The Grand Sentinus was wearing a suite and had charmed his hair to be shorted. He looked like a politician and this was the effect. A little while before he had killed the representative of France and taken his place. Now, the ministers were assembling and were ready to discuss foreign policy.
With access to the French Presiden't arsenal of muggle weapons, the Grand had ordered tanks to march on the UN building in Geneva.
He stood and spoke fluent french, "My allies and enemies, I come before you to declare a new empire. An empire of France. I have arms outside and shall attack this building immediatly. There is a way to prevent this: sign a treaty giving all territory and wealth to France!"
He was laughed and geered at until he gave the signal. Then the tanks attacked and everyone died in the rubble - all the world leaders...destroyed. Sentinus looked on his handiwork, already transformed back into the King Like Figure. The muggleworld was in turmoil.
