The party is led to the burnt out stump to the north. Upon reaching the shore one of the lizardmen await you at what appears to be an entrance in the base of the stump. Peering into the murky blackness, you can see that the tunnel widens into an 8-foot-high tunnel that descends slightly. The roof of the tunnel is cluttered with taproots from the cypress trees above.
The lizardman guard leads you inside. You first enter a cold, damp, 30-foot diameter cavern whose floor is a mass of puddles. The 30-foot-high ceiling is a mass of dangling roots from the cypress trees above. A pair of lizardfolk guards stand at a narrow exit in the northwestern corner.
You follow the lizardman through a narrow tunnel to the northwest into a larger chamber. Swamp water drips from the ceiling and pools on the muddy floor. This area is obviously a guardroom, which leads to an alcove that holds weapon racks. In the northeastern corner, a tunnel leads east. In the center of the room is a stout table behind which crouch two lizardfolk armed with fishing spears.
The lizardman your following only stops momentarily to acknowledge the two others in the room. They eye the party suspiciously. Moving on leads to a narrow 5-foot tunnel, winding in a north-easterly direction, that then widens and opens into a large, roughly hewn chamber. The chamber is in total darkness save for a faint glow emanating from an opening in the eastern wall. The slight clink of chains can be heard from various parts of the room. The guard does not slow in this room at all, leading you onwards further.
You quickly pass through a natural chamber with a very high ceiling. The eastern wall of the room is almost entirely dominated by a clear pool, lit by phosphorescent mosses that coat the slimy walls.
Breaking the surface of the water, a large cave becomes visible. The walls of the cavern are thick with hanging vines, behind which you can make out humanoid shapes. Waiting for you on the "beach" is an enormous lizardman, easily 7 feet tall, holding a greataxe that glows with an eerie light in the gloomy cave. Behind him is a large, writhing serpentine shape that shimmers green in the light filtering in from an opening in the ceiling. The snake creature has a nightmarish mockery of a human head and it's forked tongue between dripping fangs, tasting you on the air as orange hackles rise on the back of it's head.
Looking around you on either side you can finally make out the humanoid shapes. On one wall two halflings, twins by the looks of them, stand staring forward, glassy eyed expressions on their faces. Opposite this wall 2 more stand, a gnome, and a beautiful elven female, both too, with emotionless, glassy eyes. None of them move at all, nor do they appear to notice your arrival into the chamber. They just stare straight ahead, as if simply awaiting orders...
