The Entropic Battles
Dirgues are large, almost Gigantic, domicile creatures. Easily domesticated, these creatures are Mobile farms. With their back being covered in a rich Soil-like substance Flaked from their skin, They are capable of growing almost any plant, given the right diet (and Temperature). The soil temperature is kept above the frost level by friction caused by internal friction from the saplike blood that flows through them.
Despite the huge size, they are almost glacially slow. Cooking them has never been proven to provide any good meat and is almost universally considered in poor taste. Some people theorize it is the Bitter sweat sap in the blood, or the Soil like skin.
