For 1,000 years, the Guardians have protected Havenshire from all evil. Then, the Dark One came. After an epic battle, the king and most of the Guardians lie dead. The few surviving Guardians flee with the young prince to Riverway.
From Riverway, the Guardians frantically search for the fabled city of Haven. Haven may hold the key to finally defeating the Dark One.
The Dark One nears Riverway. While the people rush to build defenses, the Guardians race to find Haven.
Will Riverway withstand the Dark One's onslaught? Can the Guardians reach Haven in time to save Riverway? Or will their failure mark the Fall of Havenshire and the end of the Guardians.
