Lore: The  Deogen; a ghost who haunts the Alekuvan Library. He is known
to brutally murder anybody who dare set foot in his terrain. There are
no known survivors that ventured into the hunted building. Will you be
the first? Or will you join the many souls he has claimed?

So this mini game is pretty simple. One  person is chosen to be the
"Deogen" and the rest are placed into the maze/library. The objective of
the brave souls who accepted the challenge is to score 3 points by
locating the active pressure plate. There are 8 pressure plates around
the dark maze, BUT only one works. The plate is chosen at random every
time. The "Deogen's" job or "purpose", is to stop the trespasser from
scoring 3 points by brutally murding them! So, do you think you have
what it takes to survive? Or will you fall victim to the Deogen?

Tested only in Minecraft version 1.7.2 so I can't guarantee it to work in older or newer versions.
