The witch queens of Irrisen must abdicate their thrones every 100 years when their mother, Baba Yaga, places a new daughter on the throne. But one queen was unwilling to relinquish her rule, and led a doomed rebellion against the Mother of Witches. Afterward, Baba Yaga entombed her wayward daughter in an icy necropolis known as the Veil of Frozen Tears, along with a powerful artifact called the Torc of Kostchtchie, hiding them both far from mortal eyes. Now, almost 500 years later, the tomb has been found, and the race is on to plunder its treasures.
