I can see people are still curious about theories about Zelda's origins.
One of the most telling signs that Zelda depicts a flat world is it's story
of creation. Retold by the royal family and those guarding the coveted
TRIFORCE
Before time began,
before spirits and life existed...
Three golden goddesses descended upon the chaos that was Hyrule...
Din, the goddess of power...
Nayru, the goddess of wisdom...
Farore, the goddess of courage...
Din...
With her strong flaming arms, she cultivated the land and created the red earth.
Nayru...
Poured her wisdom onto the earth and gave the spirit of law to the world.
Farore...
With her rich soul, produced all life forms who would uphold the law
The three great goddesses, their labors completed, departed for the heavens...
And the golden sacred triangles remained at the point where the goddesses left the world.
Since then, the sacred triangles have become the basis of our world's providence.
And the resting point of the triangles has become the Sacred Realm.
Notice a couple things. When retelling of the story is going on, the Goddesses are raining down on the Earth and upon creation, create the energy and layout for the Earth in a BLUE FLAT DISK THAT EXPANDS. Watch it yourself if you don't believe me. Also, after the addition of Din's help, mountain scenes go by without so much as the slightest curvature visible from such glorious heights.
