Reluctant Heroes (Black Dragon Trilogy)

A bumbling old wizard and his incompetent assistant, a beautiful but domineering witch and a drunken ex-soldier. When the spirit of the evil sorcerer Mishtar threatens to break free from the prison that has held him for two hundred years, they are the only ones who stand in his way. Aided by a small flying lizard and a big red dragon they take on elves, cannibals, barbarians and Mishtar himself in their efforts to bind him and secure a safe future for the people of Middle Vooragh.
