I got this quest and cannot access cave with apprentice:
Silent Daigon
Current goal: Go to the apprentice and ask him for Candied Fruit for the Daigon.
I kept getting this message when I click on cave: One of the many caves on the Isles of Swirling Mist.
I was told I needed another quest which I went and got:
The Lost Apprentice
Current goal: In the Azure Lagoon, find the cave in which the apprentice has taken up residence, and find out what has happened.
When I click on the cave I am still getting: One of the many caves on the Isles of Swirling Mist.
