The Dying Earth series by Jack VanceWiki quote:
Dying Earth is a fantasy series by the American author Jack Vance, comprising four books originally published from 1950 to 1984. Some have been called picaresque. They vary from short story collection to fix-up (novel created from older short stories) perhaps all the way to novel.
The stories of the Dying Earth series are set in the distant future, at a point when the sun is almost exhausted and magic has reasserted itself as a dominant force. The Moon has disappeared and the Sun is in danger of burning out at any time, often flickering as if about to go out, before shining again. The various civilizations of Earth have collapsed for the most part into decadence and its inhabitants overcome with a fatalistic outlook. The Earth is mostly barren and cold, and has become infested with various predatory monsters (possibly created by a magician in a former age).
The series comprises four books by Vance:
