Kotaku - Sources: Mass Effect: Andromeda Will Not Get Single-Player DLC

Well I mean the fan fic was not me fixing the ending, just the ending, but really my reaction to wanting to fix ME 3 as a whole because its a game I saw a lot of problems in the game as a whole, and a lot of things I wanted to fix...so in that sense it was very fan ficky.  

Basically though Abigail Shepard manages to convince the Catalyst the Reapers are not needed and that the solution is not necessary. He then takes the fleet and flies them into the sun.  She is very gravely injured so has to go through rehabilitation. Then at the end, starts being a part of the rebuilding effort to rebuild the Galaxy in the wake of the Reaper war. Then Abigail discovers a group of people, the Disciples of the Reapers, who start worshiping them as dieties. They want to bring the cycle back because they view the cycle as necessary.  At the end of the day she discovers that the core of Harbinger, his essence, rejected the Catalyst and is the one leading the Disciples of the Reapers, which then sets up a final battle between him and the forces of the Galaxy.  Sacrificing are made, blasts from the past are resurrected, and Shepard is temporarily indoctrinated.
