The behemoth, already weakened by the witches' combined assault, now faced a dual onslaught. Arpious, with her mastery over forbidden magics, and Elara, with her ethereal prowess, worked in tandem to dismantle the creature from within. Their magical energies, intertwined and potent, surged through the creature's vital organs like a storm unleashed upon the core of a tempest. The behemoth, once an unstoppable force, convulsed in agony as the magical onslaught intensified.
As the witches outside witnessed the behemoth's colossal form collapsing, a seismic thud echoed through the enchanted forest. The ground itself seemed to quiver beneath the weight of the creature's demise. The combined efforts of the witches, both within and without, had brought an end to the monstrous threat that had emerged from the depths below. The victory, though hard-fought, resounded as a testament to the indomitable spirit of the witch city and its formidable defenders.
