 (Google Play edition)}}

==History==
===Rise of humanity===
During the [[Insurrection]], Gao openly supported the [[Insurrectionist]]s.{{Ref/Novel|LL|Page=10 (Google Play edition)}} At an unknown date, the UNSC [[Blockade of Gao|blockaded]] Gao for a year.{{Ref/Novel|DW|Chapter=Epilogue}}

===Post-war===
Following the [[Human-Covenant War]], Gao remained highly independence-minded and sought to strengthen its ties with nearby colonies, such as [[Venezia]], which was only nine light years away{{Ref/Novel|SS|Page=87}} rather than the UEG.{{Ref/Novel|Id=c5|LL|Chapter=5}}

[[File:Halo Last Light cover.jpg|thumb|250px|Veta Lopis and UNSC forces in the Montero Cave System.]]
In [[2553#May|May 2553]], the [[UNSC Marine Corps]] [[717th Xeno-Materials Exploitation Battalion]] protected by [[Blue Team]] arrived at the planet to recover a [[Forerunner]] [[ancilla]] in the [[Montero Cave System]]. The UNSC subsequently declared the cave system off-limits to outsiders, but civilians continued to sneak into the caves anyway in search of rumored miracle cures; soon after, an increasing number of these civilians were found brutally murdered. With tensions heightening between Gao's government and the UNSC, [[Special Inspector]] [[Veta Lopis]] of the Gao [[Ministry of Protection]] was assigned with investigating the serial killer on [[2553#July|July 2, 2553]]. Meanwhile, the [[Insurrectionist]]-minded Gao politician [[Arlo Casille]] allied with the [[Covenant remnant|ex-Covenant faction]] known as the [[Keepers of the One Freedom]] to prevent the UNSC from gaining control of the Forerunner technology in the caves. Seeking to drive out the UNSC forces without forcing Gao itself into a war, Casille smuggled the Keepers on the planet,{{Ref/Reuse|c5}} where they attacked the UNSC research battalion, resulting in several days of fighting in the Montero region. In the end, the UNSC forces evacuated from the planet with the Forerunner AI, [[Intrepid Eye]], while destroying the Montero Cave System with a [[HAVOK tactical nuclear weapon]]. Casille chose to cover up the true source of the nuclear explosion rather than face pressure to enter into a war with the UNSC he doesn't want.{{Ref/Novel|LL|Chapter=28}}

Over the next several months, the vengeful Keeper [[dokab]] [[Castor]] engaged in extensive [[piracy]] against Gao. The desperate Casille made a deal with [[Dark Moon Enterprises]] where in exchange for allowing Dark Moon the use of one of Gao's labs, Dark Moon would provoke the UNSC into dealing with the Keeper problem. After the family of murdered admiral [[Graselyn Tuwa]] were brought to the lab for experimentation, Casille decided to sanction the experiments rather than admit to the UNSC what was going on and face a possible invasion. After killing the Tuwas and cutting out their organs for [[Intrepid Eye]]'s [[bioweapon]] plot, Dark Moon deposited the bodies on the Keepers' [[Salvation Base]] to frame the murders upon them. As planned, the UNSC hit the Keepers hard in [[Operation: RETRIBUTION]], destroying Salvation Base and ninety percent of the forces stationed there. However, Veta Lopis and her [[Ferret]] team recovered the bodies and realized that the scene had been staged. Forensic evidence led the Ferrets and Blue Team back to the lab on Gao which had by that point been destroyed by Castor who had learned the location from captured Dark Moon operatives. The Ferrets and Blue Team confronted Casille who realized that Gao had been set up to take the fall the same way the Keepers had. Casille pointed the Ferrets and Blue Team towards [[Pinnacle Station]] above [[Meridian]], as the station's AI [[Sloan|Administrator Sloan]] had suggested Dark Moon to him and was apparently involved in the setup.{{Ref/Novel|HRet}}

==Government and society==
Gao was an insurrectionist hotbed as early as [[2526]],{{Ref/Novel|SS|Chapter=11}} with the [[Gao Liberation Force]] forming around then.{{Ref/Novel|SS|Chapter=5}} Eventually, the colony would go "free"{{Ref/Novel|LL|Page=194}} and form its own government; the [[Gao Republic]], an entity that considered itself sovereign.{{Ref/Novel|LL|Page=232 (Google Play edition)}} A second insurrectionist faction named the [[Committee to Preserve Gao Independence]] formed in 2553 after the UNSC began occupying parts of the planet.{{Ref/Novel|LL|Chapter=14}}

==Trivia==
The planet may be named after [[Wikipedia:Gao|a city of the same name]] in Mali.
