Deer

Deer biggest and most powerful of horned animals but still weak in compare to fiends, they are wild animals with iconic big antlers overruning Northern Kingdoms and Isles at least, with such animals as roe deers, wild goats, wild boars and wild horses and they are naturall food for wolves, bears etcetera.

Adapted to cold enviroments there is no problem for them to live further north you go, maybe core Nilfgaard is a problem to them and they likely extinct or never lived here. Classic food for them is grass.

They are one of those atmospheric creatures that are not concected to and quest or contract, simply runing through Kaer Morhen valley, White Orchard, Gustfields, Velen and Skellige Islands.
