Grunhilda curses wildly under her bad breath. Damn wolves arrive just as she finds the mechanism! The wolves will smell her when they arrive and sound the alert, or hunt her down.
She seriously considers just opening the secret door and exploring alone. She would have surprise, and the wolves would be locked out...but who knows what lurks in the hillside.
Hmm...
Grunhilda suddenly turns and rushes to back the small hillocks and hide in the brush, axes ready to cut down any wolves who rush her. If the goblins let the wolves into their tunnel, she will wait a moment for their secret door to close, then run back to camp. She may not have much speed, but her strong endurance will allow her to run without stopping.
