In 'Chrono Chums: Who's There?', players assume the role of a time-traveling historian trapped in the sprawling Library of Anachronism, a magical repository housing characters from different timelines and dimensions. As you navigate through different literary periods, you encounter iconic figures—like a snarky Shakespeare, a brooding detective from Victorian London, and a futuristic rogue AI—all vying for your attention and assistance. Your decisions shape the narrative as you solve puzzles, forge alliances, and engage in dialogue that reveals both humor and drama. As time blurs, the historian must uncover a hidden conspiracy that threatens the fabric of reality itself, all while racing against other time travelers to prevent catastrophic changes to the timeline.
