Man-made isekai
"An extraordinary genius scientist betrayed by his only friend and killed was Reborn As an illegitimate child, raised in shadows, and mocked as worthless-Williams carries no desire for titles, crowns, or kingdoms. But when the Coming of Age Ceremony shatters every expectation, the 'useless prince' reveals a power that shakes the very foundations of Dragonage. In a land ruled by strength, where betrayal brews in noble halls and family hides sharper blades than enemies, Williams must carve his own path. Not as a prince... but as something far greater."
