History of the Mass Effect Universe
The Mass Effect universe is a rich tapestry woven from millennia of galactic history, marked by the rise and fall of civilizations, the discovery of Mass Relays, and the ever-present threat of the Reapers. From the ancient Protheans to the modern galactic community, understanding this history is key to grasping the stakes of Commander Shepard's fight.
The discovery of Mass Relays by the Protheans, an advanced ancient race, revolutionized interstellar travel, connecting vast swathes of the galaxy. Their civilization was ultimately wiped out by the Reapers, a synthetic-organic race of starships that periodically harvest advanced organic life. The Protheans left behind ruins and artifacts, including the Shadow Broker archives and the Prothean Beacon on Eden Prime, which played a crucial role in humanity's early space exploration and Shepard's initial encounter with the Reapers.
Following the Prothean extinction, other races rose to prominence. The Asari, the first species to discover the Mass Relays, established the Citadel Council, a governing body that has maintained a fragile peace for centuries. Other major races include the Turians, a militaristic society; the Salarians, a technologically advanced and rapidly reproducing species; the Krogans, a hardy warrior race; and the Quarians, a nomadic people forced from their homeworld. Humanity, a relatively young species, joined the galactic stage centuries later, quickly proving its mettle and eventually earning a seat on the Council.
The events of the first two Mass Effect games laid the groundwork for the galaxy-wide conflict in Mass Effect 3. Shepard's actions, from stopping Saren and the Geth to dismantling the Collectors, have had far-reaching consequences. The galaxy is now on the brink of war, with the Reapers having finally arrived in full force, threatening to extinguish all advanced organic life. The history of the Mass Effect universe is not just background lore; it's a living narrative that directly impacts the choices Shepard makes and the fate of all sentient beings.
