I have an idea I got from another game system, and thought it might make an excellent Fantasy Hero adventure.
Dwdal Valmek was a dwarf brewer that developed magic to enhance the taste of his beer. As a gift to the Royal Family, Dwdal gave the King Hardin his crowing achievement, a book called "Dwdal's ancient brew master guide." The beer brewed from this guide has a significant magical effect. It is so delicious that after a single glass the drinker refuses to drink any other beer or other forms of alcohol. The King quickly perceived the danger in such a book, and quickly hid it in the hands of his most trusted brew masters. Over time, whispers of the magical guide has reached the ears of other Dwarven Kings. It has been at the center of numerous political intrigues, and outright hostilities. Thankfully, word of the book has been isolated to Dwarven royalty... until now.
The brewer's guide has been stolen. Should it be used to brew beer and others drink of it, the affect would be wide reaching and extremely severe. Wars, economic collapse, or even conquering the entire world by the power of beer.
Obviously, the brewer's guide will need to be discreetly retrieved. Those who know of it will need to be silenced, etc.
Meta plot: Taken directly from Never Winter nights, an ancient race of evil doers is attempting to take over the world. This adventure is the first time the party perceives someone is discreetly pulling strings.
So, what do you think? Also, how would make the book?
