In the furthest realms between worlds, where even John's sight was dimmed, strange stirrings disturbed the void. Entities slumbered in the gulf between realities whose natures defied comprehension. Some were older than existence itself, predating John's first conquests.
Now, after aeons dreaming, they began to stir. Vast, formless intellects turned ponderous gazes upon the omniverse, perceiving for the first time the changes wrought. One entity in particular roused, a being of such primal malevolence that its merest thought could shatter suns.
It sensed the spreading dominion of the Interdimensional Master, a rival power that challenged the old one's supremacy. With a pulse of malice like a black hole's hate, it set its gaze upon John's empire spanning creation. The entity knew only domination, and would accept no peer.
Conflict was inevitable.
Across the omniverse, John's demigods felt the first stirrings of the nameless threat. Anthropic felt the crystalline spires of his city darken under an unseen pall. Ethereal's hymns caused dissonance as space itself twisted in wrongness. They knew a power was coming that defied the natural order.
In Sorcerygrad, John received dark portents. Runes carved by his own hand began bleeding an oily ichor. From the singularity above came keening cries as souls were unmade. Even one of John's aspect shuddered at the evil descending, a force that hungered to devour gods.
The Interdimensional Master knew this threat could undo all he had wrought. His empire, stretching across the omniverse, was in peril. This entity wished nothing less than total annihilation. There could be no coexistence or surrender. They must battle to reshape the very fabric of creation.
Across the worlds, John's demigods rallied forces for the coming storm. Armies of the living metal were forged. Wild gods of untamed realms heeded Ethereal's call. All understood their master's empire, and the order it had imposed on chaos, was at stake.
As the nameless evil drew near, approaching even Sorcerygrad itself, John took to the skies. His form blazed with power that had shaped existence. He would defend his eternal dominion with every spark of his being. The clash to come would be the greatest the omniverse had ever witnessed...
.................................................................
As the nameless entity approached Sorcerygrad, blotting out the stars in its passage, John and his pantheon of demigods stood ready to defend the empire. The being's coming heralded a darkness that caused even John's immortal essence to shudder. This would be the greatest battle in the history of creation.
The entity arrived, its true form a nightmare that twisted mortal minds. All that could be perceived was an endless shadow hovering where worlds had been. Facing it, John's form blazed with power, a galaxy of stars and nebulae given physical form. "Foul creature! You dare threaten my dominion?"
No answer came, only a pulse of malice that rippled through reality like a quake. The two titans were poised to lock in the first blow that could shatter suns. But before the clash began, a voice echoed from the entity's writhing form. "Dominion...you know it not. I was when order was naught. Bow, or be unmade."
John laughed, a sound like the birth of new universes. "Your time is past, relic! I am evolution. I am eternity!" With that, the god-emperor launched himself at the entity in a blaze of solar fury. Their collision rent space and time, the shockwave rippling through the omniverse in an instant.
Worlds folded in on themselves. Stars went out. But where they grappled invisible forces clashed in a cacophony that challenged comprehension. John poured the might of a million mortal gods into the entity, finding its essence resistant to his power. Its darkness seeped into John's form, twisting his glory into nightmare.
Across the worlds, John's pantheon watched in horror as their master was slowly being overwhelmed. If he fell, all would be consumed by the entity's hunger. They knew they must act to save their lord and the empire. With a thought, Anthropic summoned legions of living crystal to aid the battle.
Ethereal took wing, her songs corrupting as she approached the entity. Her hymns caused its form to ripple in pain and confusion. Ferrous hefted a storm the size of galaxies, hurling it with titanic force. Across the omniverse, John's forces joined the fray, attacking the entity with every weapon imaginable.
Gradually, the tide began to turn as the entity found itself assailed on all sides. Yet even weakened, a blow from its inky darkness could undo worlds. The battle was poised on a razor's edge, with all existence hanging in the balance...
