Before The Council: The Seeds Of Destruction

Long before the rise of humanity or the formation of the Citadel Council, a cosmic drama unfolded, setting the stage for everything that would follow. This era is dominated by the enigmatic Protheans and the terrifying Reapers.

The Protheans were once the dominant civilization in the Milky Way, a vast empire that spanned countless star systems. Highly advanced and seemingly invincible, they believed their reign would last forever. But they were wrong. Every fifty thousand years, an ancient evil awakens from the darkness of deep space: the Reapers. These colossal, sentient machines are dedicated to a chilling purpose: the systematic extermination of all advanced organic life. The Reapers believe this horrific cycle is necessary to prevent the eventual destruction of the galaxy by synthetic/organic conflict.

The Protheans, despite their power, were ultimately overwhelmed. They fought bravely, but the Reapers were too powerful, too relentless. As the Prothean civilization crumbled, they desperately tried to leave behind clues and warnings for future generations, hoping someone, someday, could break the cycle. The Citadel, a massive space station of unknown origin, and the network of Mass Relays, were left behind, strategic tools designed by the Reapers to streamline the galaxy’s periodic harvest. These relics, intended as instruments of destruction, became catalysts for galactic civilization and interaction, an ironic twist that defied the Reapers’ intentions.

Beyond the Prothean-Reaper conflict, other civilizations were slowly emerging, independently developing along their own unique paths. The Asari, with their long lifespans and innate biotic abilities, were evolving on Thessia. The Salarians, known for their intellectual prowess and rapid development, were forming their own societal structures. On Tuchanka, the Krogan were becoming the brutal, warlike race they would later be known as. And on Palaven, the Turians were forging their rigid, disciplined society. These nascent civilizations, unaware of the cosmic forces at play, were unknowingly preparing to inherit a galaxy scarred by an ancient war.

A New Galaxy: Exploration And First Encounters

The discovery of the Charon Relay by humanity in the year twenty-one forty-nine marked a pivotal moment in galactic history. This discovery wasn’t just about finding a new technology; it was about unlocking the door to the wider galaxy. The initial exploration was cautious, tentative, but the implications were immense. Humanity, confined to its own solar system, suddenly had access to interstellar travel on a scale never imagined. This revelation had a profound impact on human society, accelerating technological advancements and igniting a sense of boundless possibility. The galaxy, once a distant dream, was now within reach.

However, humanity’s first contact with another species was anything but peaceful. In twenty-one fifty-seven, a patrol fleet of the Systems Alliance inadvertently attempted to activate a dormant Mass Relay, a prohibited act according to Turian law. This misunderstanding ignited the First Contact War, a brief but intense conflict that demonstrated humanity’s growing military capabilities and the unwavering discipline of the Turian Hierarchy. While short-lived, the war was a stark reminder of the potential dangers of interstellar relations and left a lasting scar on both sides. It also revealed the existence of a larger galactic community, governed by the Citadel Council.

The Citadel Council, comprised primarily of the Asari, Salarians, and Turians, served as the central governing body for much of the galaxy. It was an institution built on established protocols and traditions, where the three founding races held considerable influence. Humanity’s arrival on the galactic stage presented a new dynamic, a potential challenge to the existing power structure. The First Contact War had shown humanity’s military prowess, but also its relative inexperience in galactic politics. The humans faced a challenging path, navigating the complexities of Citadel society and striving for recognition and respect.

Commander Shepard’s Era: The Gathering Storm

The years between twenty-one eighty-three and twenty-one eighty-six are defined by the actions of one individual: Commander Shepard. These are the years of the original Mass Effect trilogy, a time of unprecedented danger and galactic upheaval.

Twenty-one eighty-three marked the beginning of Shepard’s journey. As a Spectre, an agent of the Citadel Council, Shepard quickly uncovered a conspiracy that threatened the entire galaxy. The rogue Spectre Saren Arterius, a Turian war hero, was revealed to be working with the Geth, a synthetic race exiled centuries ago. Shepard’s investigation led to the discovery of ancient Prothean ruins and a chilling revelation: the Reapers were real, and they were coming.

The attack on Eden Prime was a pivotal event. The beacon left behind by the Protheans contained warnings and prophecies. The attack served as a wake-up call for the galaxy, exposing the looming threat and revealing Saren’s treachery. The beacon’s vision showed Shepard the future.

The year twenty-one eighty-five saw Shepard resurrected by Cerberus, a pro-human organization with questionable ethics. Tasked with stopping the Collectors, a mysterious race abducting entire human colonies, Shepard embarked on a perilous mission to assemble a team of specialists and uncover the Collectors’ true purpose. The mission involved recruiting a diverse crew, each with their own skills, stories, and motivations, and undertaking suicide missions to secure their loyalty.

The assault on the Collector base represented a turning point. The horrifying experiments on the humans and the discovery that the Collectors are Protheans served as a wake-up call. Success depended on Shepard’s leadership and the crew’s loyalty, influencing the fate of the mission and the future of the war.

In twenty-one eighty-six, the Reapers finally arrived. The galaxy was plunged into a full-scale war, with Earth being among the first planets to fall under their devastating assault. Shepard, stripped of command but not of resolve, embarked on a desperate mission to unite the galaxy’s disparate races and build the Crucible, a superweapon designed to defeat the Reapers. The journey was fraught with political maneuvering, difficult choices, and heartbreaking sacrifices. The genophage cure for the Krogan, brokering peace between the Quarians and Geth, and overcoming internal divisions within the Citadel Council tested Shepard’s leadership and resolve.

The Crucible’s activation marked the climax of the Reaper War. The battle for Earth raged, as Shepard made their way to the Citadel. The ultimate confrontation with the Reapers demanded a choice, a decision that would determine the fate of the entire galaxy. The consequences of that choice remain debated to this day.

After The War: A Galaxy Reborn

The immediate aftermath of the Reaper War was one of widespread devastation. Entire planets were ravaged, civilizations were shattered, and countless lives were lost. The galaxy faced the monumental task of rebuilding, of piecing together what remained and forging a new future.

The state of the galaxy depended heavily on the choices made at the Crucible. Whether the Reapers were controlled, destroyed, or integrated, the consequences rippled throughout the galaxy, affecting every species and every world. All choices had repercussions.

The long-term future of the Milky Way remains uncertain. The war’s impact on galactic politics, technology, and societal structures will be felt for generations to come. New threats could emerge, new alliances could form, and the galaxy could evolve in ways no one can predict.
