Grab your dress and head further up the trail

The serpent has left you exhausted, but unsatisfied, the ache between your legs driving your deeper into the woods. You put your dress back on and follow the trail into the forest, winding uphill to the mouth of a large cave. Old bones litter the ground around the stone maw and the rocks are glazed shiny black, as if scorched by hellfire. This looks like the lair of a dragon.

Beyond the cave, you see the path continue on up the hill, and in the distance, you can see an old, ruined tower.
