It wasn't long before the trucks that the Academy had sent arrived to pick up the materials from the defeated pack of Dire Wolves. While they weren't elemental beasts whose parts could be used as reagents for Elemental spells, they were magical beasts with substantial power.
So, every part of them, even the fur, could be used as a focus to aid Nature Magic, most of which was Witch Magic. A bit of the magic-infused fur would be enough to help focus their spells when built into an amulet or wand, and that would allow them to cast both more quickly and more precisely.
For things like healing spells and plant growth charms, both of those effects were incredibly important. The Academy normally couldn't supply something like a bit of fur from a Rank Two Dire Wolf, though. It wasn't within their means to easily hunt, and there shouldn't have been any here to hunt to begin with.
