Korb lead the party members away from the caves and up the stairs to the chamber where the walls are smeared with Terran sigils and letters. The way goes back from here to the entrance and other parts that you have not explored or down the second natural stairs to where Thandis spotted more of the horrible and smelly Trogs.
Dei hefts all the extra gear he is carrying and wonders which way the dwarf will go. He secretly hopes not in the direction of the foul smelling trogs.
There are faint sounds of activity of humanoids doing mundane things from the stairs that leads down to where the Trogs dwell.
The south passage leads back to the entrance where you came from and to the doors and rooms you haven't visited yet.
