The world turned as it always did, caught in the familiar ebb and flow of life. People rushed through subway stations, children chatted animatedly on their way to school, and workers crammed onto buses for their daily commute. It was an ordinary day, much like any other, with humanity oblivious to the impending cataclysm that would soon shatter their existence.
But then, as though the very fabric of reality had frayed, the clouds overhead began to writhe and distort. The serene blue of the sky transformed into a swirling maelstrom of ominous gray and black. An air of foreboding swept through the streets as people pointed upwards, their faces etched with disbelief and fear.
The transformation of the sky was a harbinger of something far more sinister. Colossal portals emerged, seemingly tearing through the very fabric of space itself. They hung suspended in the heavens like ominous gateways to an unknown realm, leaving the denizens of Earth gaping in awe and dread.
