"What Gods Demand" was published in the anthology Blackguards: Tales of
Assassins, Mercenaries, and Rogues.
About this story, author James A. Moore says, "The Empire of Fellein has
reigned in relative peace for hundreds of years. The legends told by the
people speak of a first empire and the greatest city ever known to
mankind, Korwa. According to the tales, Korwa was destroyed in the
distant past in an epic battle so intense that it destroyed part of the
world and created the Blasted Lands. There might be some truth to the
legends. Not long ago, explorers from Fellein found the distant Seven
Forges mountain range deep in the Blasted Lands, and also discovered, to
their surprise, that the area within that range is inhabited by people
called the Sa'ba Taalor. The gray-skinned people from the distant realm
have come to Fellein. Since that moment, a war has been building. Swech
is one of the Sa'ba Taalor, chosen by her gods to hide among the humans
and do the will of her deities."
