In my version of the Mass Effect storyline, Commander Anna Shepard chooses to take over for the Reapers. They relinquish their powers to her, in shame and humility. To the galaxy at large, it seems that the Reapers have been destroyed and Shepard has disappeared. Only Liara knows the truth about what has happened, and she is good at keeping secrets!
Meanwhile, the galaxy has entered a new age of exploration. New alliances are forged.
Note:
These are screencaps from NMS that I played around with using GIMP (free art software!) and a Wacom graphics tablet. I’m just getting the hang of GIMP. I know the more I practice, the less awkward it will seem.
