Forerunner-Flood War
-97,748 BCE (approx.): A Forerunner research team discovers the Flood on G617 g1, a military team sent in later after contact is lost. The Flood escape the planet, thus beginning the Forerunner-Flood War.

-97,565 BCE: The AI known as 343 Guilty Spark is installed as the Monitor of Installation 04 (Alpha Halo).

-97,450s BCE: The Librarian discovers Earth and humanity. Work begins on a portal to the Ark.

-The Cradle of Life occurs.

-97,448 BCE (approx.): The war ends with the Halos being fired. The Flood are defeated, albiet at the cost of all sentient life still within the galaxy and untold numbers of Forerunner lives.

-97,348 BCE (approx.): The indexed species are returned to their planets, At some point humans are designated as Reclaimers, intended to ‘reclaim’ the Forerunner’s legacy, the only species capable of using devices such as the Halos. However, the idea is never fully activated upon, the Forerunners realising that their time has come to an end, that it’s best that their legacy be forgotten. As Librarian once said in the Forerunner/Flood War, “we’ve been irresistable and immovable for too long. Maybe it is our turn to give.” They seemingly become extinct. The result is that while the Monitors believe humans to be aware of the Forerunners’ legacy, the reality is that they aren’t.

-The San 'Shyuum misinterpret the firing of the Halos as something to propel the Forerunners into an afterlife. They begin seeking ways to follow the “gods”’ footseps by locating and activating the “Seven Sacred Rings.”

Aftermath
-57,448 BCE (approx.): A meteor bearing Forerunner caligraphy crash lands on the world that will become known as Sigma Octanus IV.

-648 BCE: San 'Shyuum Reformers barricade themselves in the Forerunner dreadnaught on their homeworld, much to the chargrin of the Stoics. They depart from the planet, taking a significant portion of it with them. However, they have a very limited gene pool and as such, begin selective breeding. In time, the story that they fled when their planet's sun went nova becomes the accepted story.

-480 BCE: The Battle of Thermopylae occurs. An alliance of Greek city-states battles the invading Persian Empire at the pass of Thermopylae in central Greece. Vastly outnumbered, the Greeks hold back the Persians for three days in what will become known as one of history’s greatest last stands.

-June 13: Adjutant Reflex updates its thread with the text “tick tock.”

-June 14: Shortly after the deadline, Adjutant Reflex posts a cryptic poem titled “Look for the Signs, Keepers of the Flame.” A mysterious glyph is attatched to it.

-June 15: Society of the Ancients (SOTA) members, a group who look for ‘evidence’ of extraterrestrial activity on Earth, begin handing out flyers in New York, application forms including an email address. However, on the internet at least, the group seemingly doesn’t exist.

-June 16: SOTA members are spotted in Vancouver and London.

-June 17: Adjutant Reflex posts another threat titled “Macbeth”, stating that it has been attacked somehow. It announces that it will be able to deflect assault for 22 hours, giving a deadline.

-June 18: Reflex posts another thread, stating that someone stronger than him is going to defeat him.

-June 19: Reflex posts one last time (“HELP ME”) before announcing that security is failing and peril is near. References to the other entity are made, claiming how he’s a better machine. Suddenly, the messages cut off, the entity claiming that it has commandeered the matrix and “everything is within protocol.”

-June 20: A transmission is received on the forums, making reference to keys opening up “secrets of the past”, along with references to the Halos.

-June 21: AR’s symbol adorns the server, a transmission being made that hints of the Halos’ activation, even giving a transcript of the final moments before said activation.

-June 28: AR, now under the alias of Pulse (seemingly the new entity) makes a new post, referencing something “beating in the heart of the universe.”

-June 29: AR makes another post, seemingly announcing that he has no regrets. Seven minutes later, another post is made, stating “Adjutant Reflex is ended. This is a convenient matrix. For now.”

-July 4: Another glyph appears on the server, similar to AR’s one.

-July 6: Numerous adds appear on Google for a company called ‘Flood Containment Control.’ Attempts to access the links generate a recording of a phone conversation.

-July 7: The call number of ‘Flood Containment Control’ changes. A link is attatched that references ‘Flood Cleanup and the Air in your Home.’ A new recording is up.

-July 8: The number and recording change again.

-July 10: New servers open up, displaying a message hinting at the Flood’s intelligence. It warns that the fate that “we” lived is one that “you” may relive.

-July 26: A 'Star Image' and other symbols appear on the server, along with a text file titled "content_overwrite."

-August 2: The thumbnail for the Spartan Laser appears on the website. Upon clicking on it, it demands that it is waiting for sound output from the “initiate.”

-August 9: Server 4 opens on the site. There’s a recording of a conversation of the Flood’s biology, an image of a DNA sample thought to originate from a Chinese alligator, a star image that shows the “artifact location” and an image of the Boomerang Nebula, possibly where the Flood “came from.”

-August 10: A message is sent to the site, its origin claiming to be in the year 2552. It consists of both Latin and English words. The Latin words translate into “I lead humans doom of my own.” The first letter of each English word spells out GRAVEMIND.

-August 17: Server 5 opens, with a transcript concerning the uniqueness of what appears to be Earth and its inhabitants, two bi-sections of Earth, one of which appears to show the super-continent of Pangea, a Forerunner glyph and a message from something titled MB05032, claiming that it and all the answers lie in something called the Ark.

-Late August: An MSN claims that the Iris viral campaign has come to an end.

Conflict
-Mid 21st century: The first "smart" AI is developed.

-2079: Volume 49 of the Journal of Higher Dimensional Physics is published.

-Early 22nd century: Vladimir Koslov is born. He will become an advocate of returning to communism.

-22nd century: Tensions begin to mount on Earth due to overpopulation. A number of new movements form, most notably the Koslovics (supporters of Vladmir Koslov, who sought to return to the glory days of communism and eradicate capitalist influence) and the Jovian Frieden, a group supporting neo-facism that had sprung up in opposition to the communist movement.

The Koslovics gain ground on the Jovian moons, having the backing of the Unified German Republic (due to ‘worker crusades’).

-Early 2142: The Unggoy are conscripted into the Covenant.

-2160, March: The Jovian Moons campaign begins, with Jovian secessionists attacking colonial advisors stationed on Io. Three way fighting begins between the Koslovics, Friedens and UN forces. With many of Earth’s nations sponsoring these colonies, fighting spreads to Earth with many proxy battles being fought.

-June: The Jovian Moons campaign ends.

-2162: The Rain Forest Wars begin, the largest conflict since WWII. UN, Jovian and Koslovic forces battle across South America, causing widespread destruction and triggering famine. The conflict sparks smaller ones off-planet.

-The UN enacts the United Security Acts of 2162 and Homeland Security Act of 2162.

-2163, December: The Argyre Plantia Campaign begins, one of the many stem-offs from the Rain Forest wars. UN, Jovian and Koslovic forces clash on Mars. It marks the first extra-terrestial deployment of marines, resulting in unprecedented success for the UN. It’s likely that at this point the UNSC (United Nations Space Command) is formed, specialising in interplanetary operations.

-2164: The beginning of what will become known as the Interplanetary War. The UN begins a massive build up of their forces as well as increasing propaganda. UNSC forces systamaticly crush all Koslovic and Jovian forces on Earth and then defeat them systematicly throughout the solar system.

-The classic military novel A Soldier’s Tale: Rainforest Wars is published.

-2170: The war ends, the result being UN victory. All of Earth’s nations are brought under its leadership, resulting in a central world authority and government. In the aftermath of the war however, there’s a surge in population growth (post war ‘baby boom’) and South America is sufferring from widespread famine and a crippled infrastructure.

Expansion
-2291: A group of military researchers develop the Shaw-Fujikawa Slipspace Drive, providing practical means for humans to travel astronomical distances at faster than light travel without side effects (eg time dilution).

-2310: The Slipspace drive is revealed to the public for the first time, installed in the first line of colony ships. Given that conditions on Earth have been deteriorating due to overpopulation, hitching a ride out of the Solar System becomes an attractive option and there were many volunteers. The military is assigned to oversee the eager colonists, as their lack of activity is allowing funding to go to waste.

-2362, January 1: The Odyssey is launched, the first ship sent to colonise planets outside the Solar System. Many other ships follow in its wake. Colonists begin to terraform numerous planets.

-2390: The colonization of the Inner Colonies is fully underway. There are 210 human-occupied worlds in various stages of terraforming. The population burden is largely stabilized.

-Early 2480s: Michael Stanforth is born.

-2488: By this stage Harvest has the highest per capita agricultural productivity rate of any colony.

-2490: By this stage, 800 worlds had been colonised by humanity situated through the Orion Arm and the Milky Way. Two distinct groups of planets form; the Inner Colonies (the earliest settlements and economic and political strongholds) and the Outer Colonies (less populated and the main sources of raw materials). It is in this period that the planet Reach becomes the UNSC’s primary naval yard and training academy.

The New Age
-Early 2490s: Catherine Elizabeth Halsey is born.

-Early 2510s: Some of the children who will be entered into the Spartan II Program are born.

-2511: John is born

-On Onyx, Forerunner artifacts are found during routine excavations in Zone 67. ONI take imidiate interest in the planet, classify its existence and shut it off from all outsiders.

-2512: A geological survey team on Sigma Octanus IV finds rocks with odd compositions-these were introduced from meteor impacts roughly 60,000 years earlier.

-2513: The second insurrection in the Eridanus System, led by Colonel Robert Watts, is surpressed by the UNSC in Operation: Trebuchet. Watts is then driven into the local asteroid belt.

-2516: Jacob Keyes enlists in the Luna OCS Academy.

-Jane Shebura is born, {Tara Izira is born}.

-2517: Keyes’ CO performs a test to make slipspace jumps more accurate. Due to over-eagerness and poor mathamatics it goes awry, costing the lives of fourteen Ensigns and putting Keyes in rehabilitation for plasma burns. Despite overwhelming evidence, he refuses to testify. The lieutenant is still court-martialed just the same though.

-Early July: Jacob Keyes graduates from the OCS.

-Early August: Much against his will, John is forced to play chess. He easily beats every opponent that comes his way.

-August 17: Lieutenant Jr. Grade Jacob Keyes is awakened by AI Toran from cryogenic sleep along with Dr. Catherine Halsey onboard the Han in the Eridanus System. Halsey and Keyes descend to the surface of Eridanus II to meet John in a playground in Elysium City. He’s given a simple test to determine whether he will be one of 75 out of 150 possible candidates to become a Spartan II. He passes with flying colours.

-September: Keyes begins to gain insight into the nature of Halsey’s work. He’s therefore transferred to the UNSC Magellan with a promotion to Lieutenant for his trouble.

-September 23: Project: SPARTAN II begins on Reach with 75 conscripts. This is part of an effort to develop an effective, surgical military team in order to prevent rebellion in the Outer Colonies. The children are briefed by Halsey and sent to bed, fatigued from slipspace travel.

-September 24: Training begins for the Spartan II recruits under Chief Petty Officer Franklin Mendez. The day includes runs and excercises with Mendez and Deja letting the children view the Battle of Thermopolye. In the game ‘Ring the Bell’ John-117 is paired up with Samuel-034 and Kelly-087. Due to John’s lack of teamwork they come last in the exercise and are denied dinner.

-September 25: Training progresses much the same way. Deja shows the children some (holographic) wolves stalking and bringing down a moose. ‘Ring the Bell’ is played again. John, Kelly and Sam grasp the concept of teamwork and finish third.

-2519, July 12: The Spartan IIs embark on an exercise of navigation, having to find their way to a Pelican dropship which will take them back to base. The last one to make it however, will be left behind. John is determined that this won’t happen.

-The Spartans link up and march towards the extraction point. They reach it and find the dropship, guarded by two ununiformed soldiers. Given their lack of identification, John and the other Spartans think that they’re rebels. They knock them out and all fly off in the dropship.

-John is debriefed by Mendez and Halsey. Although Mendez is pissed at his actions, Halsey is impressed with his innovation. He’s made Squad Leader.

-2520: The UNSC Spirit of Fire is refitted as a warship.

-2520s: Work begins on the Sparrowhawk.

-Mid 2523: Courtesy of increasing Insurrection activity, Jilian al-Cyngi's workload begins to shoot up.

Contact Harvest
-2524, Mid June: Insurrectionists hit the luxury liner National Holiday above Reach, detonating explosives against its hull. The ship plummets into Reach's atmosphere, burning up via re-entry. ONI manages to portray it as a tragic accident.

-June 16: A UNSC Marine Corps force launches a raid against Insurrectionist forces on Tribute. Although the rebels are neutralised, the bombs they planeted are not, resulting in civilian and Marine casualties.

-August 7: Marcille passes away.

-August 10: Avery Johnson arrives in Chicago, Earth, after the botched operation on Tribute. He goes to visit his aunt Marcille, only to find that she passed away three days ago. In grief, he goes on a drinking spree.

-2525: Antonio Silva joins the UNSC Marine Corps. He’s given the rank of a commissioned officer and placed in command of an ODST platoon.

-Early January: The Prophet of Restraint impregnates a female San 'Shyuum, despite his defective genes not allowing him to do so. With the mother refusing an abortion, a scandal starts brewing over the issue.

-January 2: Johnson and co. begin training Harvest's Colonial Militia.

-January 16: The militia goes on another march, this time with 25kg rucksacks. In the aftermath, Johnson and Ponder attend Harvest's Solstice Celebration. Johnson is briefed by al-Cygni as to why he and Byrne are here; to prevent Insurrection attacks on UNSC freighters.

-January 17: The Minor Transgression attacks another human ship (the Bulk Discount), said human ship having the Walk of Shame in support and hosting not only Johnson and Byrne but also an arsenal of weapons. The aliens are repelled (though Johnson recieves a fractured skull) and the ship destroyed, though Dadab and Lighter Than Some are able to escape in a escape pod after making a report on the relics they've found.

-Wallace A. Jenkins, Forsell, Wick and Andersen begin target practice.

-The Ministry of Fortitude holds a statistic-based meeting. The Minister of Fortitude takes stimulants to help him through the ordeal.

-January 18: Fortitude wakes up, the 'hangover effect' of the stimulants taking hold. The Vice Minister of Tranquility alerts him to the Luminary detections made by Minor Transgression. They resolve to use them to usher in an Age of Reclamation and secure their position as the next trio of Heirarchs.

-The Walk of Shame is sent to Reach to request that FLEETCOM send a battle group in the event of first contact escalating into bloodshed.

-January 19: Johnson regains conciousness and is debriefed by Nils Thune and al-Cygni. Johnson resolves to accelerate the militia's training.

-January 20: Sif analyses what she knows concerning what's happened in the last four days. Mack answers the questions for her, informing her as to his true nature in regards to the AI Loki.

-Late January: Dadab and Lighter Than Some are picked up by the Brute controlled Rapid Conversion.

-Early Feburary: The Prophetess of Obligation gives birth to a pair of triplets.

-February 3: One of Harvest's orbital platforms detects an object of unknown origin ( possibly the Rapid Conversion) entering the system. All contact is lost soon after. After failing to re-establish contact, the Colonial Military Administration sends the Argo, a UNSC scout ship, to investigate.

-Mack begins to show signs of Rampancy.

-Feburary 9: Just after the militia finishes a training excercise, Rapid Conversion arrives at the planet. It scans symbols on a freighter, interpreting them correctly as a peace offerring. They accept it, glyphs indicating the presence of an Oracle on the planet.

-At the militia's victory dinner, Ponder informs them of the recent events of first contact and how they are to deal with it if necessary.

-February 11: The Jiralhanae meet with the delegation Thune's provided. Despite the difficulties of communication, it's made clear that the aliens want the planet ceded to them so that they may obtain the relics detected. With automatic fire suddenly ringing out, events get out of hand, both sides opening fire at each other. The battle breaks off, Maccabeus sending a message to High Charity.

-A drone encounters Walk of Shame.

-Mid February: The San 'Shyuum have their ceremnony where their offspring are shown. Fortitude and Tranquility visit the Philologist, seeking the blessings of the Oracle. The Oracle reveals that the glyphs on Harvest are Reclaimers; seemingly decendents of the Forerunners. Fortitude decides that the Reclaimers/humans must be erradicated, as the knowledge of Forerunners being left behind could shatter the Covenant's faith and cause it to splinter. They send a message to Maccabus to erradicate Harvest's inhabitants.

-Thune makes a public broardcast across Harvest, informing its citizens of the alien threat. Its met with general disbelief and anger at being left out of the loop, given his "dealings with aliens". Suffice to say, his evacuation orders are largely ignored.

-Feburary 19: Having recieved Fortitude's message, Rapid Conversion descends upon Gladshiem, erradicating its outer homesteads. Simultaniously, Dabab leads the unggoy into the Tiara.

-February 22: The militia aid in the evacuation of Gladshiem. Johnson and Byrne take out a Warthog to distract the Covenant dropships. Maccabus has his leg crushed by the Warthog in the process. On the Tiara, Dabab gains access to some of Sif's circuts. Lighter Than Some is taken over to the station, keeping it safe from the yaname'e who wish to return to their role of maintenance. Lighter Than Some contacts Loki, the latter realising that the aliens are looking for something called an Oracle; a powerful networked intelligence. Loki relays this info.

-Upon arriving at Utgard, a confrontation develops between Thune and al-Cygni, the latter revoking Thune's status. The 'transition' is not without violance however, Ponder being shot through the spleen.

-February 23: Ponder takes a fake Oracle to the landing zone for the cruiser. It's a trap however, Harvest's mass driver crippling the cruiser as crates bearing refugees head up to the Tiara. Ponder is killed in the process however.

-Maccabus orders Dadab and the unggoy to hold the line; a task not made easier given that, due to questioning the need for genocide and refusal to offer the humans a place on the Great Journey, Light Than Some has reactivated the Tiara. Dadab finds himself asking the same questions and disobays Maccabus' orders. Maccabus himself meets his end, courtesy of Tartarus challanging him to a duel.

-Avery leads one team of militia to secure the Tiara while Byrne and his platoon remain on Harvest to distract the dropships. The Tiara is secured, with all of the aliens onboard killed. After the crates are attatched to propulsion pods, the Tiara is destroyed by the Mass Driver.

-Fortitude, Tranquility and the Philogist are crowned as the new Heirarchs, namely the Prophets of Truth, Regret and Mercy respectively. They declare the 9th Age of Reclamation and a holy war against humanity.

-April 20: The Argo’s last transmission confirms that it entered the Epsilon Indi System. All contact is lost soon after, courtesy of the Covenant destroying it (Mack couldn't warn it fast enough). The CMA then sends a battle group to investigate.

-April 21: Mack reflects on what happened with the Argo. The Covenant pick up his signal. They start destroying objects to find and destroy him.

-April 22: While exercising in the gym of the Atlas, John-117 is attacked by four ODSTs as part of an exercise to test his new abilities. He ends up inadvertently killing them.

-September 12: The Spartans receive their first “official” mission; to infiltrate the rebel base in the Eridanus System asteroid belt and capture Colonel Robert Watts. John is promoted to the rank of Petty Officer Third Class and selects Sam-034, Linda-058, Kelly-087 and Frederic-104 to join him on the mission.

-September 14: John and his team successfully infiltrate the rebel base. Dispatching anyone who gets in their way, they successfully find Watts, eliminate his guards and sedate him, although John is wounded in the process. They escape with Watts in a Pelican as Sam detonates some C-12 charges, exposing the base to the vacuum of space.

-October 4: Mack burries his data core along with Sif's deep into Harvest's soil so that the glassing won't reach them.

-October 7: The UNSC battle group enters the system and discovers that the once lush world of Harvest has become a cratered, barren desert with presumably all 3 million lives lost. They find the Covenant ship responsible for the colony’s destruction, which engages them. The Aradbia and Vostpk are quickly destroyed. Only the badly damaged [[UNSC Heracles|Heracles escapes. It bears a pre-translated message from the Covenant; “Your destruction is the will of the gods and we are their instrument.”

-October 11: ONI goes over the data that the Heracles retrieved, including a number of transmissions from Mack.

-November 1: The UNSC is ordered to full alert. Vice Admiral Preston Cole begins massing the largest space fleet in human history to retake Harvest.

-November 26: The Spartans learn the location of their destination.

-November 27: En route to the testing facility, the UNSC Commonwealth is attacked by a Covenant ship. Both ships open fire, although while the Covenant ship’s pulse lasers succeed in doing damage, the Commonwealth’s Archer Missiles are completely ineffective against the enemy’s shield. The MAC Cannon is deployed but while it damages the Covenant ship it fails to destroy it, allowing them to respond with guided plasma. As a last ditch effort Longsword fighters deploy a timed nuke, damaging the ship enough to force it to retreat.

-The Spartans receive MJOLNIR Mark IV armour and begin training, their senses and movements radically augmented. However, the Covenant ship returns, cutting the training short. With the Commonwealth’s weapon systems down, John proposes that they destroy it from the inside. Suiting up in Mark IV EVA variant suits, he, Sam and Kelly successfully board the Covenant ship, carrying an Anvil-II-air-to-surface missile. Dispatching Jackels that get in their way (although Sam is injured). They set it to detonate at the ship’s reactor. Sam stays behind to ensure its detonation; his suit having been breached, he’d die from decompression in the vacuum of space. John and Kelly escape before the ship is destroyed, taking Sam along with it.

-John, Kelly and Sam destroy a Covenant ship by carrying an Anvil-II air-to-surface missile and detonate it inside the ship’s engine room, destroying the ship. Due to damage sustained to his armour, Sam is unable to escape, thus volunteering to stay behind and detonate the warheads.
