from the introduction to the text

There is a word in the tongue of men that means at once slovenly, forgetful, daring, and creative. The word is marevous, from marev. There is no corresponding word in Drauvien, because the gods would never admit to being forgetful or slovenly, and so they would never combine negative aspects that they ascribe to others, with positive aspects that they claim only for themselves.

The Drauv claim that they created grain and fruit and milk, and that may be true. But it is a point of historical record that we ourselves discovered bread, and wine, and cheese, and beer. Marevous women and men made mistakes, and from the mistakes they forged methods, which over time became beautiful traditions that we are all thankful for. Even the Drauv themselves partake.

To allow the labor of your harvest to mix with the wild potency of the land and air is foolish. To transform the result into a new, finer harvest, is Marev, one of the Nine Essential Tricks of the Dragunne.
