Reborn as a Weakest Prince

After dying from betrayal in his previous life, a brilliant but ruthless military strategist reincarnates as Kael Vaelorian—the weakest and most hated prince of the Astraviel Kingdom. Mocked for lacking magical talent and targeted by his royal siblings, Kael is expected to die quietly. Instead, he discovers an ancient forbidden magic system tied to lost runes and forgotten kings. Using intelligence, manipulation, and overwhelming ambition, Kael begins transforming his ruined territory into a military powerhouse. While building armies, defeating monsters, and crushing corrupt nobles, he slowly gathers loyal companions—and dangerous enemies. But the closer he gets to the throne, the more the kingdom fears the monster he is becoming.
