In 'Chrono Chums: Who's There?', players assume the role of a quirky historian named Molly, who stumbles upon a lost journal containing fragmented time-traveling spells. After accidentally activating the powerful tome during a mundane book club meeting, Molly finds herself jumping through different historical events, each filled with humor and danger. As she meets a cast of eccentric characters—like a snarky knight from Medieval times and a rebellious flapper from the Jazz Age—the players must navigate relationships, solve cryptic puzzles about their pasts, and make choices that will alter history itself. With every decision, the timeline shifts, creating a dynamic narrative where humor clashes with dramatic stakes.
