Much of Vostheloren's history is lost. The formerly united realms of men, elves, and dwarves have retreated to separate corners of the world, deeply suspicious of one another. Most remember only war, fear, and a darkness, known as the "horizon of storms," that bloomed across the seas. Thousands of years have passed since the shadow first appeared, but now the evil, once thought vanquished, lies in wait, threatening to destroy all who challenge it.

Tagwen Braithe, newly ascended queen of Yeacralas, the southern realm of men, has taken up the throne after the death of her father. She knows little of her world's tumultuous past and even less about how to fill her father's shoes. Many consider her title unearned, so when she answers an urgent call from a neighboring kingdom, she considers it her chance to prove her mettle to the people she is sworn to protect. But as she discovers, her journey will be the beginning of the world's darkening end and she will be forced to embark on an odyssey that will take her beyond the call of duty and reveal her true destiny.
