the scrying The spell allows you to place an invisible sensor anywhere you've seen before. You can see and hear through the sensor as if you were there
Imagine this scenario: I've already seen the summit of a mountain by far, so I decide to use scrying to create a sensor. From the top of the mountain using the sensor, I can see the top of another mountain and I use it later scrying to see from the top of this mountain, and so on.
As written, it seems that "seeing" a place using the prediction spell allows you to see it from that location later using the revelation spell. Is it correct?
