Quick answer: 8 episodes, English original audio, and episodes 1–8 play right here tonight.

Crown Princess Astrid is poisoned by her fiancé Erik and her closest confidant Silas on the eve of her coronation. Her soul bargains with the Norns, trading her human warmth for black magic and a second chance. Resurrected in the frozen north, she allies with Ragnar—the late king's illegitimate son and a savage warlord. She supplies strategy and sorcery; he supplies muscle and army.

Disguised as a priestess, Astrid infiltrates the capital, using mind-reading and desire magic to drive Erik to public madness, turn Silas against himself, and make the love-obsessed Linnea raise the Mirror of Truth before the kingdom. Every spell drains her life and triggers an ice curse; only Ragnar's searing body heat can pull her back, forcing intimacy that ignites a taboo love. At the coronation, the Mirror exposes Erik and Silas's treason and murder. In the final battle, Astrid freezes herself to shatter the royal array. Ragnar cuts open his chest, pouring burning blood over her to melt the curse. They are crowned together, founding a dark empire of vengeance, fire, and an unbreakable bond.
