The Solvaris Empire is surrounded by the Godspire — a massive wall a thousand meters high, older than anyone can remember, and deadly to cross. No one knows if it was built to protect the Empire… or to trap it.Reth, a 19-year-old from Earth, finds himself in this strange world. He has no great strength or magic, but a unique Obedience System forces him to serve Princess Asthia, the sharp and ruthless commander of the Serpent Wing.If he disobeys her, he suffers unbearable pain — maybe even death. If he obeys, he gains new powers and skills, growing stronger with every command.While the Empire’s Obedience Sigils keep its people in chains, Reth’s System makes him something different — a weapon, and Asthia’s personal bodyguard.Together, they face plotting nobles, rebel cults dreaming of life beyond the wall, and monsters twisted by corrupted mana.But as Reth’s Corrupted Intent — a cold, unshakable will — grows, so does his resistance to Asthia’s control. Their uneasy trust is tested when they uncover a secret about the Godspire’s true purpose.To protect Asthia and reveal the truth, Reth must decide whether to keep obeying… or risk awakening a horror that could destroy them both.
