(AOC stands for "age of calamity" if you're confused)

after discovering what's at the bottom of the yiga clan pit, the champions, zelda link, impa, and terrako were sent to investigate whatever else is down there. When they get to the bottom they see the place is actually as bright as the surface due to huge light plants that connect to the surface. They also find what look like zonai devices like wheels and elemental emitters on a nearby vehicle construction spot.

Daruk: wow... this place sure is different...

Revali: atleast there's still lots of space to fly, unlike most caves.

Urbosa: who would of thought all of this was right underneath our feet.

Mipha: it certainly is quite a sight...

Impa: be wary, no telling what lives down here.

Zelda: impa is right. Now we should get going, right Link?

Link: nods.

Terrako: beeps and whistles curiously.

Master kohga: what are we waiting for then? let's go! he was clearly excited to explore.
