Humans (Mass Effect)

Humans are from the planet Earth in the Mass Effect Universe.

Human space exploration began in earnest in the late 21st century but they had not discovered FTL. In 2148, human explorers on Mars uncovered a long-ruined Prothean observation post. A global rush began to decipher the petabytes of data from the outpost. Discovering information on a mass relay orbiting Pluto, explorers managed to open it and discovered it led to Arcturus. With this discovery of Mass Effect Physics, humans expanded to other systems, opening any mass relays they could find. Thereafter they colonized worlds and made contact with many alien species.

In 2186, the Reapers invaded the galaxy. The nature of the threat remained unknown until the Reapers arrive at Earth. Their assault rapidly overwhelms the Earth's defences and they had to retreat. In the ensuing Reaper War, the majority of human worlds remain under Reaper control as they begin their harvest. Millions of humans perish.
