{{Status|Canon}}
The distant past is a period before the 1st millenium.

==Billions of years ago==
===Hundred billion years ago===
*In [[97,445 BCE]]; [[Forthencho]], acting as a messenger for the [[Gravemind]], stated that the [[Domain]] had been gathering information from before there were stars and had around hundred billion years of "life-patterns and living wisdom".{{Ref/Novel|Id=HSS37|Sil|Chapter=String 37}} As of [[2557#June|June 2557]] this information was believed by people who worked under [[Project BOOKWORM|Project: BOOKWORM]].{{Ref/Novel|Id=HRC23|Ren|Chapter=23}}

===Before life===
*[[The great Glow]] occurs in the galaxy.{{Ref/Novel|Id=HSS4|Sil|Chapter=String 4}}

===Billions of years ago===
*Precursors arrive in the [[Milky Way]] galaxy.{{Ref/Book|Id=Warp8|HWF|Section=Travellers|Page=8}}

==Millions of years ago==
===Over half a billion years ago===
*In 97,445 BCE, during a debate with [[Mendicant Bias]], the [[Precursor]]s were hinted by the Gravemind to have accumulating a vast reserve of rules based on experiences and disputes.{{Ref/Novel|Id=HSS24|Sil|Chapter=String 24}}

===Around 100 million years BCE===
*In [[2526]], [[John-117]] theorized that the [[Netherop species|civilization]] on [[Netherop]] may have perished around a million centuries before, alongside around a thousand centuries, and a hundred centuries.{{Ref/Novel|Id=HOC21|Oblv|Chapter=21}}

===Prior to the Forerunners being seeded on Ghibalb===
*[[The Weapon]] estimated that some data on the [[Totem Ring]]s may be older than the [[Forerunner]]s.{{Ref/Game|Id=hafh|HI|Forerunner Audio log|Detail=Ring 01 Weapon analysis}}
*The origins of the [[Mantle|Eld]] symbol is stated to predate the Forerunners.{{Ref/Book|Id=Enc22P317|Enc22|Page=317}}

===Around 15 million years BCE===
*The [[Precursor]]s seeded the species that would come to be known as [[Forerunner]]s on the planet [[Ghibalb]],{{Ref/Site|Id=HWUSForerunners|URL=https://www.halowaypoint.com/en-us/universe/species/forerunners|Site=Halo Waypoint|Section=Universe, Species|Page=Forerunner|D=12|M=11|Y=2020|LocalArchive=https://archives.halopedia.org/waypoint/www.halowaypoint.com/en-us/universe/species/forerunners.html}} branched from the same base stock that also produce ancient [[Human]]ity.{{Ref/Book|Id=Enc22P310|Enc22|Page=310}}

===Around 10.1 million years ago===
*The [[Forerunner]] [[Warrior-Servant|Warriors]] were considered the highest rate.{{Ref/Novel|Id=HSS1|Sil|Chapter=String 1}}
*Star roads were placed around [[Charum Hakkor]].{{Ref/Novel|Id=HSS3|Sil|Chapter=String 3}}
*The [[Precursor]]s choose early [[human]]s to be the next species to carry the [[Mantle]].{{Ref/Novel|Id=HSS13|Sil|Chapter=String 13}} Desiring to seize the Mantle for themselves, the early [[Forerunner]]s [[Forerunner-Precursor war|rebel against the Precursors]] and wipe them out almost entirely.{{Ref/Novel|Id=HSS15|Sil|Chapter=String 15}}
*After the Forerunners hunt down all of the Precursors in the [[Milky Way]] galaxy. The remains of the Precursors retreat into the [[Large Magellanic Cloud]]; the Forerunners' [[Warrior-Servant|Warrior]] fleets pursue them via [[probability mirror]]-reconciled [[slipspace portal]]s and proceed to finish their work.{{Ref/Reuse|HSS15}}
*A number of Forerunners who conscientiously object to the complete destruction of the Precursors in the Large Magellanic Cloud are exiled{{Ref/Reuse|HSS15}} on a barren planet within the [[Tarantula Nebula]]; these Forerunners later remain as the [[Path Kethona Forerunner|only surviving population]] of the expedition.{{Ref/Novel|Id=HSS10|Sil|Chapter=String 10}}
*In the face of extinction, most of the Precursors reduce themselves to inert powder, intending to regenerate their forms later.{{Ref/Reuse|HSS13}} However, [[Primordial|one intact specimen]] remained in deep stasis and is buried within a remote [[asteroid]] a million years afterward.{{Ref/Reuse|HSS15}}
*In the Large Magellanic Cloud; two Precursors escaped the genocide, where some Forerunners hide them; but they die and become flowers containing their genetic code.{{Ref/Novel|Id=HPOLC44|PoL|Chapter=44}}
*Following the battle in the Large Magellanic Cloud, the remaining Forerunners on the ships sacrificed themselves than return with what they did;{{Ref/Reuse|HSS15}} leaving the abandoned Forerunner ships in the Large Magellanic Cloud to slowly decay.{{Ref/Reuse|HSS10}}

===Around 9.1 million years ago===
*In the Large Magellanic Cloud; two Precursor seeds germinate.{{Ref/Reuse|HPOLC44}}
*The [[Primordial]], a dormant [[Precursor]], is said to have arrived on the edges of [[Milky Way|the galaxy]].{{Ref/Reuse|HSS13}}

===Around 1.1 million years ago===
*The [[Forerunner]] [[Rate#Theoretical|Theoretical]] known as [[Boundless]] begins to study a particular star within the [[Path Kethona]] galaxy. When she continues her work in defiance of [[Warrior-Servant|Warrior]] orders to the contrary, she is eventually prosecuted, her studies are suppressed, and she is forced to enter a [[Cryptum]].{{Ref/Reuse|HSS4}}
**A thousand years later, Boundless' Cryptum is opened and it is discovered that she has died inside due to a malfunction in the Cryptum, supposedly resulting from sabotage. Her former students discreetly dispose of her body. After Boundless' death, the entire Theoretical [[rate]] is absorbed into the [[Builder]]s.{{Ref/Reuse|HSS4}}

===Around 1 million years ago===
*In the Large Magellanic Cloud; two Precursor seeds bloom.{{Ref/Reuse|HPOLC44}}

==Hundreds of thousands of years ago==
===Around 600,000 years ago===
*A Forerunner civil war takes place, where [[Jat-Krula]] was used as a strategy, where it was bypassed by a [[Legion]] of [[Warrior-Servant|Warrior]] commanders.{{Ref/Novel|Id=HSS7|Sil|Chapter=String 7}}

===Around 150,000 years ago===
*The [[Forerunner]]s are claimed by some records to have risen as the preeminent species in the [[Milky Way Galaxy]] by advancing technological discoveries gathered from the remnants left by prior ancient races. Believing themselves responsible for the lives of all those less advanced then they, the Forerunners initiate the [[Mantle]].{{Ref/Book|Id=EncC1|Enc|Section=Chapter One: Timeline, The Foreunners and the Halo Array|Page=26}}{{Ref/Note|This entry, originating from both the [[Halo Encyclopedia (2009 edition)|2009]] and [[Halo Encyclopedia (2011 edition)|2011]] editions of the ''Halo Encyclopedia'', is of dubious accuracy in light of information from ''[[The Forerunner Saga]]'', in which the Forerunners are stated to have been spacefaring for millions of years (albeit having experienced a number of technological dark ages and large-scale record loss events over the course of this period) and that they held the Mantle since for around 10 million years, having forcibly seized it from the [[Precursor]]s. However, the ''Encyclopedia'' notes that ''"all Forerunner era dates are approximate, based on available translation and scattered historical data"'', which provides a canonical explanation for the possible inaccuracies of this entry.}}
*According to Forerunner research, the [[Ancestors]], were believed to have "moved their interstellar civilization outward along the galactic arm" around this time, possibly to escape Forerunner control.{{Ref/Novel|Id=HCC1|Cry|Chapter=1}}
