You are before a spacious tunnel.  You wonder how long these tunnels can
go on for.  The warm and rocky walls are a good distance apart, allowing you
to stretch out a bit.  The pathway ahead appears dark despite the torches on
the walls.  The screams and cries get louder as you move on.  You shudder at
the thought that you might be the next one screaming.
