One of the scientists lies on the ground, mortally wounded.  Before she
dies, she explains to you that you must destroy the monster before it gets
out into the castle.  Before you can ask her any questions, she doubles over
in pain and dies.  
A castle guard tries to keep alert during his long shift.
