User blog comment:Legionwrex/What do Reapers do with the technology they harvest?/@comment-5379655-20130106030711

I actually don't think they do anything with the technology. I'm pretty sure you are mistaken on that point unless you can quote where you found it. I say this because there are countless worlds where enormous prothean megacities cover entire continents. I'm pretty sure those would have been noticed by the Reapers if what you're saying is true. Most likely, everything just wears away. 50,000 years is a long time for the elements to wipe away all traces of a civilization.
