• Location: Concealed beneath the ruins of a burned-out Georgian manor, its upper floors accessible through a derelict law office in Temple.

Vampire Significance: The court’s heart — its throne room, catacombs, and treasury.
Mage Significance: Rumored to sit upon a Prime Hallow, corrupted centuries ago. Mages sense an echo of divine law twisted into vampiric dominion.
Conflict Hook: A mage cabal from the Silver Ladder seeks to “purify” the site, claiming it once anchored the Crown of Albion’s Aetheric Leyline. The Duchess forbids intrusion.
