In a world of magic and monsters, I carved out my own empire. Hellfire Studios - my brainchild, my legacy.It all started with “The Demonfather” - a blatant copy from my past life, sure, but this world had never seen anything like it. Humans, elves, dwarves - they all fell in love with it. Critics raved, audiences cheered, and suddenly, I was on top.But the world thought I was a one-hit wonder. They had no idea what was coming.I unleashed “The Lord of the Rings” upon them. The result? Critics were left speechless, fumbling for words to describe what they'd witnessedBut why stop at movies? This world was stuck in the past, so I dragged it into the future. I created computers, birthed video games, and watched as everyone from imps to elf elders became addicted to pixels and polygons.Still not satisfied, I turned to music. I crafted stars, produced hits, and soon had the entire realm dancing to my tunes.But even that wasn't enough. Comics, manga, cartoons, anime, novels - I introduced them all. I flooded this world with stories and art forms they'd never dreamed of.Before long, people weren't just consuming my creations - they begun worshipping me. They started calling me “The Lord of Entertainment.”
