“I am becoming an old man and can no longer go forth to battle. You must take my place and found new cities in the wilderness, for the kingdom of Wisdom must grow.' "And so they did. One went south to the Foothills of Confusion and built Dictionopolis, the city of words, and one went north to the Mountains of Ignorance and built Digitopolis, the city of numbers. Both cities flourished mightily and the demons were driven back still further. Soon other cities and towns were founded in the new lands, and at last only the farthest reaches of the wilderness remained to these terrible creatures and there they waited, ready to strike down all who ventured near or relaxed their guard.” NumbersWonderlandWackylandCloudcuckooland Book:The phantom tollbooth Source: The phantom tollbooth
