Visit to the graveyard
     Complete  the  game  once, save your game and load your completed
game  save.  A  new  map,  The  Graveyard,  will appear. Now go to the
colosseum  and  fight  through 10 battles. You will receive a piece of
equipment (a pendant) that nobody seems to be able to equip. Visit the
Graveyard with the pendant, and a special event will occur.
