The black ooze slowly begins to recede as you move on, but it still clings to the floor, wet and sticky. You haven't fully emerged from it when the sound of the song suddenly sharpens, and you can make out where it's coming from--a passage just up ahead.

The passageways widen into a full, echoing cavern here, with multiple tunnels leading off from the sides. An arch of stone twists across the cave high above, and perched atop it is a young girl, no more than ten or so, with white hair and a white nightgown. She's the one singing.

There are three swords stabbed through her heart, and blood drips down to the floor from her body. Drip. Drip. Drip.
