The Betrayal

I am in a holy, sacred, underground room.  The room possesses great power.  Only those who are immune to using their power inappropriately can access this room.  Only those who use their power for the good of all can access the room.
In the center of the room is an enormous cauldron that is a porthole to the core of the earth.  A beautifully etched and carved metal lid, shaped as flower petals covers the cauldron when not being used.  I am in the room when someone enters, someone who has disguised herself to look exactly like a male member of my family.  She has come to kill me.
