The Fields of Frotzen, fertile farmland in the heart of Gurth province between Gurth City and Grubbo Hills, produces an annual bounty of grain and are frequently referred to as the Breadbasket of Quendor. Renowned for their incredible agricultural capacity, seeds that are planted within the fields often ripen withing days. This attribute has made it the second most abundant agricultural region in the Westlands. These fields are home to packs of giant screaming corbies which wheeled in tight menancing circles overhead in massive flocks. The last known specimen of the compass rose grows there in a small grotto. The location that is equivalent to Frotzen in the Ethereal Plane of Atrii is the home of the Implementors.

While the Fields of Frotzen today are colorless and prone to frequent storms (which made travel in the area very difficult), this was not always the case. Prior to the end of the First Age of Magic, a dark magical event (perhaps the Triax) was the cause of these defects. Afterward thunderclouds continually boiled with dark energy and the now colorless landscape was mottled with rocky terrain and windswept tracts of grass stretching in every direction as far as could be seen in the storm-driven wind. One was unable to even enter the fields without carrying the proper chalice of the Implementors. Small gray farmhouses were frequently dumped out of the clouds into the Fields of Frotzen during the raging storms. The only known way to reach the forgotten land of Froon is by riding one of these homes upon the winds of a tornado.

By the Great Monster Uprising of the Second Age of Magic, the fields were once again golden. New farmers and windmills were erected and farmers havested the plentiful land. Unfortunately, this age infested the fields with all manners of foul beasts and adventurers. Animated scarecrows were employed to fend off the flocks of giant corbies, but many of these went awry, turning upon their creators.

Those that are obsessed with trivia might like to know that the distance between signposts in Frotzen is 120 bloits, as well as the fact that the first suitor of Morning-Star was sent by Queen Alexis across the sea to beg Lord Nimbus, the so-called "God of Rain," to quench the thirsting Fields of Frotzen. Farmers are also in the habit of actually setting up maize mazes, which have been known to be a quality source of complementary income.
