The prua was a domestic breed of woolhog that existed in the Jade region of Frauji. Adults often weighed over 100 kilograms and stood 80 centimeters tall, covered in striking wooly, green fur. The tips of their ears and tails had extended tufts, and males had prominent facial whiskers. 

The prua shared a name with a species of seasonal moss from Frauji, both of which get their green hue from the same source. In the late 6th Age, it was discovered to be the result of an ancient species of phytoplankton that made up four percent of the soil in the territories of Jade and Hilsi-Kile. The plankton likely originated from the Verdant Sea trillions of years ago. As a result, these regions were home to incredibly fertile soil, but had the side effect that those who consumed local plantlife developed green terminal hair. 

The species was domesticated in the late 7th Age and became a primary source of food and hide following the Solstice War, making them a valuable trade commodity. Professional pig keepers became known as “prueba” and were highly respected individuals in their towns, their farms often acting as the village center for events. 

Consumption of woolhog was not common for Eavons until after the Solstice War, their ability to grow quickly and eat almost anything making them easy livestock. As much meat was taken from the animal as possible; the fattier portions are made into salted and honeyed bacon, the leaner portions are diced and spiced to make kebabs, and the bones are used for broth.
