  The seven eyes of Ningauble the Wizard floated back to his hood
as he reported to Fafhrd: "I have seen much, yet cannot explain all.
The Gray Mouser is exactly twenty-five feet below the deepest cellar in
the palace of Gilpkerio Kistomerces.  Even though twenty-four parts in
twenty-five of him are dead, he is alive.

  "Now about Lankhmar.  She's been invaded, her walls breached
everywhere and desperate fighting is going on in the streets, by a
fierce host which out-numbers Lankhmar's inhabitants by fifty to one --
and equipped with all modern weapons.  Yet you can save the city."

  "How?" demanded Fafhrd.

  Ningauble shrugged.  "You're a hero.  You should know."
