Time Between Mass Effect 2 And 3

watch 04:57

The Entire History of the Mass Result Universe

This is the timeline of the Mass Upshot universe. All dates are in BCE (Before Common Era) and CE (Common Era).

Note: Numerous events are backdated during conversation, via Codex entries, or some other ways from the fourth dimension the stories are prepare: 2183 to 2186 CE for the Shepard trilogy, 2819 CE for Mass Effect: Andromeda, and the like. These aren't frequently given exact dates. Unless an exact engagement is given for an event, the following outlines how to handle approximate dates.

Huge timescales should not be taken literally; "nearly a billion years ago" from Mass Effect does not exactly mean "this outcome happened in 999,997,817‬ BCE". Aforementioned goes for millennia up to 4 meaning digits: "300,000 years ago" from Mass Outcome 2 (set 2185 CE) is approximately 298,000 BCE. "15,000 years" of turian civilization equates to virtually thirteen,000 BCE, and so forth.

Decades or centuries earlier/afterward the "present twenty-four hour period" tin can be dated to the nearest units or tens, depending on source context.

Prehistoric Times (Unknown BCE - c. 1,000,000,000 BCE)

Unknown BCE

A rock painting of a Leviathan

The Leviathans dominate the Milky Way, enthralling every new sapient race they encounter and protecting them in render for tribute. The Leviathans consider themselves the galaxy's kickoff and only apex race.

After observing that their subservient races create synthetic races who consistently and violently rebel, the Leviathans create an Intelligence to seek a mode to permanently preserve organic life. The Intelligence constructs an army of "pawns" to assemble genetic data throughout the galaxy.

The Intelligence betrays the Leviathans, using its pawns to slaughter them for their genetic material to create Straw, the first Reaper. Thus begins the cyclical harvest of the galaxy's intelligent organic life by the Reapers, part of a vast experiment conducted past the Intelligence to fulfill its mandate.

The Intelligence builds the mass relay network to increase the efficiency of the cycles, allowing galactic civilizations to develop faster and more than consistently between harvests.

Pre-Prothean Times (c. ane,000,000,000 BCE - c. 68,000 BCE)

c. ane,000,000,000 BCE

The Leviathan of Dis, a Reaper, is killed by the Leviathans. Its corpse comes to rest on the planet Jartar and remains undisturbed for about i billion years.

c. 37,000,000 BCE

An unknown spacefaring race fires a mass accelerator round at a Reaper nigh the planet Mnemosyne. The circular penetrates the Reaper, disabling information technology, and continues moving through space, somewhen striking the planet Klendagon and creating the geological characteristic there known as the Great Rift Valley.

c. 298,000 BCE

The aboriginal arthenn race flourish in the Zelene system, living on the planet Helyme until being destroyed in an unknown issue that wiped out all complex life on the planet. They also maintained a presence on other planets in the organization including Epho, which bears the scars of an aboriginal orbital battery, and Gaelon, which may accept been mined for helium-3.

c. 125,000 BCE

Ancient spacefaring races chosen the thoi'han and inusannon fight over the planet Eingana, littering the planet with the debris of hundreds of starships. Refined element cypher scattered past cleaved drive cores contaminates the environs, causing many native species to go extinct and those that survive to show a tendency to develop biotic powers.

Pre-Council Times (c. 68,000 BCE - 500 BCE)

c. 68,000 BCE

The Protheans achieve spaceflight and discover mass result applied science from the ruins of the extinct inusannon. They continue to establish a galaxy-wide civilisation linked by the mass relay network with the Citadel as their capital.

At some point, the Protheans encounter a hostile race of machine intelligences that endanger their existence. To combat this threat, the Protheans aggressively assimilate many other spacefaring organic races into their empire. The Prothean Empire is able to fend off the machines in a disharmonize known as the "Metacon War".

c. 48,000 BCE: Fall of the Protheans

The Prothean Empire collapses with the arrival of the Reapers through the Citadel. Although the Protheans had learned of the Reapers' existence from studying the ruins of previous civilizations and had begun to set up, they were nonetheless caught off-guard. Over the side by side several centuries, the Protheans fight the Reapers system by system, world by world, and metropolis by urban center. In the terminate, it is not enough. The Reapers methodically wipe out the remaining Protheans, every bit well as other contemporary races, and depart the milky way to look the adjacent bicycle.

The Citadel Quango makes showtime contact with the turians around this time and persuades them to help in the war. Afterwards the krogan answer to the initial turian offensive by devastating turian colonies with weapons of mass destruction, the turians vow to stop the krogan from ever condign a threat over again.

Sometime afterwards the turians join the galactic customs, the volus are accepted every bit a customer race of the Turian Bureaucracy.

The geth revolt against their quarian masters. In the resulting disharmonize--known to the geth as the Morn War--the geth systematically bulldoze the quarians from their own worlds. The surviving quarians are reduced to living every bit spacefaring nomads aboard the Migrant Fleet. Reverse to expectations, the geth practise not venture exterior the erstwhile quarian systems into wider Citadel infinite, instead isolating themselves from the rest of the galaxy behind the Perseus Veil. Every bit penalty for creating the geth, the Citadel Quango closes the quarian diplomatic mission on the Citadel.

The remaining eleven billion drell on Rakhana gradually perish, warring over the last reserves of food and water.

Aria T'Loak assumes control of Omega after defeating the space station's previous warlord in single combat. She mockingly bestows the title "Patriarch" on the broken krogan, and uses him equally a reminder to her enemies of her power.
