The description gives a clue to a certain subtlety to this quest, or at least the game environment in which it takes place. Players experienced in other games will expect events to take place either above ground, or in a closed space like a house or dungeon. Caves are almost always the latter, but in PW, spaces are sometimes both enclosed and open to the outside. Take the ramp to the south of the Elder, and it curves back around into a cavern. Just looking at the coordinates and following them would lead the player to the top of the cliff, none the wiser as to Chen the Referee's location
