The servant of Thane lunged, their movements a blur in the dim light. Kai parried, the blade singing as it met the servant's dark energy. Sparks flew, illuminating the cavern walls, revealing the servant's twisted features, their eyes burning with hatred.
Isla, her amulet pulsing, stepped beside Kai. She felt a surge of Elara's power, a protective barrier against the servant's attacks.
The servant snarled, their attacks growing more ferocious. They moved with a speed that defied human limitations, their strikes aimed to incapacitate, to kill.
Kai's blade, forged in the heart of the forge, shimmered with pure light, cutting through the servant's dark energy. Each strike pushed back the shadows, revealing the servant's weakening form.
Isla, channeling Elara's magic, focused her energy on the servant's connection to Thane. She felt a faint thread, a link between the servant and the dark power that flowed through them.
With a focused burst of energy, she severed the link. The servant cried out in pain, their form flickering, their eyes losing their malevolent glow.
Kai seized the opportunity, his blade striking with precision. The servant's form dissolved into a cloud of dark smoke, their chilling whispers fading into the silence.
The darkness receded, the air clearing. Isla and Kai stood side by side, their breaths ragged, their bodies tense. They had defeated the servant of Thane, but they knew this was just the beginning.
