Spoiler Warning!!!: Plot and/or ending details of a Fighting Fantasy publication follow. Please DO NOT read this article if you do not want foreknowledge of this publication. Although the article below is based on canon, some of its content is considered extrapolation because it assumes a certain course of events through an adventure that has many possible routes. Finally, the use of "Hero" and other male- gender expressions pertaining to the subject in the article and/or title of the article is not intended to exclude the possibility that the hero was female.
The Hero of Rogue Mage was apprehended trying to steal from the stall of a fat merchant in Wolftown after the money won during the hero's last adventure ran out, leaving him or her starving and penniless. The hero was sentenced to serve the Wizard's Guild by defeating Galthazzeth, a sorcerer expelled from the guild a decade earlier.
The hero entered the mines where Galthazzeth had made his lair and killed him, earning the thanks of the Guildmaster and freedom from the theft charge, but no monetary reward.
It is possible that the hero also took part in other books, either before or afterwards. He or she began the adventure with a shield, as well as the usual equipment.
