Kvalheim Isle

This herbalist hut is located south of Blandare on Ard Skellig.

When Geralt discovers it for the first time, it's controlled by bandits. Once the area is cleared from the gang, the unnamed herbalist who was held hostage will reunite with his kin. For some reason he is reluctant to sell his stock at first, and will test whether Geralt is knowledgeable in herbs before trading. He also plays Gwent.

It's not clear why this location is called Kvalheim Isle, since it's in the middle of Ard Skellig.
