I dont know if anyone's really talked about this yet, but I was looking at some screenshots of Age of Calamity again, and I looked at this gif where Urbosa fell over.





And taking a look in the back, it's the interior of Vah Naboris (seeing the green electricity current) behind her.

So I looked at some of the other gifs, starting with Mipha's





That's definitely the interior of Vah Ruta behind her.

Then there's Daruk, where it's kind of hard to tell where he is





But looking at the floor, it's definitely the top of Vah Rudania.





With Revali it's really hard to tell where exactly he is, but he's definitely up in the sky given the clouds and rain. Maybe he's on top of Vah Medoh?

But there's also the laser. It looks like Windblight Ganon's laser beam.

They all look like they're fighting like hell, or about to fight in Mipha's case. Revali even got hit, according to his feathers exploding off him.

This is when they fought Thunderblight, Waterblight, Fireblight, and Windblight Ganon, right before they died.

This cutscene is going to destroy me
