Diabolic

Nemesis is a Diabolic, a humanoid teenager created to protect a galactic senator's daughter, Sidonia. The two have grown up side by side but are in no way sisters. Nemesis is expected to give her life for Sidonia, and she would do so gladly. She would also take as many lives as necessary to keep Sidonia safe. When the power-mad emperor learns Sidonia's father is participating in a rebellion, he summons Sidonia to the Galactic court. She is to serve as a hostage. Now there is only one way for Nemesis to protect Sidonia. She must become her.

It's a new day in the Empire. Tyrus has ascended to the throne with Nemesis by his side, and now they can find a new way forward - one where they don't have to hide or scheme or kill. One where creatures like Nemesis will be given worth and recognition, where science and information can be shared with everyone and not just the elite.

Three years ago, Tyrus Domitrian shocked the galaxy by killing the woman he swore to love forever. The woman for whom he upended the Empire. Now, the once-idealistic heir apparent has become the cruel Emperor Tyrus, wielding his authority with an iron fist, capable of destroying planets with a single word, controlling all technology with a simple thought. He has bent the Grandiloquy to their knees, and none have the power to stand against him. But there is a muttering among the Excess. They say that Nemesis is not truly gone.
