8TH CIRCLE MAGE REBORN

As a powerful 8th circle mage, Henry Morris used his magic for the good of the empire. But when the corrupt king Silver Jackson Edward takes the throne, he beheads Morris on fake treason charges. Moments later, Henry wakes up, but in a new body. Though this body’s owner shares Henry’s name, he is but the lowly, talentless son of a baronet. Set on revenge against the king, Henry enters the treacherous Demon Forest to hone his skills so he can once more wield his powers as an 8th circle mage!
