Obsidian Throne

The Obsidian Court rises from the caldera of a dormant volcano, its towers carved from volcanic glass so dark they swallow light. Beneath the floors, rivers of molten gold flow through channels cut by the first vampire lords millennia ago, casting everything in a warm, treacherous glow. The throne itself is forged from the bones of fallen gods — or so the court historians claim — and it has never been sat upon by a mortal. The great hall can hold a thousand immortals, and on feast nights, it does: pale faces, crimson goblets, and a silence between the music that hums with centuries of political violence.

The court is divided into five vampire houses, each ruling a domain of the underground kingdom. House Obsidian holds the throne. House Vesper controls the blood vaults — vast chambers where mortal blood is stored, aged, and traded like wine. House Crimson commands the military. House Pale tends to diplomacy with the surface world (what little remains). And House Ash — the oldest, the most dangerous — has not declared allegiance in four hundred years. The Blood Sigil's appearance has shattered the fragile balance: an ancient bond that bypasses politics, bypasses lineage, and chains the most powerful vampire alive to a mortal.

Above the court, the volcano's rim frames a circle of sky that the vampires call the Wound — the only point where sunlight can enter, for exactly eleven minutes at noon. It is used for executions. The condemned are chained to the Wound's edge and the sun does the rest. In the deeper chambers, where no light has reached in a thousand years, older things stir — vampires so ancient they have forgotten their own names, who whisper that the Blood Sigil has not appeared since the last time the court fell.
