As you approach the dune, sounds become more readily apparent. It was hard to tell what they were beyond general rustling sounds, but as you carefully headed up to see what the source was, growls and other more gutteral sounds were noticeable.
Reaching the top, you could see down for a good distance, the sand sloping down into pocketed grass before the jungle soon took over. Close to the edge of the trees were four hunched figures. They looked vaguely humanoid, but despite being a good fourty or so feet away, you could tell something was off about them. They were gaunt, disturbingly so, and clothed in what looked like tatters of cloth more than actual clothes...and, from what you could tell, were all bent over something that you couldn't make out.
From the looks of it, they had yet to notice you and seemed focused on whatever it was they were all hunched over.
