Alright.
Where does BotW take place relative to A Link to the Past?
In the far distant future of
A Link to the Past, per the countless accounts of Aonuma and Fujibayashi of
Breath of the Wild taking place at the end of the timeline.
firstly, the apparent fact that the alttp arc doesn't matter since it didn't happen, and also how the four swords arc doesn't go FS>FSA, it goes FS>other unrelated games I guess>FSA
I and others have openly discussed in comments in this thread how the “official” timeline was put together by fans and has nothing to do with Zelda Team’s actual opinion in regard to the timeline. This is why
A Link Between Worlds - literally the first new game after the Hyrule Historia released - ignored the modified account of
Ocarina of Time and
A Link to the Past’s backstory and instead continues using the original
A Link to the Past backstory as described in
A Link to the Past’s manual.
Furthermore, as this was not picked up on by the Hyrule Historia staff, the game and the Japanese website explicitly reveal that
Four Swords Adventures is a direct sequel to
Four Swords with the same Link. Hence why the FSA intro describes the FSA Link and Zelda as the same cast as the characters from FS.
