L Frank Baum
"One of my greatest fears was the Witches, for while I had no magical powers at all I soon found out that the Witches were really able to do wonderful things. There were four of them in this country, and they ruled the people who live in the North and South and East and West. Fortunately, the Witches of the North and South were good, and I knew they would do me no harm; but the Witches of the East and West were terribly wicked, and had they not thought I was more powerful than they themselves, they would surely have destroyed me."
