The Dancers at the End of Time is a series of science fiction novels and short stories written by Michael Moorcock, the setting of which is the End of Time, an era "where entropy is king and the universe has begun collapsing upon itself". The inhabitants of this era are immortal decadents, who create flights of fancy via the use of power rings that draw on energy devised and stored by their ancestors millions of years prior. Time travel is possible, and throughout the series various points in time are visited and revisited. Space travellers are also common, but most residents of the End of Time find leaving the planet distasteful and clichéd. The title of the series is itself taken from a poem by a fictitious 19th-century poet, Ernest Wheldrake, which Mrs. Amelia Underwood quotes in The End of All Songs. "Ernest Wheldrake" had been a pseudonym used by Algernon Charles Swinburne.

Star Maker is a science fiction novel by British writer Olaf Stapledon, published in 1937. The book describes a history of life in the universe, dwarfing in scale Stapledon's previous book, Last and First Men (1930), a history of the human species over two billion years. Star Maker tackles philosophical themes such as the essence of life, of birth, decay and death, and the relationship between creation and creator. A pervading theme is that of progressive unity within and between different civilizations. Some of the elements and themes briefly discussed prefigure later fiction concerning genetic engineering and alien life forms. Sir Arthur C. Clarke considered Star Maker to be "probably the most powerful work of imagination ever written", and Brian W. Aldiss called it "the one great grey holy book of science fiction".
