Shrouded in mist lies the border town of Grey‑Mist. Ostensibly a bustling trading hub, it is secretly ruled by the Shadow‑Wolf Clan — werewolves masquerading as noble merchants. Whenever the Blood Moon rises, clan members must wage a bitter struggle between their humanity and devouring bestial instincts. Five years ago, a great fire broke out amid clan strife. The human girl Isolde barely escaped with her life, left marked forever by a fire‑scar along her jaw. Convinced her once‑beloved Kaelen, heir to the Shadow‑Wolf Clan, had cast her into ruin, she vanished under a new identity. Returning disguised as a herbal merchant, she burned with bitter hatred, determined to bring the entire Shadow‑Wolf Clan to its knees. Yet on the night of the Blood Moon, she was instantly unmasked while sneaking into the manor. Instead of killing her, Kaelen imprisoned her within Blackstone Manor. Captor and captive stood locked in confrontation; old affection and hatred tore at them both, while the Blood‑Moon curse gnawed relentlessly at Kaelen’s sanity. As the truth gradually came to light, Isolde learned that the supposed betrayal had been a trap laid by a third party. Kaelen had borne all infamy solely to keep her alive. Rebel clansmen and the Wolf‑Hunters’ Sect lurked in wait. A shifting Blood‑Moon amplified the curse, and Isolde’s body began slow assimilation by werewolf blood. At a heavy cost, the two must forge their fateful Second Covenant under the Blood Moon, and make their final choice between hatred and love.
