how to get to this question mark Kaer Morhen? (The Witcher 3: Wild Hunt)

is most likely in a cave

There is just a mountain, as far as I remember, nothing more difficult (from the boat stupidly to the top)

climbed the whole cave, no, and you can’t climb the mountain (

there is a sign of strength - nothing more if my memory serves me - climbs around - there is a possibility

There is a chest. You go in a straight line from the troll cave (I did this), look for a slope with an angle of inclination (on which you can slide), go down. There will be a chest and Basilisk at the top (or someone else, I don’t remember anymore)

so you run, there will be a chest that the wyvern guards
