The Eye of the Bedlam Bride: Dungeon Crawler Carl, Book 6

Fantasy. LitRPG. A pantheon of forgotten gods. An old grudge between a talk show host, an heiress, and the man they shattered along the way. A rapidly deteriorating AI system. An inconvenient tiara upon the head of a friend. It is bedlam on the eighth floor. As management reels from the unexpected conclusion of the seventh level, the surviving crawlers stumble onto the eighth and find themselves scattered. It's a map based on Earth's final days before the collapse, where ethereal, intangible ghosts of humanity go about their lives, oblivious of the impending doom. Living amongst these ghosts are monsters based in Earth lore. “Legendary” creatures tied to the geographical location they inhabit. Each team of crawlers is given a task: find and capture six of these beasts. The captured monsters will be turned into cards. Cards that can be summoned into battle again and again. The stronger, the deadlier, the better.
