It's been thirty years since Thanos, since the endgame battle between his forces and the Avengers. Earth slowly recovered and returned to normal, happily rebuilding itself since people came back because of the Blip. Now the majority of the Avengers have retired, but the mantles have been filled by their children, now full-grown adults. When a portal sends a few of the Avengers to another universe, things are going to get hectic, as they try to get used to their new surroundings. The world of Mass Effect will never be the same again.
