This region of inland Realmgard is more or less similar to the Canadian Prairies and/or Boreal Forest — shout to Ontario Grade 9 geography, so it follows that the wildlife would be similar. Hence, wolves and deer.

And, hence, the deer’s about to have a bad time.

Not really much to say about this, other than plenty of real-life maps and atlases include these sort of drawings of animals, though they primarily tend to be exotic, outlandish, or outright mythical animals like unicorns and sea monsters.
