The hero that "died" saving the White Whale, Elma's tandem Skell partner that you see at the beginning of the game and that she talks about in her final affinity mission in the base game, didn't actually die but got trapped in I Can't Believe It's Not the Collective Unconscious where he saw glimpses of the Xeno multiverse, including scenes from Xenoblade 1-2-3. So Xenoblade X is confirmed as part of the same multiverse, even if it takes place in another dimension from the mainline games (well, actually 3-5 other dimensions, but that's another can of worms)
