The Sisters of the Blade rule Medalon, with an army of elite Defenders to enforce their oppressive rule and keep bordering nations in check. Overseeing all is First Sister Joyhinia. She lives for politics and power and will let nothing come between her and greatness - even her children. So when R'shiel and her half-brother Tarja are caught on the wrong side of one of their mother's schemes, they are forced to flee the capital. Travelling as exiles they see the full extent of the Sisterhood's oppression, and begin to hear rumour of the lost offspring of the legendary Lorandranek, a demon child who will unite the people and vanquish tyranny forever.
