The following data-logs were compiled by Sheila, UNSC shipboard A.I of the Marathon-Class Cruiser; Destiny's Harbinger, following the events of Generation 6:

Six months after the events that saw the end of Draetheus and Benedict's schemes and the restoration of the time-space continuum, subjects Kittiana Calypso Youngblood, Gavin McReed and Endymion disappeared off the radar during a scouting run concerning a mystical energy signature detected below the Earth's surface. Rescue teams were sent within 12 hours of their disappearance.
Within this time, the UNSC Destiny's Harbinger was contacted by FLEETCOM and the ship was ordered to arrive at designated coordinates to oversee the discovery of a newly found Forerunner artefact. After the Harbinger arrived at the location, the UNSC had already set up a significant presence there. The "artefact" was an artificial planet: a Forerunner shield world encased in a metallic shell (later discovered to be named Haven). Any and all attempts to gain access to the planet had been unsuccessful.
A plan was soon devised and carried out by Aaron-157. The Spartan lead Fireteam Aqua towards what was recently discovered to be the "entrance" to the shield world, albeit locked. As the Spartan's pelican dropship approached the entrance, Covenant forces arrived on-site via Slipspace and a naval battle took place between the UNSC and the Covenant, at which point the entrance to Haven opened up and Aaron-157's Pelican was pulled into the shield world via gravity beam (it was later theorised that the naval battle triggered this phenomenon).
Covenant forces were quickly dispelled, however further attempts to access Haven were unsuccessful for the next three months.

Three months later, after Kittiana, Gavin and Endymion were rescued from a parallel dimension, an immediate rescue operation was conducted by Kittiana to recover Fireteam Aqua. Enlisting the help of alien bounty hunter; The Freelancer, Kittiana's team was able to gain access to the sheild world when they too approached the entrance, the same time at which another Covenant strike fleet arrived on-site. The UNSC Destiny's Harbinger was pulled into the planet along with them along with two other UNSC ships and two Covenant ships.
Once on the surface of the Earth-like world, all three UNSC ships began to establish bases as well as search for three structures located at equidistant intervals around the globe known as "Cartographers"; map rooms each of which contained a third of Haven's full map. All three structures were located and using security footage I obtained from one of the cartographers, we managed to locate and rescue Fireteam Aqua who had been captured and placed in suspended animation by Haven's native sphere-shaped sentinel robots.
<>
By analysing the completed map of Haven, I was able to discern the location of a control room, which was located not too far from one of the cartographer structures. The UNSC managed to gain access to the control room, albeit with heavy resistance from the sentinels. By inserting me into the mainframe, I was able to deactivate Haven's outer shell, and the world was rendered fully accessible to UNSC cavalry. Covenant presence on the planet was quickly diminished with the arrival of backup.
<>
After successfully establishing bases on one third of the planet, the Covenant arrived again in full force. The conflict quickly escalated into a territorial war between the Covenant faction lead by the Sangheili supreme leader Rha Mantakree, the Sentinels and the UNSC over occupation of Haven. Spartan Bruce Marshall, the demolitions expert of Fireteam Aqua was rendered KIA during the escalation.
<>
The subject Eli, understood to be one of Dan's brothers had an unexpected arrival on-site to assist with establishing bases and then later on, join Fireteam Aqua in defending the Control room. Rha Mantakree's forces lead by Covenant Spec Ops Commander Uva 'Nadom stormed the Control Room and dealt a severe blow to the UNSC presence established there. Fireteam Aqua were able to eliminate Uva 'Nadom, however Eli was killed in the conflict. Fireteam Aqua was eventually driven out of the Control room due to the arrival of sentinels.

Reports indicate that Aaron and his team arrived on the station that had sent out the distress beacon, where they made contact with the Rogue Syndicate lead by Heather. Other members included rogue Spartan Zara Khan, long thought dead Max-503, a Hypersoldier and a demonic counterpart of Gavin's Ghost Rider form. After a brief confrontation, the Syndicate managed to escape.
Further intel and investigation lead Aaron and his team to a new fortress under construction as well along with another Purge Cannon. There they were joined by the rest of Fireteam Aqua where they were successful in disabling the fortress.
<>
Fireteam Aqua tracked the Syndicate to Delta Halo, where they were shot down. The team was reportedly forced to have resorted to guerrilla-warfare tactics where they managed to make repairs, deal significant blows against Heather's squad (eliminating the Hypersoldier and Zara) and establish contact with FLEETCOM to radio for backup. Once backup had arrived, the other half of Fireteam Aqua were reassigned to Haven where the battle was tipping in the favour of the Covenant. Aaron and his team were successful in driving Heather and Max-503 off the ringworld, while Gavin had successfully imprisoned his counterpart in a soul gem. Spartans Nicholson and Green were amongst the casualties in these series of events. Endymion's whereabouts unknown.
<>
Aaron-157, Spartan Sebastian Duarte, Kitty and Gavin soon made contact with and accompanied Thor to Asgard where they used the Bifrost to gain access to Oblivion. From there, they retrieved the imprisoned Dan and left.
<>
Aaron and his team were then re-assigned to Haven to join the battle. Numerous territorial operations were conducted by the Spartan and ODST battalions to take down Covenant bases while re-establishing our own. Much of this progress was hindered by the constant presence and intervention of the sentinels.
Battle-net intel later unveiled that the Covenant were in search of another control room that supposedly granted access to a super-weapon hidden on the planet. Rha 'Mantakree's right hand man, Iha 'Luduk was reported to have been dispatched to a certain location to activate the weapon. Fireteam Aqua was assigned to a mission to assassinate Iha Luduk. The intel turned out to be the hoax and it was later discovered that the actual control room was located at the planet's dormant core, that Rha 'Mantakree had accessed in secret. Using the super-weapon, 'Mantakree destroyed the human colony world designated "Harmony". It was later reported that 'Mantakree was driven out of the core by sentinel forces.
<>
Haven's failsafe activated, causing the metal casing to re-engage over the planet, and the planet itself suspended in slipspace which prevented communication with the outside world.
Both UNSC and Covenant forces began to redirect all of their resources to occupying and taking control of a structure designated the "Master Terminus" through which the Core of Haven could be accessed. Aaron-157 lead Fireteam Aqua and Kitty to continue their mission and assassinate Iha 'Luduk. The mission was successful through boarding action of 'Luduk's ship. Spartan Robert Bobbinson, second in command of Fireteam Aqua was rendered KIA during the mission.
A mission was later conducted by the Captain of the Destiny's Harbinger: Ronald Whitley to intercept a Covenant strike team on their way to the Master Terminus and commandeer their ships. The mission was lead by three Spartan Fireteams including Fireteam Aqua in Broadsword fighter squadrons. Mission resulted in success. Nephilim Erin was introduced into Fireteam Aqua.
Kittiana, Dan and Erin were sent on a rescue operation to recover survivors of the destruction of a UNSC base. Mission resulted in failure; survivors were rendered KIA while Kittiana, Dan and Erin were captured. It was understood that Kittiana and Dan were tortured soon after, to disclose information about the UNSC's battle plans. During the torture, Dan was reported to have returned to Oblivion. Aaron-157 lead Fireteam Aqua and Gavin on a rescue mission which resulted in success, recovering Kittiana and Erin. After a series of brief conflicts, all UNSC forces had gathered at the canyon housing the Master Terminus.
Sentinel, Covenant and UNSC space, air and ground forces clashed and struggled for hours over control of the Master Terminus, during which Covenant Field Marshal Ova 'Nadom was eliminated. A plan devised by Erin managed to provide us with the window needed to occupy the Terminus, however the arrival of millions of Sentinels resulted in most of the UNSC and Covenant forces being destroyed. By the time this threat was diffused, Covenant forces outnumbered the UNSC. Fireteam Aqua was instructed to retreat into the Master Terminus, reach the Core, bring Haven back to normal space, disengage the planet's shell and make establish contact with FLEETCOM for backup. During the UNSC's last stand on Haven, the Destiny's Harbinger was the last ship to fall along with Captain Whitley and his crew.
The last of Covenant forces gained access to the Terminus and it became a race against time to access the core. Aaron-157 made a final stand against the Covenant legion to buy the rest of us time to access the Core. Our final mission was successful, where the timely arrival of UNSC backup and some reprogrammed Sentinels ensured our survival. Rha 'Mantakree and his Covenant were completely destroyed. Aaron-157 was rendered KIA during his last stand. Upon exiting the planet, Kittiana was also rendered KIA during a surprise ambush by Heather. Heather was also eliminated during this conflict.
