Large boar covered in thick white fur and blubber, adapted to extreme cold
A Polar Boar is covered in thick mottled white fur and an even thicker layer of fatty blubber. Adults are about 6 feet long and 4 feet high at the shoulder. While quite rare due to the difficulty in domesticating, a polar boar is large enough to be ridden or to pull a sled. They are used by some northern Dwarf clans.
Due to the extremes of its habitat, a polar boar has an even nastier temperament than a regular boar. It will typically charge and gore its opponent with its sharp tusks; females and males are equally dangerous.
