Winter Wolf
Cold-hearted Pack Hunter
- Habitat. Arctic
- Treasure. None
Winter wolves are horse-size, supernatural predators that prowl frigid wildernesses in deadly packs. With their great size and chilling breath, winter wolves pursue megafauna, arctic travelers, and any other creatures they catch on the tundra.
Winter wolves are more intelligent than natural wolves and can speak. Most are predominantly concerned with their next meal, and while they might converse with other creatures in exchange for food, few concern themselves with long-term bargains or keeping their word unless they have something to gain. Winter wolves often hunt alongside frost giants that indulge them with frequent hunts and reliable meals.
A quote from Koran, Winter Wolf
Snowdrifts, driving hail, and wind fierce enough to strip the hairless skin off your bones—you lot have been through it all. But good news, there’s a town full of warm hearths right over this rise.
You’ll never reach it, but at least your last thoughts will be warm.
