You are at a passageway leading down.  The walls that shine brightly
narrow as you venture further down.  The torches seem more spread out and
some of them are out.  However, it is still light.  You assume you must be
getting close to large lava flows.  As you look downwards, you feel eyes on
you.  You shiver in fear as you continue down the path.
