The evil Hacker's plot to destroy time continues. As soon as the Adventurers arrive in Misenum they meet a young boy, Gaius (Pliny the Younger - the author who described the eruption of Mount Vesuvius). The teens and Gaius are arrested by two centurions (really The Hacker's two evil Agents) and brought to the Gladiators' arena in Pompeii. A female gladiator, Edwina, helps them to escape and get back to Misenum just in time to save themselves and escape the historical eruption.
