"Now!" Darian shouted. "Use it on the vortex!"
Wei Lin moved forward, gripping the heartstone with both hands. As she raised it toward the vortex, the Codex's pages ignited, glowing with a fierce, golden light that spread like fire. The heartstone acted as a conduit, channeling the Codex's purifying energy straight into the vortex.
A piercing shriek erupted from the vortex as it fought back, its dark tendrils writhing and twisting in agony. The cultists let out cries of despair, their eyes widening with horror as their precious source of power began to unravel.
But the vortex wasn't giving up easily. With a final, desperate surge, it sent a shockwave through the cavern, knocking everyone off their feet. Wei Lin held on to the heartstone, anchoring herself as the energy intensified around her. The Codex flared, sending a beam of pure light into the vortex, piercing it to its core.
