I found the ancient story about wish cave... The Wish Cave is way north. In some woods, a magical being guards the entrance, blah blah blah.... after defeating it leads you to the cave.... blah blah blah... At the end of the cave some goddess challenges you to a battle of wits, blah blah blah, if you lose you are banished from the cave forever, blah blah blah, and if you win you can have one wish and leave safely, blah blah blah.
