The island nation of Ferranda is the jewel of the Acrarian Kingdom, and its Founder, Aritz a Mata, is revered as a god amongst men. But twenty-five years ago, Aritz was merely a man, a colonizer, an Invader seeking glory and fame in the name of his King and Queen, and Ferranda was a nameless union of indigenous Tribes, reverent of the heightened powers and aptitudes granted to them by their Animal Deities, but sundered by the foreigners claiming their lands to the south.

In the unconquered north, the Stone Tribe has for fifteen years offered a safe haven for the southern Tribes displaced by Aritz's Invaders, whose occupying march north has been ostensibly halted by a dense forest barrier dividing north and south. Among the Stone people lives Sen, an outcast for the circumstances of her birth, preserved in society only by her status as daughter of her Tribe's Chief. Forever relegated to the fringes of society, she is forced to watch as countless of her kin, including her sister and brother, complete their rites of passage into adulthood and accordingly earn their aptitudes by the Deity to whom they share an affinity - the Bear, the Wolf, or the Owl.

Despite this, Sen finds comfort in her life of forced solitude with her close inner circle, but hers is a comfort in days of waning tenuous peace. When Aritz's technologically-advanced forces push north, Sen is thrust into a singular quest to rescue one of her precious few captured in the ensuing struggle. While her goal is earnest - save someone dear to her and prove her worth to her Tribe - her people's goal is far more dire: survival in the face of uncertainty.
