ZORK I Part One

 So, you're all set for The Great Underground Empire, eh?  Okay,
but before we begin, a few words about this walkthru.  First,
this is not the only way to solve the game.  It's just one of the
faster ones.  Second, because there is no "wasted motion" in this
game, you will not be visiting all the locations.  So, you might
want to play around with the game on your own for a while,
mapping out as much as you can, without much regard for gathering
treasures. Actually, mapping is a good idea, since, if you make a
misstep somewhere, you might find yourself in trouble!  Be
especially careful to follow the directions when in the mazes;  a
wrong move there, and you could be lost for quite some time!  
Finally, you may not go through this in exactly the way it's
written because of the thief. He is a variable item in the game; 
you never know where he will show up.  Try to move out of the
room he's in as soon as he shows up.  But keep in mind that even
if he does steal anything from you, you will get it all back from
him in the end.
