Of course each one of them expected to see the Wizard in the shape he had taken before, and all were greatly surprised when they looked about and saw no one at all in the room. They kept close to the door and closer to one another, for the stillness of the empty room was more dreadful than any of the forms they had seen Oz take.
Presently they heard a solemn Voice, that seemed to come from somewhere near the top of the great dome, and it said:
“I am Oz, the Great and Terrible. Why do you seek me?”
They looked again in every part of the room, and then, seeing no one, Dorothy asked, “Where are you?”
“I am everywhere,” answered the Voice, “but to the eyes of common mortals I am invisible. I will now seat myself upon my throne, that you may converse with me.” Indeed, the Voice seemed just then to come straight from the throne itself; so they walked toward it and stood in a row while Dorothy said:
“We have come to claim our promise, O Oz.”
“What promise?” asked Oz.
“You promised to send me back to Kansas when the Wicked Witch was destroyed,” said the girl.
“And you promised to give me brains,” said the Scarecrow.
“And you promised to give me a heart,” said the Tin Woodman.
“And you promised to give me courage,” said the Cowardly Lion.
“Is the Wicked Witch really destroyed?” asked the Voice, and Dorothy thought it trembled a little.
