Unleashed Darkness: Lucifer's Terrifying Reign over Earth and Hell

"Snap." With the overwhelming power surging through his hand, Thanos manifested his most powerful attack against the Avengers. A bright light illuminated the skyline – blindingly white – then smoky darkness ensued. However, the unfathomable strength of his snap had unexpected repercussions. The force splintered the gauntlet, letting loose a curling crimson energy which rent the very fabric of the universe, unhinging the barriers between realms. Suddenly, a rift shuddered open like a chilling wound in the sky, unveiling a fiery, infernal world beyond. From the depths of Hell, surfaced the suave yet terrifying form of Lucifer Morningstar, the king of Hell himself. His chilling laughter echoed, hair-raisingly eerie. Lucifer took one sweeping look across the battlefield, his eyes glinting with malevolent glee. A smirk of satisfaction playing on his lips, he raised his hand and, in a horrifying instantaneous surge, the sinister energy snapped the Avengers' resistance away. He then went on to conquer Earth and the Hell realms, enslavering humanity in a manner most abhorrent. Depending on the individual human, some lived horrific lives as pets, some were sold into a terrifying life in servitude, while others met their end, forcibly turned into sinner demons to serve Lucifer's hellish army. Earth and Hell became a vast, scarred kingdom of nightmarish horror, with Lucifer relishing his reign atop his infernal throne. As for the fallen heroes, those who once held the title of 'Avenger,' they were now powerless, trapped in a haunting world of despair with the rest of humanity, their hopes of reversing the atrocities but a fleeting dream. No longer were they Earth's Mightiest Heroes; they were mere specters of their former selves, shadows lurking in the terror of this unholy night. In Lucifer's world, there were no happy endings, no light at the end of the tunnel – only an eternal dark, where every soul was a sinner and Hell was home. This was not the endgame they’d envisioned, it was far beyond – a game where defeat was the only end. And thus, the once vibrant Earth plunged into an age of despair and torment, a constant reminder of the cruel fate bestowed upon it, of a time when heroes failed and vanished into the shadowy abyss, and a ruthless king of Hell reigned supreme as humanity cradled its nightmarish existence.
