Fafhrd and Gray Mouser
created by Fritz Leiber
Fafhrd and the Gray Mouser are two seminal sword-and-sorcery heroes appearing in stories written by Fritz Leiber (1910–1992). They are the protagonists of what are probably Leiber's best-known stories.
Fafhrd is a tall (seven feet) northern barbarian; Mouser is a small, mercurial thief, once known as Mouse and a former wizard's apprentice. Both are rogues, existing within a decadent world where to be so is a requirement of survival. They spend a lot of time drinking, feasting, wenching, brawling, stealing, and gambling, and are seldom fussy about who hires their swords. But they are humane and—most of all—relish true adventure.
The characters were loosely modelled upon Leiber himself and his friend Harry Otto Fischer (1910–1986). Fischer initially created them in a letter to Leiber in September 1934, naming at the same time their home city of Lankhmar.
