idk if anyone has noted this detail yet but..
If you drop down into the Yiga Clan Chasm, you'll see a small patch of gloom at the bottom. It's the only immediate patch there.
Coincidentally, if you fall down at the exact point Kohga fell, after the ball rolled him off the edge, you'll land close enough to it.
and what would you know? There's a boulder right next to it, off to the side.
