Timeline

From Mass Effect Wiki

Jump to: navigation, search

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



Contents

48000 BCE (Approximate)

The Protheans, a galaxy-wide civilization linked by the mass relay network, mysteriously vanish, leaving only ruins behind. Much of the technology in use by younger species, such as humans, is eventually based on their artifacts. Archaeologists believe that they were destroyed in a cataclysm.

1900 BCE (Approximate)

Tuchanka, the krogan homeworld, enters the nuclear age. In a global conflict, weapons of mass destruction are released, triggering a nuclear winter. In the resulting devastation, krogan society devolves into a collection of warring clans.

1800 BCE (Approximate)

A supernova propels one of the mass relays out of its position. The dense nebula formed by the supernova means the relay's position is effectively lost.

580 BCE

After developing faster-than-light spacefaring capabilities based upon Prothean technology, the asari begin to explore the mass relay network, and eventually discover the huge Citadel space station at a hub of many mass relays.

520 BCE

The salarians discover the Citadel and open diplomatic relations with the asari.

500 BCE

The Citadel Council is formed. The asari and salarians together colonize the Citadel station and establish it as a center of the galactic community, led by the Council. With the participation of the volus, a single galactic currency is eventually established, linking all galactic economies.

This year is also known as 0 GS, the beginning of the Galactic Standard (GS) timeline.

500 BCE - 0 CE (Approximate)

The turian Unification War begins.

The Council races begin expanding the galactic community, opening first contact with other spacefaring races and integrating them into the Citadel. This is a period of rapid growth and occasional conflict.

0 CE

The Rachni Wars

The Citadel Council first encounters the rachni, a species of highly intelligent hive-minded insects. They are discovered when an expedition opens a dormant mass relay to their star systems. The rachni prove to be hostile and begin a war with the rest of the galaxy. The Council cannot negotiate because they cannot contact the rachni queens that live underground on the toxic rachni home worlds.

80 - 300 CE (Approximate)

The Rachni Wars continue. The salarians transplant the primitive krogan to another world and manipulate them into acting as soldiers for the Citadel Council. Able to survive the harsh environments of the rachni worlds and kill the queens, the krogan hunt the rachni to extinction.

300 CE

In gratitude for their aid during the Rachni Wars, the Council grants the krogan a new homeworld. Free of the harsh environment of Tuchanka, the krogan population explodes.

300-600 CE (Approximate)

The krogan begin to expand exponentially, colonizing many new worlds. Growing concerns about their expansion lead to the founding of the Special Tactics and Reconnaissance branch of the Citadel.

700 CE

The Krogan Rebellions

Krogan warlords leverage veterans of the Rachni Wars to annex territory from others in Citadel space. Eventually the Council demands withdrawal from the asari colony of Lusia, but the krogans refuse. A pre-emptive strike is made on krogan infrastructures by the Council, using the newly-created Spectres. The Krogan Rebellions begin.

First contact is made with the turians. In response to krogan threats, they declare war. After the krogan devastate turian colonies with weapons of mass destruction, the turians respond with a salarian-engineered bioweapon, known as the genophage. The krogan population starts its decline.

800 CE

The Krogan Rebellions end. The turians begin to fill the military and peacekeeping niche left by the decimated krogan.

900 CE

The turians are granted a place on the Citadel Council, and their fleet acts as a galactic peacekeeping force.

1900 CE (Approximate)

The Geth War

The quarians create the geth. The quarians notice geth showing signs of independent thinking, and plan to destroy them before they have chance to become self aware. The geth rebel against their quarian masters and, in the resulting war, reduce the quarians to a species of space faring nomads aboard the Migrant Fleet. Contrary to expectations, the geth do not venture outside the former quarian star systems, instead isolating themselves from the rest of the galaxy behind the Perseus Veil.

1900 CE-2100 CE

The galactic community continues to expand. With the exception of the Geth War, this period is a time of peace and prosperity.

2069 CE

Armstrong Outpost at Shackleton Crater becomes the first human settlement on Luna. It is formally founded on July 24, the 100th anniversary of the first lunar landing.

2077 CE

Liara T'Soni is born to Matriarch Benezia and an unknown asari.

2103 CE

Lowell City in Eos Chasma becomes the first permanent human settlement on Mars.

2137 CE

David Anderson is born.

Ashland Energy Corporation demonstrates helium-3 fuel extraction from the atmosphere of Saturn.

2139 CE

Saren Arterius is born.

2142 CE

Construction of Gagarin Station (Jump Zero) begins beyond the orbit of Pluto.

2148 CE

Humanity discovers a small cache of highly advanced Prothean technology hidden deep beneath the surface of Mars on the south polar region of Promethei Planum. Building on the remnants of this long extinct race, humans quickly explore the science of mass effect fields, leading to the development of faster than light travel and beginning detailed exploration of the solar system.

2149 CE

Following information from the translated data cache on Mars, humans discover that Charon, Pluto's moon, is actually a massive piece of dormant Prothean technology - a mass relay - encased in ice.

Once activated, Jon Grissom leads the first team of explorers through the relay. They discover that the Charon Relay allows instantaneous travel across thousands of light-years to a synchronized mass relay in another part of the galaxy.

The Systems Alliance charter is signed by the eighteen largest nations on Earth. The Alliance soon becomes the military and exploratory spearhead of humanity.

2151 CE

To defend its rapidly expanding empire, humanity assembles a massive fleet and begins construction of an enormous military space station at Arcturus, at the nexus of several key mass relays... even though they have yet to encounter another intelligent space-faring species.

An accident at Singapore International Spaceport exposes a human population to dust-form element zero.

Kaidan Alenko is born.

2152 CE

The Systems Alliance begins settlement of Earth's first extra-solar colony world, the planet Demeter.

Roughly 30% of the children born in Singapore after element zero exposure suffer from cancerous growths.

2154 CE

Commander Shepard is born.

2155 CE

Saren Arterius is promoted to active service in the turian military at 16.

The Systems Alliance occupies completed portions of Arcturus Station as a headquarters.

2157 CE

The First Contact War

Humanity makes first contact with another space-faring culture: the turians. Unfortunately, the encounter is far from peaceful. The turians find the human fleet attempting to activate a mass relay, something forbidden in galactic law after the Rachni Wars, and attack. Over the next several months, a brief but tense conflict known on Earth as the First Contact War ensues. David Anderson, newly graduated from the Alliance's elite N7 programme, serves with distinction alongside Jill Dah. Saren's brother is one of the turian casualties. Finally General Williams is forced to surrender the garrison at Shanxi to the turians, which is later liberated by the Alliance fleet.

This conflict draws the attention of the Citadel Council. The Council intervenes before hostilities escalate further, revealing the existence of the greater galactic community to humanity and brokering a peace between them and the turians.

2158 CE

Ashley Williams is born.

Humans learn potential of biotics. An international effort to track element zero exposures begin. Roughly 10% of exposed children show some sign of biotic ability.

2165 CE

Humanity continues to expand, founding more colonies and establishing trade alliances with many of the other species who recognize the authority of the Citadel Council. In 2165, the Council makes official recognition of humanity's growing power and influence in the galactic community. Humanity is granted an embassy on the Citadel, the political and economic heart of the galaxy. Tensions grow between humans and batarians as they compete for territory in the Skyllian Verge.

The events of Mass Effect: Revelation occur. Saren uses files taken from Dr. Shu Qian and Edan Had'dah to start searching for the artifact discovered near the Perseus Veil.

2167 CE

L2 biotic implants first developed and used in humans; Kaidan Alenko is among the first to receive the new implants.

2170 CE

The human colony of Mindoir is attacked by batarian slavers. Many colonists are killed or captured.

L3 biotic implants are developed after the L2 implants prove to be dangerous.

2171 CE

In protest at the Council's refusal to check human expansion in the Skyllian Verge, the batarians close their embassy, withdraw into their home systems, and effectively become a rogue state.

2174 CE

After taking heavy losses the batarians withdraw from Citadel space into their home systems.

Tali'Zorah nar Rayya’s mother dies after contracting an airborne virus aboard the Flotilla.

2183 CE

Humans and turians collaborate on an engineering project co-founded by the Citadel Council - an experimental frigate with a prototype stealth system, the SSV Normandy. The Normandy is commissioned with Captain Anderson in command. Commander Shepard - now a promising young officer in the Alliance Navy - is assigned as XO.

The events of Mass Effect occur.
