Swords Against the Shadowland is a fantasy novel by American writer Robin Wayne Bailey, featuring Fritz Leiber's sword and sorcery heroes Fafhrd and the Gray Mouser.

A later trade paperback edition was issued by Dark Horse in April 2009.

[1] It was projected to be the first in a series of authorized continuations of the Fafhrd and Gray Mouser saga by Bailey.

The Fafhrd and Gray Mouser stories follow the lives of two larcenous but likable rogues as they adventure across the fantasy world of Nehwon.

There, haunted by their lovers' ghosts, they combat a sorcerous plague cast on the city by a rogue wizard named Malygris, presumably named after the titular evil sorcerer in "The Death of Malygris," a short story by Clark Ashton Smith.
