User blog:James12708/Possible real origin of the reapers?

I'm on board with thinking the mass Effect 3 ending is a dream. I have a possible theory on the actual orgin of the reapers. Billions of years ago a species ( without the mass relays ) was able to colonize the milky way. They allied and conquered other species eventually forming a galactic alliance. After years of peace this alliance of species decided to finally leave the milky way. They had ended up finding several other galaxies who had reached their level of advancement. There was peace for a few thousand years until a religous cult began to take shape that taught that the gods wanted to massacre or convert everyone to there religion ( think covenant from halo ). Eventually many species in the milky way accepted this cult and the ones that didn't were enslaved or exterminated. After coming to control the Milky Way alliance the species from the milky way prepared for war in the name of their gods. They had an army in the hundreds of trillions and many weapons of mass destruction. Then they launched a total war on the other galaxies. They massacred and tortured the severly outnumbered rival galactic empires. After whole galaxies were stripped bare and left with nothing but dust and corpses the other galaxies all joined together to end the war. In total they amassed an army that was numbered in the quadrillions ( bigger than trillions ). This began a brutal war that lasted for nearly 500 years and seemed to be never ending. The Milky Way alliance though heavily outnumbered was much tougher. Then the other galaxies began the construction of a weapon that was so large it could destroy a whole galaxy. Since many soldiers had been captured and where being held in the milky way the other galaxies came up with a plan. They lured 90% of the milky way alliance into battle against a small number of their fleets in dark space. Since they had been tricked into sending almost there entire fleet the Milky Way alliance was annihalated when the weapon was detonated. A few years later the war was over. As a permanent punishment for their genocide the other galaxies built the mass relays and several reapers to ensure no species from the milky way would ever get advanced enough to leave their galaxy.. This cycle continued ever since then.
