There is a place on the trail to Talonto Peak that might seem very inviting to a certain kind of explorer. It's likely to have a good view of the area. It's far enough from signs of habitation that nobody will be in sight, yet still reasonably close to what looks like an interesting, thriving village on a lake, pulsing with many small uses of magic.
If someone arrives here they would see a line of snowy plateaus a long way off, plus a nearby peak blocking other views to the south. A sheer cliff to the west and a trail up towards a mountain peak to the north. To the east, after a few switchbacks, there is a tall, ragged flag hanging from a wooden post and stabilized by a pile of rocks. The trail continues from there along a narrow path with sharp drops on both sides, past a curious shape that might be some kind of structure, and down to a river that one with a map would know leads to the interesting lake soon enough. One with even a rough map would also know they could take the fork in the trail for a steep but much faster descent towards the lake village.
Also, it's cold. Well below freezing. But that's not a problem for the properly prepared.
