This area is pretty useless, but, if you explore you will find something amusing:) Try searching every one of those little pink flowers you find in Merthuns' Cave. Once you've explored 10 of them, Herasia and Random will get tired of hearing Sarah say that she wishes she could have one in her bedroom. From that point on, Herasia is keeping track of how many times you had to hear it:) It's not important to the game, but it's amusing. Since there are only 3 items in this part of the cave, I think the map is pretty self explanatory. In the entire cave you will find 5 Sharks (frozen Shark meat), a Diamond, and a Trout.
