There are a lot of little things here and there, such as everyone seeming to know you, even in far away places, and names of random people being the same.

So it’s definitely the same world, but at the start it’s just unclear how it fits in.

Some issues I have with it

- Ganon’s sealed away mummy had to exist in BOTW if TOTK is a sequel, so why didn’t Calamity Ganon unleash it? - Zelda does back in time, and reading some plot spoilers, she needs to be in two places at the same time in BOTW if it’s a sequel - everyone remembers Link in TOTK, but not in BOTW, so it must be after

I’m sure there are more issues as well.

The Zelda franchise isn’t big on plot, so I’ll treat TOTK as a separate timeline/universe from BOTW for it to make any sense.
