Ice Wolves

You decide the best option is trying to take the knife. After all, as soon as you have the knife, you can finish them off. You slip out of the doorway, staying on your stomach to avoid being seen. Somehow, they are oblivious to you. Soon, you are only 5 feet away. Suddenly, the werewolf holding the knife howls, drops it, and runs off, yelping in agony. You have no idea why, nor do you want to. You let out a sigh of relief...and that's when you're seen by the other werewolf. You might be able to reach the knife, but it may be wiser to run back to the room.
