The battle raged fiercely, shadows clawing at their bodies like living nightmares. Riven swung his amulet, releasing bursts of radiant light that seared through the creatures. Lysara chanted incantations, weaving protective shields around them, while Kael's sword flashed like lightning, cutting down foes with precision.
Amidst the chaos, Riven caught sight of a towering figure emerging from the deepest shadows — a being draped in tattered robes, eyes glowing an unnatural crimson.
"The Warden," Lysara whispered urgently. "He's the keeper of the seal... and its guardian."
The Warden raised a skeletal hand, summoning tendrils of darkness that whipped toward the trio. Riven felt the amulet burn hotter in his palm, its power awakening fully.
"This ends now," Riven declared, stepping forward. Channeling the light within the amulet, he unleashed a blinding beam that struck the Warden square in the chest. The creature staggered, its form flickering.
Kael and Lysara seized the moment, pressing the attack. Together, they pushed the Warden back toward the runes that lined the cavern walls.
Suddenly, the runes flared with brilliant light, and a deep voice echoed through the chamber: "Only the pure of heart may restore the seal."
Riven's gaze met Lysara's. "We have to be worthy."
With resolve hardening their hearts, they prepared for the ultimate test — to repair the ancient seal before the shadows consumed everything.
