“In the end, what does it matter? Your survival depends on stopping them not in understanding them. Our worlds were stripped bare, harvested by the indoctrinated slaves. All technology, all things of value. Everything was taken. The Reapers retreated into Dark Space, taking everything, sealing the Mass Relay behind them. But the indoctrinated stayed behind; mindless husks, no longer capable of independent thought, the indoctrinated soon starved or died of exposure. The genocide of the Protheans was complete; and so the Reapers slept. Now, Saren threatens that sleep, and 50,000 years of progress that was made between our genocide, and this moment.”
