Luckdragons are among the strangest animals in Fantastica. They bear no resemblance to ordinary dragons, which look like loathsome snakes and live in deep caves, diffusing a noxious stench and guarding some real or imaginary treasure. Such spawn of chaos are usually wicked or ill-tempered, they have batlike wings with which they can rise clumsily and noisily into the air, and they spew fire and smoke. Luckdragons are creatures of air, warmth and pure joy. Despite their great size, they are as light as a summer cloud, and consequently need no wings for flying.
The Neverending Story, Michael Ende
