Reincarnated As The Duke's Son in an magical empire

He was not reborn to struggle. He was reborn to conquer. When Leo, a pragmatic engineer, dies, he awakens not in an afterlife, but in the cradle of Kaelan Silarion, the firstborn son and heir of the mighty Duke Valerius in the empire of Elyssiara. This is a world of blade-based magic and terrifying mythical beasts, and unlike other reincarnated souls, Kaelan is not weak. He is a prodigy. Born with a perfectly attuned body and a vast, innate reservoir of magical power, Kaelan's only challenge is controlling the devastating Aether-Weaving magic that threatens to overwhelm him. Guided by his adult intellect and analytical mind, he sees the magic not as a mystery, but as a system of energy to be understood and mastered. His birth sends ripples through the empire. His father, the formidable "Iron Duke," sees in his son not a disappointment, but a weapon to be honed. His mother, a powerful mage, sees a destiny that must be carefully guided. And the empire's shadowy players see a threat that must be eliminated before he reaches his potential. Kaelan's journey is not one of gaining strength, but of mastering it. He forges his first Aether-Blade not as a teenager, but as a child, its resonance shaking the foundations of the ducal manor. He doesn't stumble upon a wounded beast; he ventures into the deepest Aether-wood and claims a legendary Storm Monarch as his bonded companion through sheer force of will and power, a feat never before accomplished. But power attracts challenges. Rival noble houses, terrified of the Silarions' newfound advantage, move from political subterfuge to open assassination attempts. An ancient order, guardians of the world's balance, see his unnatural growth as a blight that must be purged. Kaelan must quickly learn that in Elyssiara, a sword is not enough. He must master the battlefield of the imperial court, where a whispered rumor can be deadlier than any mythical beast. With the might of a duke's army at his back, the loyalty of a legendary beast, and the unyielding power of a prodigy, Kaelan must carve his legacy. He will not hide his strength. He will use it to shatter conspiracies, defend his house, and ascend to a height that will redefine the very meaning of power in Elyssiara. The Scion has arrived.
