When the Reapers leave the Milky Way, they also leave behind a vanguard that observes the development of organics across the galaxy and reactivates the Citadel to signal the rest of the Reaper fleet to return when the time is right. Once they have harvested all they need, the Reapers retreat once again to dark space and enter hibernation, awakening only when they recieve a recall signal from the Citadel: an enormous space station and mass relay created by the Reapers for the most advanced of organic cultures to find and use to establish galactic society. All underdeveloped races are left alone and allowed to prosper until the next cycle while advanced cultures are harvested, the essence of all they were immortalised in Reaper form. The Reapers' purpose is to allow organic societies to advance to a specific point, then harvest them before they create any artificial life that may threaten to destroy all organic life in the galaxy.

This monstrosity would become known in modern times as ' Harbinger', the first of the Reapers.įor countless millenia, organic races have advanced to the point where they have created synthetic life, only for their creations to rebel against them. This machine was built in the image of the race that conceived it, and would create another in its likeness with every organic species it harvested. And thus, the Leviathans were attacked and slaughtered by their own synthetic creations, their biological essence harvested to produce a new machine that existed to fulfill the Intelligence's mandate of preserving life. The Intelligence deemed that order could only be brought to chaos by harvesting all organic life, including that of its creators. Unfortunately, the Leviathans failed to realise that they had fallen into the same trap that their thralls had, by creating artificial life to solve a problem that organics could not solve alone. Seeing the struggle between organics and synthetics as a problem to be solved, the Leviathans created an ' Intelligence' that would find a means of preserving life at all costs. However, a time came when the Leviathans' servant races created synthetic life to aid them with their various tasks, only to have their creations rebel. In the Leviathan add-on content, it is revealed that the Reapers were originally conceived by a powerful race of aquatic-based creatures referred to as ' Leviathans', who were once a dominant 'apex' race that controlled all other races in the galaxy. Mostly used on fish, once a few drift into’s it’s mouth it bites down and eats it’s meal.Before the events of Mass Effect 3, absolutely nothing was known about the origins of the Reapers. Usually during night, it’s mouth has the same look as a small cave due to the kelp that hangs from it’s teeth. The webbed ends help increase it’s speed, this method allows the sand leviathan to stun its prey out of fear or attack them quickly before they escape.Īn alternative attack which is more focused on stealth, the creature hangs it’s mouth open out of the sand. When attacking, depending on the size and length between itself and it’s prey, it uses it’s front legs to launch it’s self out of the sand. The sand leviathan is not usually hostile towards humans, and only attacks if provoked. Though fish seem to be attracted to it still. When night time however they horns are covered by their glowing back and can be spotted by people. They also bury themselves into the sand only allowing their corral like horns to stick out of the sand.
