'''Alluvion''', also known as '''Bhaakto III''',<ref name="Halo Channel">''[[Halo Channel]]'': Encyclopedia</ref> is the [[planet|third planet]] in the [[Bhaakto system]]{{Ref/Reuse|universe}} and a [[human]] [[Outer Colony]] of the [[Unified Earth Government]].<ref name="HE7">''[[Halo: Escalation]]'', [[Halo: Escalation Issue 7|Issue #7]]</ref><ref name="ho9">''[[Halo: Oblivion]]'', Chapter 9</ref>{{Ref/Reuse|Enc22P48}} Alluvion is orbited by the [[natural satellite]]s [[Fallow]] and [[Falgo]]. Once home to millions, Alluvion was [[Glassing|glassed]] by the [[Covenant]] in [[2543]] during the [[Human-Covenant War]].{{Ref/Reuse|Enc22P50}} By [[2554]], Alluvion has been recolonized.{{Ref/Reuse|universe}}

==Overview==
===Topography and climate===
Prior to being [[glassing|glassed]], Alluvion had vast oceans and a moderately tropical climate. It also suffered from aggressive tidal forces due to its moon [[Fallow]].{{Ref/Reuse|universe}}

==History==
===Rise of humanity===
Alluvion was colonized by the [[Unified Earth Government]] in [[2412]] as a border world and prominent waystation between the [[Inner Colonies]] and the emerging [[Outer Colonies]].{{Ref/Reuse|universe}}{{Ref/Reuse|Enc22P48}} By tradition, the colonization of Alluvion was considered to be start of human expansion into the Outer Colonies.{{Ref/Reuse|ho9}} With vast oceans and a moderately tropical climate, the planet required little [[terraforming]], though aggressive tidal activity caused by Alluvion's [[moon]] [[Fallow]] forced most population centers into the continental interiors. Alluvion was highly cherished by its residents, though the planet's history was largely uneventful until the [[Human-Covenant War]].{{Ref/Reuse|universe}}

===Human-Covenant war===
[[File:Alluvion glassed.jpg|thumb|250px|right|Alluvion is glassed by the Covenant]]
[[Covenant]] scouting patrols located Alluvion in [[2541]], though a full-scale invasion—led by [[Thel 'Vadam]]ee—did not occur until [[2542]]. During the [[Battle for Alluvion]], the [[United Nations Space Command]] was able to defend the planet with a substantial military force, keeping the Covenant forces at bay for weeks. However, a Covenant support fleet arrived and quickly severed Alluvion's critical support lines, and the planet fell shortly after.{{Ref/Reuse|universe}} Spartan [[Gabriel Thorne]]'s [[Thorne family|parents]] were [[UNSC Army]] officers stationed on the planet at the time. They, along with Alluvion's human population, died when the Covenant glassed the planet in [[2543]].{{Ref/Reuse|HE7}}{{Ref/Reuse|Enc22P50}} In the glassing, Alluvion's major population centers and [[spaceport]]s were destroyed and no sign of human activity remained on the planet by [[2544]].{{Ref/Reuse|universe}} On [[2552#September|September 26, 2552]], Alluvion was used as an example of the planets glassed by Covenant forces in [[Office of Naval Intelligence]] operative [[Jameson Locke]]'s target profile of Thel 'Vadamee.{{Ref/Reuse|h2a3}}

===Post-war===
Following the Covenant War, a recolonization support fleet of the Unified Earth Government returned to Alluvion in [[2554]]. Upon arrival, the fleet discovered a strange anomaly under Alluvion's [[Sundark Sea]];{{Ref/Reuse|universe}}{{Ref/Reuse|Enc22P48}} [[Forerunner]] shield pylons, which had previously been hidden from the colony's inhabitants, had emerged and forced back massive walls of water revealing the seafloor. Years of surveying the area revealed hidden repository containing an exotic fuel source that was believed to be capable of replacing the [[deuterium]] used to fuel human starships. The [[Liang-Dortmund Corporation]] was contracted by the UNSC to research this discovery. Liang-Dortmund's aerospace division established the [[Alluvion Research Center]] on the planet in [[2556]], attempting to directly power a number of [[Nordica V]] prototype shuttles with this energy source. However, a year into their research, the corporation's mining efforts triggered the complete withdrawal of the shield pylons, causing the sea to collapse on those who remained within the facility.{{Ref/Reuse|universe}}
