Lux

A flashlight points in one direction.  You can't see what's behind you, without turning around.  But in doing so, you may lose what you were supposed to be looking for.

A lantern only shines so far.  You can't see beyond it's reach or what surrounds you, waiting and lurking in the darkness.  Taking a step forward is a gamble between life and death.  You could be devoured whole or left to die in pain.  But it may set you on a path that is scattered with gems that sparkle from your light.  You follow the shimmering road even when you can only see so far.  You don't know where it leads but it guides you nonetheless.  The gleam of the gems guide you through the darkness.  Where do you come out of when the path is at it's end?  Did you arrive where you thought you would?  Did your lantern fade and leave you in the pit of darkness?  Where are you?
