A short tunnel lead into a large area beyond the illusory wall. Many hands had worked this natural cavern over the years, digging out shelves and niches, carving lewd pictures into the sandstone walls, and constructing an enormous statue of a pregnant, jackal-headed woman that occupied the southern side of the room. To the south, behind the statue, were a couple of sandy steps leading to a pool filled with crystal-clear water.
Four more cultists, similarly dressed as the once guarding the entrance, lounged in the cavern. One was lying on the ground resting, two were playing cards in the flickering light of a candle at a small wooden table, the last one was busy eating what looked like foul, raw meat.
Two more creatures were visible as you entered, just coming out of the pool, the skin on these frog-like fiends was still wet and dripping water, their eyes looked dead and milky; the wide faces split by a fanged maw.
As Zhira assumed, none of these dwellers in the cavern seemed to be overly concerned about the large-scale battle that had been fought at the foot of Blood Rise Rock not 10 minutes ago. All looked rather shocked and surprised as the party arrived, illuminated by the bright-glowing form of Qvan's new shape.
Those would be Hydrodaemons. Like the cultists, posing no threat to your party at all.
