Honestly, the timeline is still wrong in the first place.
There should be a timeline split in Skyward Sword and, logically, some games along a timeline where Demise won and subjugated the world but would still be fell by another reincarnation of Link.
Because when you think about it, Skyward Sword has a definitive timeline split.
Pre-Lifeseed Tree and Post-Lifeseed Tree timelines.
There is a timeline that Link abandoned by accident when he went into the past to plant the Lifeseed tree to save Lanayru from his terminal illness.
And a timeline where the Lifeseed Tree grew in the The Sealed Temple (
the timeline we have followed thus-far).
Because before you go back in time, Groose comments on how the spot for the Lifeseed tree is empty and would be a nice place to plant something like a garden.
Then when you come back, Groose in the post-lifeseed tree timeline will comment about how whenever he gets worried or anxious he goes to the tree to feel calm and ease his nerves.
So...
Now I want to see a Zelda game where Demise got what he wanted... somewhat.
He broke free of his imprisonment and consumed Zelda, still sealed in Amber, to regain his true form.
With his newfound might, he ravages the world and builds an accursed tower to reach to the sky and invade skyloft, causing the floating islands to plummet to the ground below.
And yet, he cannot find the Triforce.
So instead, he subjugates the races with his demon hoards.
Until Link is reincarnated once again and we have a game where we are fighting an intensely uphill struggle with a faction of rebels trying to change the balance of power.
Link discovers the Triforce and has to use it to finish what his past incarnation accidentally failed to do - destroy Demise!
EDIT -
I made an excel spreadsheet to show what this "canon" timeline SHOULD look like, based off of the timeline presented in The Legend of Zelda: Encyclopedia by Dark Horse Comics.
