Honestly? That is almost exactly my thought. The magical forest where Simurgh lies never had unforgiving winters in the past either. With how Crystalism is now, they are ensuring a saturation of Light in the entire continent. Either his senses are heightened, or this is engineered in such a way that... he's receiving this excess of Light.
It eludes me. There are multiple magical seals crafted in such a way only a select few can pass through, and even getting to the shallower depths of it was difficult, as you surely remember. Thankfully, I did manage to retrieve what I needed that time.
They would most likely rally against me, as they were taught. Why did Erlantz build such a kingdom? Why are these lies woven so tightly? In any case, for now, I will tend to other matters before the situation worsens for us in other corners of the world.
