There is nothing more dangerous than an empty throne.

When a failing emperor shocks his court with the announcement that his natural-born son will inherit his crown, chaos quickly follows. Amidst the ensuing crisis, a young knight and his brothers-in-arms find themselves thrust into a dangerous web of assassinations, intrigue, and secrets that could topple empires. Loyal to the last wishes of their liege, the knights set out on a desperate quest to find the secret heir and bring him back to reclaim his rightful place on the throne. With betrayal lurking around every corner, the young knight and his brothers can never know if they are one step ahead of the emperor's enemies... or already too late.
