In one swift, fluid motion, Neville broke free of the Body-Bind Curse upon him;
the flaming hat fell off him and he drew from its depths something silver, with
a glittering, rubied handle.
The slash of the silver blade could not be heard over the roar of the oncoming
crowd or the sounds of the clashing giants or of the stampeding centaurs, and
yet it seemed to draw every eye. With a single stroke Neville sliced off the
great snake's head, which spun high into the air, gleaming in the light flooding
from the entrance hall, and Voldemort's mouth was open in a scream of fury that
nobody could hear, and the snake's body thudded to the ground at his feet.
