The place of power. How to get to this place? (The Witcher 3: Wild Hunt)

In my opinion in the story, with Keira Metz

Victor Salantai
The entrance to the cave from the water well on the cards.... In Velenje, much more than two, so look carefully.

what is a chest under the ground most likely. after completing the quest return to the mansion already no where throws the portal. miss something quite easily there.

offer a place of power in the quest the touch with Keir.at the very end of the quest,right before the exit of the cave..back at any moment of the game if you missed it during the quest

Victor Salantai
if I'm not mistaken,this place opens during the passage of the mission when you had to kill Imerica and 3 witches.
