The air in the war camp grew thick with tension as the Black Knight's laughter echoed through the tent. His sword, Kilineiram, pulsed with a deep crimson light, emanating a malevolent aura that sent shivers down the spines of the warriors present.
Riku, still seated and wounded from the battle against the Demon God, narrowed his eyes. His instincts screamed danger.
"Something is wrong..."
The Black Knight's stance shifted unnaturally. His body jerked, his fingers tightening around the hilt of his sword. The glow in his eyes flickered, as if something else lurked beneath.
Then, without warning, he lunged.

The Battle Begins
"[Greater Teleportation]!"
Rigrit, the magic caster and one of the strongest members of the 13 Heroes, reacted instantly. With a flick of her staff, Riku disappeared in a flash of light, reappearing at the far end of the tent.
But the possessed Black Knight did not hesitate.
"[Greater Break Item]!"
A pulse of dark energy exploded from Kilineiram. The protective magical artifacts around Riku shattered into pieces, their protective enchantments dissolving into nothingness.
Riku gritted his teeth. "Damn it...!"
The warriors around the camp snapped into action.
"He's possessed! Take him down before he kills Riku!" one of them shouted.
The Black Knight—or rather, Kilineiram—grinned.
"[Dark Blade: Vorpal Strike]!"
With a single slash, a wave of crimson energy erupted from the sword, slicing through the battlefield. The wave cleaved through the ground, sending debris and warriors flying. One unfortunate fighter was cut in half instantly, his blood spraying onto the dirt.

Riku's Final Stand
Riku, despite his injuries, raised his greatsword. His eyes locked onto the Black Knight, who was advancing on him like an executioner.
"If you're truly possessed, then I'll just have to sever the connection!"
He lunged forward, his blade shining with divine power.
"[Holy Smite]!"
His sword clashed against Kilineiram in a blinding explosion of holy and dark energy. The impact sent shockwaves rippling through the battlefield, forcing even the strongest warriors to brace themselves.
But Kilineiram was ready.
"[Mana Drain]!"
A dark mist erupted from the sword, latching onto Riku and siphoning his remaining magical energy. His strength faltered. His arms trembled.
"You were supposed to die in the original timeline anyway, Riku," Kilineiram whispered mockingly in his mind. "Consider this destiny."
Riku's eyes widened in horror.
"[Dark Possession: Soul Rend]!"
The Black Knight plunged Kilineiram straight into Riku's chest.
A deafening silence fell over the battlefield.

The Aftermath
Riku gasped, blood spilling from his mouth. His vision blurred as he stared at the Black Knight—no, at the entity inside him.
The sword pulsed.
Riku's body began to wither, his soul being devoured. His once-powerful aura faded into nothingness.
Rigrit, seeing the inevitable, gritted her teeth. "Damn it all... We have no choice!"
"[Sealing Magic: Chains of Eternity]!"
From the heavens, spectral chains shot down, wrapping around Kilineiram and the Black Knight's body.
The possessed knight snarled, trying to move, but the chains burned his very essence.
"You think you can stop me?!" Kilineiram roared.
Evileye followed up, chanting rapidly
"[Absolute Seal]!"
A massive runic circle formed beneath them, glowing with an ancient script. The air twisted, space itself warping around the possessed knight.
The warriors of the 13 Heroes, even in their grief, joined together, pouring their remaining magic into the sealing spell.
Kilineiram screamed in rage as the darkness around him was suppressed. The Black Knight's body crumbled, but the sword—Kilneiram—remained, glowing ominously as it was dragged into the magical abyss.
With one final pulse of power, the spell activated fully.
The battlefield fell into silence.

A Cursed Blade in the Darkness
Deep within a forgotten cave, far from civilization, the sword Kilineiram lay buried beneath countless chains, glowing faintly in the darkness.
The whispers of its sealed power echoed faintly, waiting for the day someone foolish enough would break the chains and unleash its full might once more.
