When was citadel constructed mass effect

Thanks to Commander Shepard and the discovery of a Prothean beacon on Eden Prime, it was determined that the Protheans had been wiped out by the Reapers and their indoctrinated servants. They were not technically extinct, however. The Reapers had captured millions of Protheans and genetically-engineered them to become the Collectors. Beside those husks, one last Prothean remained, kept alive by an active Prothean VI. Javik was one of the paragons of the Prothean empire and was awakened by Shepard 50, years after the annihilation of his people.

He was the last and almost immediately continued the fight against the Reapers. The extreme climates of the Rachni homeworld of Suen forced the Rachni to survive underground, where they were discovered by Prothean explorers. The Protheans bred Rachni to be weapons of war, though they eventually lost control. Though the Rachni were beaten back by Prothean forces, Suen was never conquered, allowing the insectoid race to survive and grow again, this time becoming a space-faring species.

They came into contact with the Citadel Council when Salarian explorers encountered them and accidentally provided them with faster-than-light technology, leading to the Rachni Wars. These aliens were believed to have been extinct for several hundred years, after the Krogan helped to wipe them out. It preserves them, but only in the sense that it turns them into jam. The Catalyst begins with its own creators, transforming them into the first reapers and beginning the war its creators had tried to avoid.

A reaper called the Leviathan of Dis is defeated by the actual leviathans. In the long term, however, the leviathans fail. The reapers begin their cycle of accelerating cultural advancement by leaving mass effect technology lying around the galaxy for rising species to find, then absorbing those species once they become advanced enough. The protheans are the last in a long line of species to fall to the reapers. Though the protheans had learned of the reapers and begun to prepare for their arrival, they were too late.

Their preparations survive into the next cycle, however, in the form of the Crucible. Nuclear conflict devastates the krogan homeworld of Tuchanka, and the advanced society of the krogan devolves into one of warring clans in a post-apocalyptic wasteland. The asari, the first post-prothean race to encounter the mass effect relays and develop faster-than-light travel, discover Citadel Station.

The Citadel Council is formed after the asari are joined on Citadel Station by salarians, the two species working together to find and unite other civilizations. Contact is made with quarians, volus, hanar, and batarians. One of the Citadel Council's interplanetary expeditions encounters the rachni after opening a relay leading to systems controlled by their hive mind.

The Rachni Wars begin. The rachni are declared extinct after being defeated by the krogan, who have been genetically uplifted by salarians specifically to combat them.

As a reward for their efforts the fast-breeding krogan are given rachni worlds and several planets in Citadel space to settle. Beelo Gurji, a salarian agent working for the Citadel Council, is accused of using civilians as bait during an espionage operation. Rather than being punished Gurji is promoted, becoming the first Spectre.

As the squad escapes the planet, they witness a fleet of Reapers descending on the planet to finish its destruction. The squad arrives at a facility, where they discover that Cerberus was experimenting on humans, influencing them with Reaper technology to try and control the Reapers.

Though they don't find the Illusive Man, they find the Prothean virtual intelligence, who reveals that the final piece in the Crucible design is actually the Citadel itself, but it's too late as the Reapers took the Citadel and transported it to orbit Earth. They suffer heavy casualties, both in orbit during a massive space battle, and on the ground, with many or none, somehow of Shepard's crew members getting severely injured or killed. After making their way to the Citadel, Shepard and Anderson are confronted by the Illusive Man, now looking like a weird cyborg-like creature irrefutable proof that he's been indoctrinated by the Reapers.

Whether by Shepard's hand, or his own, the Illusive Man is killed, Shepard activates the Crucible as Anderson dies from his injuries. After briefly passing out from blood loss, Shepard wakes up in front of a synthetic entity manifesting itself in the form of the boy Shepard saw die as he fled Earth at the beginning of the game.

The entity is the Catalyst itself, who explains the first portion of this timeline, how it created the Reapers, what their purpose is, and so on. Shepard can either destroy the Reapers and all synthetic life in the galaxy as well as most technology , control the Reapers and become a new Catalyst, or fuse organic and synthetic life, which would perfect organic life by integrating it with technology, and make synthetics fully understand organic life — bringing an end to the cycle and the need for the Reapers.

Even though you technically have a choice — albeit one with a clear very poor option and one that's objectively the right one — Shepard forever changes the course of the galaxy, activates the Crucible or not!

Shepard can also walk away and let everyone die which shoots a beam of colored light, and ends the cycle in one way or another. Surviving crew members mourn Shepard, and many years into the future, a person known as Stargazer tells the story of "The Shepard" to a young boy. In the future, a woman of an unknown race tells the story of "The Shepard" to a young boy, and vows to defeat the Reapers once and for all.

Shepard restores the mass relays, and vows to watch over the squad. Depending on the outcome of the genophage mission, Shepard may be more protective of the weak, or will ensure that "the strongest are not feared or reviled for their strength. The Reapers stopped attacking and even began to help rebuild, sharing the knowledge of all the civilizations they previously harvested.

With the synthesis of all life, EDI speculates that mortality itself could one day disappear, possibly with a better version of an Instrumentality Project that doesn't turn everyone into orange Tang. It attacks all Remnant technology it touches and deactivates most of it. The Angaran civilization falls into a dark age and the golden worlds where the Milky Way space arks are heading to, decline. Five of their worlds rediscover spaceflight and reunite, discovering the differences in their cultures.

Though the Kett appear peaceful, they begin invading Angaran worlds in order to kidnap Angaran leaders. One of the Kett leaders becomes obsessed with Remnant technology. You play as Ryder, son of the human Pathfinder tasked with finding a world fit to be colonized. The Scourge sends Ryder's sibling into a coma, and soon after Pathfinder Alec Ryder learns that the planet they were assigned to scout is no longer viable.

When Ryder, Alec and two companions head to the planet to investigate, they are attacked by the Keth. After finding and activating a Remnant beacon to try and stabilize the planet's environment, a large blast causes Alec to sacrifice himself in order to save Ryder, who is later revived by merging him with an AI known as SAM. They learn that all the worlds in Andromeda have become inhospitable in the time since they departed the Milky Way.

The resulting chaos led to civil unrest and a rise in crime and piracy among the Nexus citizens. Ryder then is tasked with finding a new world with the help of a growing crew of misfits and a shiny new ship.

In the first system they visit, Ryder manages to activate a Remnant vault with the help of the AI implanted in them, and finds a terraforming system that repairs the planet's ecosystem.

This becomes the first successful outpost for the Andromeda Initiative. After aiding the Angara, Ryder recruits Jaal Ama Darav to the crew, and discovers that the Kett have been kidnapping Angara in order to genetically modify them into becoming Kett.

At the same time, the Angara tells Ryder that the Kett leader, Archon, is chasing an object that can control all Remnant vaults, and with them the worlds they are connected to. Afterwards, Ryder gets word that the Kett have captured the Salarian ark and are experimenting with some of the Andromeda Initiative species on board, after freeing the ark, Ryder learns the location of the ancient Remnant device.

Ryder then activates and takes command of the Remnant fleet in order to make an assault on the Kett, and together with Ryder's now-awakened sibling, they kill the Kett leader and stabilize the Remnant devices and the core worlds' environments. Ryder is hailed as a hero, while in a distant spaceship, the Kett's second in command prepares for a future conflict.

Only the mass relays allow ships to jump hundreds of light years in an instant, the key to expanding across an otherwise impassable galaxy.

Whenever a new relay is activated, the destination system is rapidly developed. From that hub, FTL drive is used to expand to nearby star clusters. The result is a number of densely-developed clusters thinly spread across the vast expanse of space, connected by the mass relay network. They are elite military operatives, granted the authority to deal with threats to peace and stability in whatever way they deem necessary. They operate independently or in groups of two or three.

Some are empathetic peacekeepers, resolving disputes through diplomacy. Others are cold-blooded assassins, ruthlessly dispatching problem individuals. All get the job done, one way or another, often operating outside of the bounds of galactic law.

The Spectres were founded after the salarians joined the Council. For many years, they operated in secrecy, as back-room 'problem solvers.

Assignment of a Spectre is less contentious than military deployment, but makes it clear that the Council is concerned about a situation. Mass Effect Wiki Guide.
