In a world where magic hides in shadows, House Runcandel stands in plain sight.

Known across the Muggle world as an untouchable dynasty of wealth and power, and across the Wizarding world as one of the oldest and most influential noble houses, the name Runcandel carries weight that bends governments, markets, and the Wizengamot itself.

When Keith Argus Runcandel awakens reborn as the house’s sole heir, the world already knows his name.
What it does not know… is the power quietly awakening within him.

A mysterious Sign-In System, bound to his very existence, grants rewards day by day—silent, invisible, and utterly impossible to trace. In a house that already commands nations and bloodlines, this hidden advantage may be the most dangerous secret of all.

Surrounded by allies who smile too easily, enemies who wait patiently, and ancient oaths that cannot be broken, Keith must grow not just as a wizard—but as a ruler.

Because when a house that already rules the world gains something more…
even fate begins to hesitate.
