In the hyper-stratified kingdom of Oakhaven, the high-vampire nobility lives in a state of suffocating, decadent luxury within the Obsidian Citadel. The entire empire bows to King Cassian Vane, an ancient monarch of absolute, terrifying power who has become catastrophically bored by his own untouchable dominance. To pacify his frantic political council, the cynical King agrees to an arranged marriage, expecting a shallow puppet who will blindly follow the rigid, venomous decorum of the high court. Instead enters y/n—the sole heir to an ancient, old-money aristocratic bloodline. Armed with ethereal, porcelain beauty, high-maintenance demands, and a cold, calculating defiance, y/n completely refuses to play by the Capitol’s plastic rules. Under the watchful eye of a hyper-efficient lady-in-waiting, a bumbling mortal servant, and a malicious royal jester, a dangerous psychological game ignites. In a court built entirely on elegant lies and hidden graves, the lazy King finally finds a force of genuine rebellion that he cannot simply ignore.
