The Lost Stone Mansion 

         You stumbled upon a huge mansion deep in the woods while on a 
    hiking expedition.  In order to escape the impending darkness and cold, 
    you entered the seemingly-abandoned chƒteau.  While exploring, you found 
    a hidden doorway and a "secret" side to the big house.  You continue to 
    search around, finding odd items and encountering various creatures.  
    You try to find your way out of the mansion alive.  

         While exploring the mansion and its dark subterranean reaches, you 
    discover a mystery.  Apparently, treasure is hidden somewhere in the big 
    house.  You discover something else:  there seems to be evidence of 
    experiments, or hidden knowledge, concerning certain rare gems.  It 
    appears that something is occurring (or occurred in the past) in the 
    mysterious chƒteau regarding "photogenerative properties of rare gems."  
    Photogenerative properties -- the creation of light from gems!  

         Your mission becomes twofold:  escape with your life and solve the 
    mystery about the gems.  There seems to be no way to return to the front 
    entryway of the mansion and depart the way you came.  Or is there?  You 
    try to solve the riddles of the spooky old estate.  Soon the riddles 
    grow.  There seems to be evidence that someone else is wandering through 
    the mansion with you!  Or at the least, someone was in the house 
    recently.  You strive to solve the puzzles.  

         At each turn of events, the mystery grows.  Why is there a secret 
    part of the mansion, anyway?  How can you get back to the original 
    entrance?  What sort of treasure is hidden in the chƒteau?  What is the 
    secret about the gems?  Who else is wandering around the house, and are 
    they friendly or menacing?  Are there dangerous animals in the mansion?  
    Why are there so many curios in the house?  Who owns this mansion, 
    anyway?!  

         These and other questions haunt you as you maneuver through the big 
    chƒteau.  Fare thee well, fellow traveler.  I wish you great success on 
    your fated quest -- into the unknown -- of The Lost Stone Mansion ....
