Uldra are small fey creatures who live in the arctic wilderness and form a close bond with animals and wildlife that live there. They are defenders and guardians of the creatures of the wilds, and will rise to their defense fiercely if they are threatened.
UIdras are naturally adept in the natural world, and can communicate easily with animal wildlife. They're also close to the spirits of winter and cold, and are capable of inflicting mild frost with their touch (and conducting this through their weapons). They are themselves resistant to cold as well.
Uldras often train as druids, and become very skilled with their animal companions.
