Great Plague

The Great Plague is remembered not only as a period of mass disease but as the origin point of The Fort’s vampire society. During the plague, Viktor bit and transformed his family, converting a human household into an enduring supernatural community whose later life is organized around blood, sunlight, labor, hierarchy, and controlled isolation.

Origin of the Fort’s Vampire Community

The decisive event associated with the Great Plague is Viktor’s mass transformation of his household. He turned his son Valnoir, Magnus, Charlotte, Victoria, Lady Harriet, and Lady Mary into vampires, while Viktor himself became the family’s continuing head. The transformations occurred when the family members were different ages: Valnoir was twenty-four, Magnus twenty-five, Charlotte four, Victoria twenty-nine, and Lady Harriet and Lady Mary were adults whose precise ages are not given. This preserved the family in a supernatural form while fixing their relative ages and relationships across subsequent centuries.

The event also explains why the Fort is simultaneously a family residence and a collective refuge. Viktor’s authority extends beyond private parenthood: he is described as the president, head, and master of the house. The Great Plague therefore marks the shift from an ordinary family structure to a governed vampire settlement, with Viktor’s act of transformation producing both kinship and political responsibility.

Historical Scale and Physical Consequences

The transformation is situated in the eighteenth century, during the Great Plague. Its consequences reach far beyond the original household. By the narrative present, The Fort is an eighteenth-century mansion with more than 500 rooms spread across approximately ten stories; only three stories are above ground, while the remaining levels lie underground and continue to expand as more vampires join the community. The architecture gives the historical event a permanent physical form: an old house becomes an enclosed society built around the needs of beings who cannot safely live in ordinary sunlight.

More than 300 people live in The Fort, and the community has developed a system of collective work to sustain itself. Residents receive assignments on Sunday evenings and must complete them before the following week. The jobs are distributed randomly and include both important responsibilities and menial tasks. Even Viktor’s children, despite receiving exclusive use of the upper two stories reserved for his family, are otherwise treated like the other residents. The inherited privilege is therefore limited rather than absolute, suggesting that the Great Plague produced a community whose survival depends on shared administration as much as on blood descent.

The Vampire Condition Created by the Plague

The Great Plague’s transformation establishes the biological and social conditions that define the Fort. Vampires require blood to survive and are photosensitive: sunlight dries them, and prolonged exposure turns them to ashes or dust. The community’s underground expansion and regulated labor system follow directly from these limitations. The Fort is not merely a dramatic mansion; it is an adaptive environment built for a population that must secure blood while avoiding the sun.

The vampire society also rejects the idea that its members are wholly separate from humanity. Its self-description emphasizes that vampires are people, even though their dietary requirements and vulnerability to sunlight distinguish them from humans. This contrast gives the Great Plague a double meaning. It is the origin of monstrous transformation in physical terms, but it also begins a long history of social continuity, in which transformed people preserve family ties, work routines, domestic conflicts, and institutional habits.

Family Continuity and Historical Memory

Because Viktor transformed several members of his family at once, the Great Plague remains embedded in the Fort’s internal genealogy. The event preserved not just individual lives but a complicated household: Valnoir is Viktor’s son, Magnus is his brother, Charlotte is his young sister, Victoria is his step-sister, and Lady Harriet is his mother. Lady Mary is identified as his ex-step-mother. Their relationships therefore carry the tensions of an older human family into an immortal or long-lived vampire existence.

The old family conflicts survive the transformation as well. Lady Mary and Lady Harriet used to quarrel repeatedly, with Lady Mary accusing Lady Harriet of being a harlot because of her relationship with Viktor during his marriage. The Great Plague did not erase jealousy, resentment, or marital history; it extended them into the vampire present. In this sense, the event creates continuity rather than a clean new beginning. The supernatural body changes, but the emotional and social residue of the human household remains active.

Narrative Significance

The Great Plague functions as a foundational flashback within the Fort’s history, explaining why a large underground mansion houses hundreds of vampires and why its community is governed through collective work and strict environmental limits. It is also the moment when Viktor’s personal authority becomes the source of an entire social order. His bite creates descendants, dependents, and institutions at once.

Its significance lies in the tension between catastrophe and community. A historical plague becomes the occasion for a new form of survival, but survival carries costs: dependence on blood, exposure to lethal sunlight, confinement beneath the earth, and the preservation of old family antagonisms. The Fort’s later routines, its crowded rooms, its Harem, and its division between inherited family privilege and communal labor all remain consequences of the transformation begun during the Great Plague.
