You're tasked with "deciphering" 3 locations based on the clues they provide. You have to find a red shooting star in a certain direction from
- the skull's left eye
- the biggest bridge in Hyrule
- the peak of a snowy and spiky mountain

The first one was easy, considering there was already a shrine quest dedicated to it. Go to the left skull's eye and wait 30 seconds looking in the specified direction. What's interesting is that Dinraal spawned overhead, but like, way overhead. He definitely has the most sporatic spawn locations of the 3.

Next I went to Hyrule Bridge and lo-and-behold, another red meteor. At this point Farosh spawned from the lake. The final location was the least specific, but not really too difficult to narrow down either. I figured that because Dinraal spawned at the first location, and Farosh the second, Naydra's spawn location would be tied to the last. And the only snowy location with her visible is the Spring of Courge on Mount Lanayru. Unfortunately this didn't turn out to be the case and the final meteor was located at the top of Hebra Mountain. Just a funny little disappointment for me, I dunno.
