The boat flows smoothly forward.

[Tunnel of Sorrow]
The harsh song of a raven cuts across the silence like a jagged knife. Other birds, unseen in the reed beds along the shore, join in, making an atonal screeching fit to annoy the dead. To add to the painful melange of sounds, the boat itself creaks ominously, as though some crucial nail or bolt were giving up the ghost.
Obvious exits: none.
