the sunken cave is in the calm lands acutally... you know where the monster arena is... go directaly north from there until you get to the path that leads to a new screen, as if you were going to mt. gagazet... now cross the first bridge and go to the left until you go to another screen, then go left once your there, its the only other way to go on that map... thats where it is... if these directions confuse you, write back and i will make them easier (more elaborate)
