Translated from the back of the book:
"'The year of the Griffon I'
Just as the battle at the Silkwiesen has been decided, the heroes are led by Colonel Marcian of the KGIA, the imperial inquisition, on a secret mission to the north. They are supposed to instigate insurrection in orc-occupied Greifenfurt and hold this important border town until the imperial relief force arrives. But instead of the prince an orc general turns up at the city gates; and the mysterious murder of the bakers daughter further unsettles the townsmen.
These two adventure modules contain a campaign featuring the struggle for Greifenfurt, lasting more than a year. Included are a description of the city and its most important citizens as well as material for further interconnected adventures."
