After going to Gadel, go southeast. At the bottom of the continent, there is a cave with a girl in it. Talk to her, then return to Gigarl. There is an old man in Gigarl who will be interested of your findings. You will have to go back and forth between Gigarl and the cave. After a few messages, the old man will come with you to the cave and be turned young again. This scenario will provide you with nothing unless you haven't searched the pots.
