Mullahs of the True Faith have taken the Ket army on a holy quest to invade Ekbir. With no army protecting Ket, Bissel has invaded, taking Lopolla by storm. Ketites remaining in the country are divided and leaderless. Can Ket be saved? Will anyone try? Or is there no place left for those more loyal to Ket than to the True Faith?
