The Guardian was moving fast regardless of its gigantic size, and its mighty fist landed where Anita had been standing. She turned to her side just in time, and the ground exploded just beside her.

“It’s not just a creature,” the redhead yelled, barely managing to avoid the attack. “It’s the forest itself. We’re fighting its will.”
