Sigil: the key to power

In the shadows of Valeborne City, where neon lights hide the blood on the streets, power comes with a price. and betrayal is the only truth.

Kaien was raised to be the perfect weapon. Born with the Key of Power Sigil, he can steal or destroy the powers of others with a single touch. The government calls him their strongest agent — the one they send when no one else can finish the job.

His missions are simple:

Hunt. Kill. Erase.

But when the corpses of his enemies begin whispering secrets…

When the last breaths of his targets speak of hidden crimes and lies…

Kaien starts to see the cracks in the world he was sworn to protect.

His team is gone — dead, betrayed, or erased.

And as the Key of Power mark consumes more of him, Kaien will be forced to choose:

Stay the government’s loyal hound…

Or turn against everything he’s ever known, and bring their empire crashing down.In a city where everyone has scars, Kaien’s will be the deepest.
