Seat of Power: Blackmere House, hidden beneath the Thames embankment near Temple.
Ruler: Duchess Isolde of Blackmere
Nature of Government: Neo-feudal vampire duchy under the ancient Code of the Crimson Seal.

The Duchess
• Absolute monarch by right of bloodline succession, claiming descent from the first English vampire progenitor, Aurelian the Pale.
• Serves as spiritual figurehead and judge of final resort.
• Her decrees are called Nocturnes—laws carved into hematite tablets kept in the Court Hall.
The Court Circle
Consists of the Duchess’s closest servants—her Seneschal, Spymaster, Enforcer, and Priestess. They act as her hand, eye, blade, and heart.
The Council of Five
Advisory body overseeing the duchy’s economic, cultural, and spiritual affairs.
While they cannot overrule the Duchess, the council’s collective refusal to endorse her policies can paralyze the court’s bureaucracy.
