Young Erasmus Cromwell-Smith II's adventure happens inside Prague's astrological clock. Together with a band of five other harlequin-dressed youngsters, he experiences a city filled with wizards, enchanters, witches, conjurers, and evil gargoyles. The youngsters seek clues to reach the mysterious Hradcany Castle and become Wizard Apprentices. They are guided on their quest by The Orloj, the old clock, and Buggie and Thumpee, his sons. Through the wicked streets of Prague, the six harlequins must find six statues representing each of the human virtues of Generosity, Humility, Compassion, and the human flaws of Pride, Envy, and Avarice. They earn clues to reach the castle only after they successfully learn them. The Orloj is a magical tale filled with non-stop action, thrills, and timeless wisdom through nine timeless fables and poems.
