Things from Totk's Masterworks
- The Ancient Zonai's birth may have to be after Hylia gave up her goddess form in Skyward Sword and gift them the Secret Stones through her goddess statues. We know Hylia is active enough in the Wild Era to move the horned statue from Hateno Village but sense we only know the statues were used to trade blessings for spirit orbs it's understandable why some take issue with this. We also would have to assume a reason for Hylia to give the Stones to the Zonai which otherwise can be interpreted to be before she gave up her goddess form to reincarnate as a mortal.
- A diagram of how the purification unit works shows that no malice escaped the seal until the castle was damaged by Calamity Ganon and Rauru's body deteriorated over the 100 years prior to Botw. It would have to be assumed the seal would eventually fail to stop all the malice (to be fair in the Zelda series seals never last forever, though OoT and FSA had Link tricked into unsealing something).
Things from Ocarina of Time that have to be remembered/forgotten:
The name Ganondorf cannot be remembered as the name of the evil man that the Zora Monuments describe (unless Ganondorf is the only name for a Gerudo male) while the general events of it are remembered including Ruto and Narbooru awakening as sages. I heard the argument a past Kingdom falling could have been remembered and just not mentioned because it wasn't relevant to the matter at hand but it feels like too much of a stretch and would choose for most of the past Kingdom to be forgotten. Though something like the relevancy explanation is required for Queen Qia to be not mentioned in the present of the Wild Era while Ruto is remembered unless she was forgotten with the seal on Ganondorf for some reason.
A voice memory says faith in Din dimmed due to power being associated with the Demon King which seems like it should be referring to the Ganondorf that uses Din's piece of the Triforce.
Another voice memory says that boars were associated with evil because the Demon King once took the form of a boar which Tearsdorf never transformed in the past, though Daruk did call Calamity Ganon "swirling swine" so it may just refer to that.
Calamity Ganon did turn into Dark Beast Ganon because he was "refusing to give up on reincarnating" which seems to refer to him creating a body but we don't know if Calamity Ganon tried to do that in the past. One piece of evidence that Dark Beast Ganon appeared before Botw is the Voice memory about how Hebra Peak got a hole in it and how it came from Hyrule Castle which either means the Divine Beasts previously fought in Central Hyrule or Dark Beast Ganon shot his laser at Hebra Peak.
The giant fossil in the bottomless swamp was apparently worshipped by Cultists who "considered it the Demon King from Ancient Times" though the voice memory only 100% confirms its a fossil. No skull of Dark Beast Ganon would have existed based off the games we played but it could be interpreted to be from a previous attempt of Calamity Ganon to build a body.
Things based off the timeline placement of the Wild Era
- If its after Wind Waker
- You have to assume the Mastersword wasn't included in Daphnes's Triforce wish to destroy Hyrule even though the weapon was located in it. Some say the Master Sword just healed itself as shown in the Wild Era games when bathed in sacred energy while others think the goddesses rescued the weapon before it was destroyed.
- Someone of Hylia's blood returning to the mountain tops of old Hyrule for some reason (if New Hyrule also falls its even less believable for me for anything to be remembered from old Hyrule).Spirit Tracks does show some thing were remembered but the story of Ocarina being remembered to have included Nabooru is too much for some. to find the Koroks connected the islands together
- The Depths seem to be based off Yomi which in Shintoism is the bottom layer of the world which is decided into three layers and seems to share a geographical continuation with the mortal world. I find it unlikely to have not existed since the creation story.
- Stories of Narbooru and Ruto may not be known in the present of Wind Waker unless Zelda got memories of the story with the knowlege she is a Princess. It's also possible the teacher on Windfall Island, who is theorized to be descended from a Sheikah, may have a book about it but I don't think there's anything confirming it.
- Some interpret Ganandorf to have been sealed in Wind Waker while others think he was killed but either way it felt like an ending for Ganondorf as a character in that timeline (Twilight Princess also has this but him being buried under an entire ocean makes if more permanent to me, especiallly because it was caused by a Triforce Wish.
- If you think Chancellor Cole or Malladus are reincarnations of Demise's hatred then the curse would go back to a Ganondorf for some reason.
- If its in the Downfall timeline
- The law about every Princess Zelda would have to be forgotten as Botw says it is a tradition.
- That Zelda the first from AoL would re-establish Hyrule Kingdom like in Botw. The game seemed to have a hopeful ending but Botw's Zelda not re-establishing the Kingdom makes me think it may not happen there either.
- If its in the Child Timeline
- You either have to assume the Hero of Time was detailed enough in his recounting of his adventures to the Royal Family and that it was confused for Zora History or that the sages both awakened and very similar events played out to the Zora monuments.
There are many buildings like the Temple of Time that have to only be easter eggs under refounding which, while they are easter eggs no matter what, is like saying the town names of Adventure of Link don't necessarily mean its the same Kingdom as Ocarina. I understand that a confirmed intention is different to Totk with all of the perceived contradictions and actual contradictions but it feels like lot of explanations for the refounding require "destiny" or the Kingdom just happening to repeat the same architectural style as the previous Kingdom.
Really this just depends on the individual and if there is a limit for them on how many Doylist explanations are okay vs the wish for Watsonian explanation but sometimes it feels like people are discounting evidence just because it supports a theory they dislike. Though I understand why its important to keep them in mind like the Rito mural in Twilight Princess being confirmed to be a doodle by a guy for the HD version or the fact the depths contained what was DLC for Botw.
