This began with the creation of the Mass Relay an FTL system put into place throughout space whereupon the Reapers departed into dark space, the extragalactic void just outside the galaxy where the machines slumbered until life began to flourish in the galaxy. At some point in the distant past, they embarked on a project that would create a self repetitive cycle through which they could function across the millennia. In time, this machine race became mythical beings and were attributed the name Reaper by those races that suffered from their harvests. As a result, the only option was to purge organics and upload their conquered minds into new Reapers.

Thus, a cycle of destruction was created as the Intelligence believed that nothing could stop eventual warfare between organics and synthetics. During its study, the Intelligence turned on its makers and slaughtered many of their number who were converted into the first Reaper known as Harbinger. In an effort to find a solution, the Leviathans constructed their own 'Intelligence' tasked with finding a solution to the problem of organics and synthetics destroying one another. Through their natural power, they were able to enslave other species to their will but many of their subject races died following the development of artificial intelligences. The Leviathans had the races under their thrall and were the dominant species of their era. Their origins were actually traced to an even older species known as the Leviathans. The Reapers were an ancient race of machine intelligences that were constructed billions of years ago in the Milky Way Galaxy.
