'''Chi Ceti IV''', referred to by the [[Covenant]] as '''Chelav''',{{Ref/Novel|Id=HSS9|HSS|Chapter=9}} is a [[human]] [[Outer Colonies|Outer Colony]] in the [[Chi Ceti system]], orbited by two [[natural satellite]]s. A distant red nebula is visible from the system.{{Ref/Novel|Id=TFoR12|TFoR|Chapter=12}}The planet has a top-secret installation on its surface, the [[Damascus Materials Testing Facility]] in [[Vhalkem]],<ref>[http://blogs.halowaypoint.com/Headlines/post/2013/07/10/The-Halo-Bulletin-71013.aspx ''The Halo Bulletin 7.10.13'']</ref> where the [[MJOLNIR Powered Assault Armor/Mark IV|Mark IV MJOLNIR armor]] and the [[MJOLNIR Powered Assault Armor/EOD variant|MJOLNIR EOD variant]] were developed.{{Ref/Reuse|TFoR12}}{{Ref/Book|Id=ENC94|Enc09|Page=94}}

==History==
===Colonization===
Chi Ceti IV was first [[Human colonies|colonized]] by modern humanity in [[2430]].{{Ref/Reuse|Enc22P49}} Sometime thereafter, the [[Office of Naval Intelligence]]'s [[Materials Group]] established the [[Damascus Materials Testing Facility]] in the region of [[Vhalkem]].{{Ref/Reuse|TFoR12}}

===Battle of Chi Ceti IV===
{{Main|Battle of Chi Ceti}}
On [[2525#November|November 27, 2525]], the [[Covenant]] {{Pattern|Zanar|light cruiser}} ''[[Unrelenting]]'' arrived in the [[Chi Ceti system]]. The [[UNSC frigate|frigate]] {{UNSCShip|Commonwealth}} drove off the former vessel, though both ships were heavily damaged. ''Commonwealth'' remained in orbit as the [[SPARTAN-II Program|Spartan-IIs]] received their [[MJOLNIR Powered Assault Armor]] from the Damascus Materials Testing Facility.{{Ref/Reuse|TFoR12}}{{Ref/Novel|Id=TFoR13|TFoR|Chapter=13}}

Later that day, the Spartans were deployed from the frigate toward a hole that had been blasted into ''Unrelenting''{{'}}s hull in an attempt to destroy the vessel from within. Only three Spartans, [[John-117]], [[Kelly-087]], and [[Samuel-034]], arrived at the enemy vessel, which they then boarded. Shortly thereafter, Samuel's armor was damaged, leaving him unable to return to the ''Commonwealth''. He stayed behind and detonated an [[ANVIL-II Air-to-Surface Missile|ANVIL-II missile]], killing himself and destroying ''Unrelenting''.{{Ref/Novel|Id=TFoR14|TFoR|Chapter=14}} When the planet was compromised by the Covenant, the Damascus Testing Facility and a nearby [[United Nations Space Command|UNSC]] training center were abandoned.{{Ref/Book|Id=ENC298|Enc09|Page=298}}

===Return of the Covenant===
A Covenant force returned to the Chi Ceti system in [[2527]] and attacked Chi Ceti IV.{{Ref/Reuse|Enc22P50}} However, the attackers were either repelled or departed the planet without destroying the Damascus Materials Testing Facility, which was reactivated at a later date.{{Ref/Book|Id=VIS166|H4EVG|Page=166}}

===Post-war===
Chi Ceti IV survived the war and continues to support the UNSC, developing several [[MJOLNIR Powered Assault Armor (GEN2)|MJOLNIR GEN2]] armor variants such as the [[MJOLNIR Powered Assault Armor/Soldier|Soldier]] variant at the Damascus Facility.{{Ref/Reuse|VIS166}} One of the planet's moons, [[Muroto]], is now used for mining purposes by the [[Office of Naval Intelligence]].{{Ref/Reuse|VIS220}}
