Well, this Hyrule is the one underneath the sea in Wind Waker (also the one seen in Ocarina of Time). Koroks and potentially King Daphnes are there. The Temple of Time is there, but ruined after however many hundreds of years.
"But Ganon is sealed away after OoT, and isn't released until right before WW!" Yes Ganon does return, but not normally. He's the fog around Hyrule Castle. Say hi, he's been going through some hard times.
So even though Ganon wasn't actually released, part of his dark power or w.e. is getting through the sages' weakened barrier. So possibly the final boss isn't Ganon, but whoever is trying to free him?
"But Hyrule is flooded before Wind Waker, how could it be the same?" Well, time to brush up on some history. Take out your textbooks, because teacher Zelda is here to give you some Hyrule Historia.
(Never thought this would be used with any actual context) The Great Flood happened hundreds of years before Wind Waker.
Hundreds. BOTW Link was asleep for 100 years. The game could have taken place multiple times between OoT and WW. It may have even been
thousands of years between OoT and WW, since the legend of OoT Link is a, well, legend, and they messed up a few of their facts. (Boys put on the hero's clothes at
12?? OoT Link was younger than that before the Master Sword's insta-puberty-skip time warp happened, 10 iirc.)
Now to link their similar fashion. This was my big "aha!" moment today. Here's a quick side-to-side look.
The blue is almost the same (going to blame lighting differences and the fact that 1 is a game model and the other is artwork). No hat. White designs on their tunic. Hm... I'm going to remind people of Wind Waker's second quest, where he was given the "Hero's New Clothes" that were just invisible and worn over his pajamas. I thought this was a reference to "you beat the game, so you're the new hero so these are the clothes the hero should wear now" but what if
BOTW Link is the New Hero they used this design with? They weren't exactly spot-on with OoT Link, so they were probably a bit off with this outfit as well, hence the different design and orange pants. Also if OoT Link was the old hero and BOTW Link is the new hero then, yep, that puts BOTW right between OoT and Wind Waker yet again!
Finally the Koroks. Well let's just do a quick check on what the Koroks are.
Zelda Wiki said:
The Koroks are said to have once been the race of humanoid children-looking creatures called Kokiri. The Koroks became these creatures when they gave up their human selves for the ability to fly, with the help of an item called a Deku Leaf.
So after OoT, they got tired of standing in 1 place in a forest for all eternity like any other NPC so they tried flying and it worked out. Cool. So they probably changed while Link was sleeping for those 100 years. What's strange is how they look
identical to the Koroks in WW, just like the old man looks like King Daphnes.
(There's 3 other koroks shown in BOTW and they also have twins in WW, I'm just showing this 1). Same leaf shape, same body shape, same color, EVEN THE EYE AND MOUTH PATTERN ON THE LEAF ARE THE SAME.
