The besieged Imperial City lies inside the massive wall of the Armitage; outside, the attacking Mor have laid waste to most of the land. The Imperial Court seems unaware of their peril, but Kirin and Lia - who have barely survived the Mor and made their way to the City - know the danger all too well! When Kirin discovers a necromancer who seems to possess her power over blood, she hopes he can help her understand her strange magic. Meanwhile, the deadly Mor are assaulting the walls of the city that shelters them.
