i actually thought about that a few times :0 im not the only one!I could be really wrong on this, but could be be said that the Calamity from BotW is the start of the Downfall timeline? The Calamity started by Link dying or whatever.
Wait no, where did BotW Link come from?
Wait, isnt BotW started in a Ressurection Shrine? So it could be that the Downfall triggered the Calamity, and that BotW Link is OoT Link who died, triggering the Calamity, and the Shiekah or somebody took him to the Ressurection Shrine....? Any reason this is wrong? Or ways to build on it?
I was obviously thinking this up as I wrote it.
