"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. They swim in the air of heaven as fish swim in water. Seen from the earth, they look like slow lightning flashes. The most amazing thing about them is their song. Their voice sounds like the golden note of a large bell, and when they speak softly the bell seems to be ringing in the distance. Anyone who has heard this sound will remember it as long as he lives and tell his grandchildren about it."
