Rhea, the trueborn daughter abandoned by her birth mother in the Abyss Blood Arena at a young age, returns to Silverkeep. She slays the fake daughter who framed her on the spot and assembles a female guard battalion with ruthless tactics. Mira, heir to the Nightspine Royal Family, forms a blood pact with her and enlists her help in seizing the throne. Rhea takes command of military forces, pacifies the borderlands, survives the Moon Goddess Trial to awaken her ancient bloodline, kills the birth mother who abandoned her, assists Mira in ascending the throne, breaks the millennium-old military code, and becomes the female commander ruling over the four realms.
