Editing Fireteam Osiris

After Fireteam Osiris returned to ''Infinity'', Lasky ordered for the fireteam—along with Commander [[Sarah Palmer]] and Halsey—to travel to the Sangheili homeworld of [[Sanghelios]] to utilize the planet's inactive Guardian to pursue Blue Team. Vale and the rest of Osiris were taken to the planet's surface via {{Pattern|Kmiro'sish|Lich}}, where they were tasked with finding Arbiter Thel 'Vadam while he was leading the Swords of Sanghelios against the [[Sanghelios global war|invading]] remnants of 'Mdama's Covenant at the [[Elder Council Chamber]] in [[Nuusra]]. As Osiris engaged Covenant forces, Palmer had [[Mahkee 'Chava]] deploy two [[HRUNTING/YGGDRASIL Mark IX Mantis|Mantises]] for the Spartans to utilize in clearing out the Covenant warriors at the Elder Council Chamber. Upon arriving at the chamber, Osiris battled the Covenant forces assaulting the building and fought their way inside, where they meet up with 'Vadam. With Osiris' help, the Swords of Sanghelios eliminated the Covenant forces at the Council Chamber. Moments later, 'Chava arrived in a Phantom and extracted the Arbiter and Spartans.<ref name="sos">'''[[Halo 5: Guardians]]''', campaign level ''[[Swords of Sanghelios (level)|Swords of Sanghelios]]''</ref> Traveling to the Swords of Sanghelios' encampment at Nuusra, Osiris worked together with Halsey, Palmer, and 'Vadam to formulate a plan to utilize the Guardian. 'Vadam, recognizing Locke as the ONI agent that had planned to assassinate him in the Covenant War, was initially reluctant to move his forces to assist the Spartans. However, when Cortana briefly shorted out all electronics at the encampment, 'Vadam agreed to work with Locke. Osiris was tasked with locating a Forerunner [[Constructor]] at one of the Guardian's nearby support stations to allow Halsey to input commands into the construct to force it to activate the Guardian.<ref name="alliance">'''Halo 5: Guardians''', campaign level ''[[Alliance]]''</ref> Palmer flew Fireteam Osiris to the support station, but was forced to drop them off just south of the facility due to the presence of a Covenant Kraken nearby. While the Spartans provided ground support, the Swords of Sanghelios assaulted the walker from the air. While the Arbiter's flight squadrons forced the Kraken into retreat, Osiris fought their way to an ancient Sangheili temple located near the support facility. After defeating several Prometheans at the temple, the Kraken arrived at the temple, threatening Osiris' mission. As the walker neared, the Spartans boarded the Kraken and destroyed its power generator from within. Osiris fled that doomed walker and traveled into the support facility via stolen {{Pattern|D'nomlhe|Banshee}}s. Once inside the station, Osiris retrieved a Constructor, but were attacked by Promethean forces. After battling their way back to an extraction point with the Constructor, a Phantom transported them back to the Swords of Sanghelios' encampment.<ref name="enemy lines">'''Halo 5: Guardians''', campaign level ''[[Enemy Lines]]''</ref>
