She uses her wiles to survive, but eventually, she is captured and sold into slavery in the kingdom of the Holstein, a master race of bovine. Kyra is treated well by her new masters, and she earns the respect of her Master, Prince Meateus, when she shows her abilities. Prince Meateus leads an expedition across lands unknown to the bovine, in order to find the Lost Cities of the race of humans. However, there is one among them who would see the Prince meet up with an accident, and the expedition fail.

After finally learning the fate of the forbidden weapons they learn their troubles are not over.
