Atheria - the fabled city of songs and the shining jewel of the third sea. Here, the masked exultia caste hold sway and vie to outdo each other in their patronage of the arts, sometimes with deadly consequences. Guyime is now a wandering, dethroned King of the Northlands, and he is drawn to Atheria by his quest for the Seven Swords, the demon cursed blades of legend. But to claim the next sword, he must first solve a seemingly impossible murder - a puzzle that once untangled will unveil secrets so dark they could bring the City of Songs to utter ruin.
