Prince Of The Empty Throne

He died as the greatest Archmage of his age. He was reborn as the Demon King's most despised heir—a sickly prince with a shattered magic core. Thrown into the brutal academy of a world that has moved on, Ethan possesses only two things from his past life: a mind honed by centuries of arcane study, and the forbidden art of Synthesis Magic—a logical system to deconstruct and rewrite reality's laws. But his new life is a stolen one. He has unwittingly erased the soul of the original prince, Azrael, a gentle idealist whose dreams died with him. Haunted by this guilt, Ethan must wield his Grimoire not just for power, but for penance. In a world of demonic politics, ancient secrets, and deep-rooted prejudice, he will use the scientific method of a bygone archmage to climb from the bottom, unravel the mystery of his reincarnation, and forge a legacy worth the life it cost.
