Shepard chose to destroy Sovereign. The Council then declared war on the SA for that betrayal. The Humans tried to fight but it was a losing battle. Subjugation leading to extinction was not acceptable for making the hard military decision so the Humans chose another path and made a deal with the Reapers. The galaxy and the Cycle would never be the same. AU Shepard makes the rules

Harry Potter has been banged up for ten years in the hellhole brig of Azkaban for a crime he didn't commit, and his traitorous brother, the not-really-boy-who-lived, has royally messed things up. After meeting Fate and Death, Harry is given a second chance to squash Voldemort, dodge a thousand years in prison, and snatch everything his hated brother holds dear. H/Hr/LL/DG/GW.
