Kai Sera is the greatest asset of war that exists. In a world where most mages only have the ability to wield one element, she wields them all: fire, earth, water, air, life, and death. Though she is raised as royalty by an adoptive father at the prestigious Seran University of Magic, he refuses to put her skills to use in his army, so Kai breaks free of her bonds to go on a quest of adventure and self discovery. One simple quest will turn into a life-changing phenomenon for Kai and her companions. Beliefs are challenged. Old secrets are unearthed. Legal lines are crossed. Loyalties are divided. The seeds of rebellion are planted. When it comes time for Kai to face the truth, a legend will be born.

In Kai Sera's rage after the brutal execution of a loved one, she has decimated one of the most prized cities in Chairel in a show of magical prowess, and now the country seeks her head. Kai and her companions flee to the unfamiliar land of Nahara, where she must convince its leaders to ally with her in a rising rebellion against her former home. Nahara is a strange and dangerous land full of giant beasts, and it has a culture that values the bloodshed of gladiators in its coliseum. If any country will join Kai in waging a war with political goals that include legalizing necromancy, it is Nahara. But convincing them may not be easy—for Kai must first prove her power against foes who have yet to be defeated, and when it comes time to battle with Chairel, her ideals will force her to oppose those she loves.

The War of Necromancers has begun. After her first victory in battle against her former home, Kai Sera and the Seran Renegades are now a force to be reckoned with. They plan to garner support from far away lands, and set off across the ocean in search of more allies. Word of Kai's identity and her actions in Nahara have spread across the world, however. The gods are on her trail and angry with her transgressions, and their powers equal hers in strength. The Seran Renegades are thrown vastly off course, and must quickly rethink their plans. A chance encounter with an audacious man with his own desire for vengeance gives them a new goal which will aid them in their war. They build an army of erratic soldiers in a forgotten land in preparation of Kai's first offensive war campaign: taking over the assassin-infested underground.
