Saving the Quarians & the Geth
Commander Shepard is faced with an extremely difficult decision: either let the Geth upload the Reaper Code, granting them true AI but allowing them to destroy the Quarians; Or saving the Quarian Fleet by preventing the upload but allowing them to continue their assault, which would destroy the Geth. Instead, he opts to convince the Quarian Fleet to stand down while also allowing Legion to upload the code, thus enabling peace.
