Legendary

All the creatures of historical myths, legends and lore really do exist for real, they've just been locked away in Pandora's Box for thousands of years, just waiting to come out again.... When a thief named Deckard is tasked with stealing an ancient work of art, he unwittingly triggers a war between man and myth. Bird gryphons rule the skies, werewolves maul the innocent and cities are under siege, while creatures we dismissed as figments of our ancestors turn out to be true and very angry at having been imprisoned for untold years. Deckard is the only person who can transport these creatures back into the box, and he finds that he must work with a shadowy secret organization to save civilization before it is torn apart by teeth and claws.
