The energy around Black Castle is now too chaotic, and the Giant of Perilous Mountain could explode at any moment.
Kimberly's approach involved sustaining a stable energy channel that allowed the undead spirits of the Giant of Perilous Mountain to home in on Isabella. Then, she would lead them away from Black Castle.
It turned out that Kimberly's approach had no problems.
The Giant of Perilous Mountain, despite its considerable size, was after all just undead and because its body contained fragments of other spirits, it had no thinking ability. Its sole logic of behavior was to find living people and then explode.
Now, the only living person's aura it could sense, under Kimberly's arrangement, was Isabella's alone, so naturally it followed Isabella's footsteps towards the wilderness.
