After the judgment, the ire of God was revealed with the words: “Be cast unto eternal damnation!” And so it was that humans and jinns alike found themselves scattered across the Nine Circles of Hell, left to burn and suffer for eternity. Until after an untold number of eternities, an angelic voice called out, announcing God's decree: “One soul shall earn the chance to return to grace.” Humans and jinns found a shimmering screen appear before their eyes, tallying their sins and something called 'Fragments of Divinity'. “Cleanse away your sins,” said the voice. “Do what must be done!”Now, a human known as Wretched Nameless One—the only human found in the Ninth Circle—sets out on a journey to claim his spot in Heaven, tasked with fighting hellish monsters and devilish hell-dwellers competing to return to grace. Will he escape eternal torment and rise to grace or return to the everlasting cleansing fire once more?
