The Eyes of the Overworld
The Eyes of the Overworld is a fantasy fix-up by Jack Vance, published by Ace in 1966, the second book in the Dying Earth series that Vance inaugurated in 1950. Retitled Cugel the Clever in its Vance Integral Edition (2005), the book features the self-proclaimed Cugel the Clever in linked stories.
The components of the fix-up were five short works published in The Magazine of Fantasy & Science Fiction from December 1965 to July 1966, and one original to the book.
Plot summary
Cugel is easily persuaded by the merchant Fianosther to attempt the burglary of the manse of Iucounu the Laughing Magician. Trapped and caught, he agrees that in exchange for his freedom he will undertake the recovery of a small hemisphere of violet glass, an Eye of the Overworld, to match one already in the wizard's possession. A small sentient alien entity of barbs and hooks, named Firx, is attached to his liver to encourage his "unremitting loyalty, zeal and singleness of purpose," and Iucounu uses a spell to transport Cugel via flying demon to the remote Land of Cutz.
