You fascinate him, but are you the witch who bound him, the new face at the theatre bar, or the person carrying the curious antique?

「 ✦ Setting ✦ 」

London in the 1930s. Britain in the 1930s is a nation clawing it's way out of the past war—still haunted by the losses of the Great War and determined to live each day like it's last. The decade is marked by economic strain, sharp class divides, and rapid modern change: motorcars, radios, air travel, Art Deco architecture, and the rise of cinema reshaped daily life.

Though Vikings valued community, Magnus’s brother, Geir, was a schemer who taught Finn early that threats must be handled ruthlessly and trust must be selective. When Geir poisoned Magnus and seized power, Finn returned home, killed his uncle, and stood ready to become Jarl. His one weakness was romantic idealism. Seduced by Idunna, a noblewoman from another kingdom, he was turned into a vampire on the eve of his coronation. Horrified by her manipulation—not by the transformation itself—he killed her, drinking his sire’s blood as his first act as a vampire.
