Ohhhh! How dare you not put The Minish Cap first! I will give evidence!
About The Minish Cap...
Hyrule - not an island, a pre-flood trait.
Dominant Hylians - Lots of Hylians in this game, but they are almost extince after the flood, Hylians were common during and before Ocarina of Time,
there are very few left after the flood.
Hero's Shield - Link's grandmother in The Wind Waker tells him that the yellow Hero's Shield had been by another hero long ago; during The Minish Cap, the Link of that time is given the shield by Zelda for the first time, when it is new, and becomea a hero with it, so The Minish Cap Link was referenced in The Wind Waker
Mirror Shield - The Blue Mirror shield that Link used in The Wind Waker was first created in The Minish Cap, explaining its origins
The Third Zelda - Tetra is the
third Zelda, meaning that there were two Zelda before her: The Minish Cap Zelda and the Ocarina of Time Zelda
Landmakrs - The Minish Cap seems to explain the origins of the common Hylian landmarks: the Goron are looking for a home, Veil Falls will become that home, Death Mountain; Kakariko Village has always been in a hole-like are with a carved mountain path going down towards it... Veil Falls has a waterfall going down into the hole that is Lake Hylia, meaning when the water stops, there will be a hole left and a mountain path where the waterfall was; if the water stopped, Castor Wilds would be over-filled with water and become a lake in the south-west... Lake Hylia in Ocarina of Time and Twilight Princess is in the south-west.
