OOC: Sorry for the delays...just getting back on track after my vacation.
You follow the trail southwest, along the edge of the lake. The water is dark and scummy, clogged with reed, duck weeds and lily pads. Frogs splash into the water, water snakes swim quickly between clusters of growth, and swamrs of stinging insects are everywhere. Sandor even points out several crocodiles lying in wait in the waters, cautioning you from entering the lake.
After a few hundred feet, the trail turns away from the lake, running through the dense growth of the marsh once more. You find yourselves quickly approaching the cliffs on the western side of the rift, and as the swamp begins to give way to firmer (though still soft) ground, you find yourselves in front of three clefts leading back into the rock. Each opening is about five feet wide, and leads away into darkness.
You can see ruined buildings rising above the foliage some hundred feet to the south of your position.
