You take a bite, and burn up you tongue and throut. The balrog laughs
at you. You lose the ability to eat things without getting
indigestion. You are forces to go to the hospital, because of the
indigestion you got from eating all 100 shadows. When you come back
from the hospital, you forget about the magic you learned and promise
never to go near the castle again. You can still, however, hear the
balrog's laugh ringing in your ears, and you will countinue to for the
rest of your life.
