**Chapter 2: The Cube of Pure Darkness**
The Abyssal Lord raised a hand, catching the Shadow Bolt in his palm and crushing it into nothing. He combined the essence of his Fireball with his dragon's void energy, forging a new, terrifying spell. A sphere of swirling black flames and cosmic power materialized before him—a Void Dark Matter Ball.
With a flick of his wrist, he unleashed it. The orb warped the air as it flew, incinerating the Shadow Hydra and shattering Zorak's renewed barrier. The shockwave sent the summoner skidding across the arena floor.
Desperate, Zorak summoned his ultimate creature: a Shadow Behemoth, a hulking monster of darkness with glowing red cracks across its body. As it charged the Void Dragon, Zorak cast a Shadow Mirage, creating illusory copies of himself to confuse his opponent.
The Abyssal Lord felt a sudden drain. His newfound power was immense, but sharing his vitality with the colossal Void Dragon was taking its toll. He dropped to one knee, his strength faltering.
"I'll not back down!" he shouted, his voice echoing with newfound authority. He commanded his dragon, now more a part of him than a mere summon, to use a weakened Galactic Black Hole Energy Beam. A spiraling beam of void energy erupted from the dragon's maw, striking the Behemoth and halting its charge, though the monster remained standing, enraged. The beam also dissolved two of Zorak's illusions.
Zorak saw his chance. He commanded the Behemoth to unleash a Shadow Shockwave while simultaneously sending a Shadow Leech tendril snaking towards the weakened Abyssal Lord, aiming to drain his remaining vitality.
Sitting helplessly, the Abyssal Lord reached into a pocket and pulled out a small, unassuming object: a Cube of Pure Darkness. Its surface was so perfectly black it seemed to absorb all light, a hole in reality itself. "I need to use this," he whispered, activating it.
An incomprehensible aura radiated from him. An invisible barrier of pure power formed, effortlessly repelling the shockwave and the leech. His vitality began to regenerate at an impossible pace. He rose to his feet, his power fully restored, his white eyes glowing from beneath his dark hood.
With a casual raise of his finger, he destroyed the Behemoth. He destroyed Zorak's remaining illusions. He destroyed every summon on the field, leaving only Zorak, alone and defeated.
