200 years ago, the great wizard, Zeen Nolander, devised a solution to the negative energy plaguging the land of Serenita HappyNet™!
HappyNet™ (composed of 6 star-shaped bits suspended in the air above the nation) absorbs the negative energy and converts it into positive energy. This now positive energy is beneficial to plants, animals, and people (and their moods). A few technical minded folks have even found a way to power grist mills.
This national change in mood helped end the war with the nation of Keebler.
