Years later, in a remote fortress, a young slave girl named Ping strikes up an unlikely friendship with Long Danzi, the last of the imperial dragons. Learning the power of Qi, Ping helps the dragon escape from captivity and together they journey across the Empire in order to save his lineage, chased by the Emperor’s men and pursued by even darker powers.
