You are in a gloomy hallway running north/south.  The dark and hot walls
seem to narrow as you continue on.  The hallway is lighted by small torches
well spaced out on the walls, which gives just enough light to see two feet
in front of you.  Faint cries and screams echo off the hallway walls.  A
chill runs down your spine as you make your way farther down the dark and
gloomy hallway.
