The Spriggan Mirror: A Tale of Ethshar (Ethshar Novels)

Every wizard in Ethshare knew that if you needed something special, something difficult to find, that Gresh the Supplier was the man to see. He was expensive, but always delivered. So when the Wizards' Guild finally got fed up with the little green nuisances that called themselves "spriggans," the Guild hired Gresh to fetch them the magic mirror that had created the troublesome imps in the first place. The wizards thought finding it looked impossible. Gresh thought his methods would do the job.

But no one had asked the spriggans what they thought!
