From Lexicanum

Wolf Priests take the roles of the Chaplain and Apothecary within the Space Wolf chapter, being responsible for both the spiritual and physical well-being of their fellows¹. They are selected from any part of the chapter but usually from the Long Fangs or Wolf Guard due to the greater wisdom of these marines. Instead of using codex medical equipment, Wolf Priests using healing potions and balms, using knowledge passed down from one Wolf Priest to the next.

Wolf Priests are also almost entirely responsible for the recruitment of aspirants to the chapter, selecting them from the hardy native warriors of Fenris. Commonly garbed with wolf totems, including wolf-skull shaped helmets, they can often be seen observing battles from nearby vantage points, ready to select suitable candidates for the Space Wolves from the survivors.¹
