(hafrogman, I assumed Keoni had already searched the clearing and immediate area with the previous Search and Survival skill checks...hopefully, that's good enough to satisfy his suspicions. As has been pointed out, it would be a lengthy and daunting task to search the whole of the island, as it is primarily dense jungle and rocky cliffs. No other path has presented itself, other than the hidden one which led from the beach to the clearing.)
Shefton jumps as Chongo thumps his on the shoulder, apparently slightly nervous thanks to Anar's comment. Clearly, the guide doesn't want to be anyone's plaything. "Right, mates, I'll wait up here a while for you. We can talk payment when you get back."
With Shefton having already opened the trap door, Keoni and Chongo look it over carefully. It's heavy and made of stone, with hinges and no visible lock. There is a stout rope hanging from a hook in the wall that leads down into the five-foot-wide shaft. No other means of descent is apparent.
Okay, are guys going to climb down? If so, I'll assume a similar order to the one used in the vault...Chongo, Anar, Kalen, Keoni, Col, Bael.
