The Shagrat is a marmot that is the size of a sheep. It feeds on the European ice sheets and can survive in temperatures as low as -60.

The shagrat is a giant rodent that inhabits the northern European tundra. The shagrat is descended from marmots, which today inhabit harsh tundra-like regions in mountains. The shagrat stands 3 feet (0.91 m) tall and is built similarly to mammoths and musk-oxen. They most closely resemble the capybara of the present-day Amazon rainforest. It has short legs, short tail, and other small extremities. Its body is covered with two types of hair: woolly underfur and hollow, air-filled guard hairs. Those and a layer of fat beneath the skin protect it from the cold. Shagrats wander in herds, feeding on shrubs and grass. It fears the deadly snowstalker, which brings down weak shagrats with its dagger-like saber-teeth. Its only defense is staying with its herd, which will form a defensive circle similar to that of a musk ox herd. These large rodents migrate south every winter, but they are followed every step of the way by snowstalkers.
