User blog comment:LDR/Possible Reaper Motive/@comment-1824113-20120224040222

Maybe the Reapers were great war machines or something that were created by the merging together of thousands of people to create something that could conquer the Galaxy. But then something happened which caused the Reapers to decide to destroy and subsume EVERYONE into one of their constructs. I'm kind of reminded of the series Fullmetal Alchemist, where the Philosopher's Stone was created as a weapon or a device by collective merging of hundreds or thousands of peoples souls. A creation bourne of Pride. A frankenstein.
