Tail the high elf escort party

You decide to follow the beautiful elven party into the woods. Unfortunately, they disappear into the woods. "Where the hell did they go?" you wondered. It seemed that you walked further into the woods then you thought. You look around, but see nothing but more trees. You are lost. "Uh oh..." you say aloud. Then out of nowhere the ambience comes to dead silence. All is quiet. Birds, insects, wind, everything stopped. It then began to get dark, not darker like night dark, but greyer and more unnerving. Then out of the darkness a song was being sung. It was the most beautiful song you ever had the pleasure to hear. It drew you closer to it as you yourself walking towards it.

The song itself was sung by a woman. Then when you think you see the singer, a black sack is pulled over your head.
