I feel out of all pieces of evidence for a true founding, this is perhaps the most important. It straight up tells us the first emergance of Ganon/Calamity Ganon, and it's a description what matches perfectly with Ocatina Dorf, and simply does not match TOTK Dorf. Meaning either: -TotK Ganondorf came first -CaC is completely retconned

That ain't it, that's an AI summary of Reddit threads that believe TOTK retconned CaC. Here are two quotes from CaC. Both of them say that a Ganondorf (that matched Ocarina Ganondorf, and does not at all match TOTK Ganondorf) transformed into Ganon, got sealed time and time again, eventually becoming what's known as Calamity Ganon. And TOTK tells us where Ganon originates from. For Calamity Ganon to be seperate from Ocarina Ganon, one of the following must be true: 1. Creating a Champion's backstory of Calamity Ganon must be completely scrapped. And there's no indication (or reason why) that BOTW gets its detailed Ganon lore fully retconned in the game's direct sequel. 2. The backstory of Calamity Ganon = Ganon is still what in-universe characters believe, but the truth is that TOTK Ganondorf and Calamity Ganon are seperate from the original. Which means myths of the OG Ganon still exist, which makes it very, very weird why this was never brought up at all when a new Ganondorf came along. 3. The Ganon-emerges events from the timelines in the two Wild books, that are identical in their wording, must be completely seperate events, even though the events that follow (the Sheikah becoming advanced) are the exact same on both timelines

CaC (the BOTW book) says, quite clear, that Calamity Ganon and Ocarina Ganon are the same. MW (the TOTK) book) says, quite clear, that TOTK Ganondorf gave birth to/spawned/created Calamity Ganon. Put them together. TotK Ganondorf is the origin of Ganon. It's actually shockingly simple.
