Summary: The impoverished, barren Kingdom of Asmoira has long been subservient to the Yrnedell Empire. Too beaten down to fight for independence, the people live in abject misery. An order from the Emperor arrives one winter's evening, pushing Asmoira to its limits. There is no choice but to take a stand.
Castiel, one of the Royal Mages of Asmoira is sent to Fairhaven, the capital city of Yrnedell. His mission is simple - Assassinate Dean Winchester, Emperor of Yrnedell.
