[Text from the Field Guide to the Beasts of Illusao]
The tuskow is an entirely domesticated beast found only in the care of humans. It is not typically kept as a companion, rather it is used as livestock. Most of the tuskow's body will be used after it is killed, particularly its meat, hide, fat, tusks, and bone. Females also produce milk. Tuskow have four tusks, two on the top and two on the bottom. Due to these tusks, the tuskow cannot easily gather plants and grass to eat with its mouth. It has developed extra appendages which it uses to dig plants out of the ground. It also has a long tongue that it will use to collect plants it has dug out. There are two variants of tuskow found throughout Illusao. The grassland tuskow [seen here] is raised in the southern regions, particularly the Grasses and the Wastelands. Tundra tuskow are raised primarily in the Poles, as they have long, thick fur to help keep them warm.
Despite being completely domesticated, the tuskow is still a herd beast. Farmers will keep entire herds on their land so that the tuskow continuously breed and keep the numbers up. Tuskow give birth to a single calf, which remains attached to its mother. Though it is typically a peaceful beast, tuskow can be dangerous if aggravated. They are large and strong and their tusks can inflict great damage. Male tuskow are larger than females and may be aggressive around the mating season. Tundra tuskow are a bit larger than the grassland variant, so male tundra tuskow are very large beasts.
