The Bone Throne Legacy

# Undead# Dungeon# Magitech# Intrigue

You are not the first to seek the lost schematics of the Royal Artificer-King, but you may be the last. The ancient tombs beneath the Sunken Citadel are not merely a resting place for the dead, but a living fortress patrolled by the skeletal honor guard of a dynasty that refuses to die. Their patrols follow complex, trap-laden paths, and within the grave goods of the fallen nobility lie the blueprints for weapons of a forgotten age. Two powerful factions are locked in a desperate race to claim this legacy, and both will demand you choose a side.

Chronicle Prelude

The campaign begins in the crumbling surface outpost of 'Last Vigil', a fortified camp established by the 'Custodians of the Eternal Record'. The air is thick with dust and tension, as scholars and soldiers from two rival factions eye each other warily across the central fire pit. The entrance to the Sunken Citadel, a massive, gaping maw of worked stone choked with rubble and spectral energy, yawns open before you.

Environmental Traits

The Sunken Citadel is a vast, multi-leveled necropolis built by the Artificer-King to house his court in death. The 'trap schematics' are not mere drawings, but arcane blueprints imbued with the king's genius, capable of recreating his legendary, non-magical but incredibly lethal, mechanical and alchemical defenses. Whichever faction controls these schematics will gain an unassailable advantage in the coming regional war, making this a race against time and the undead guardians themselves.

Key Factions & Autonomous Nodes (8)

Captain Valerius Ironheart
A human man in his fifties, his face a roadmap of old scars and new worry. He wears practical, heavy plate armor bearing the Iron Covenant's cog-and-hammers insignia. His movements are brisk, his eyes constantly assessing threats.
High Archivist Theron
A gaunt human scholar in immaculate, dark robes bearing the Custodians' silver scroll insignia. His gaze is intense, his fingers perpetually stained with ink. He carries an aura of intellectual fervor mixed with deep-seated anxiety.
Sergeant Deadstride
The skeletal remains of a knight, its armor fused to its bones by time and dark magic. It moves with a jerky, relentless precision along a fixed corridor, its empty eye sockets glowing with a faint, malevolent light. A corroded key hangs from its belt.
Ghoul Historian Malachi
A hunched, fleshy ghoul with surprisingly intelligent, sorrowful eyes. It wears the tattered remnants of a scholar's robe. It does not attack, instead perching on a sarcophagus and muttering observations to itself in a raspy, conversational tone.
Trapped Scholar Elara
A young human woman in Custodian robes, trapped behind a collapsed display case in the Gallery of Sighs. She is dusty and bruised but unharmed, her eyes wide with a mix of fear and scholarly curiosity.
Covenant Scavenger Jax
A rugged human male in reinforced leather armor bearing the Iron Covenant insignia. He is pinned under a fallen stone statue in the Gallery of Sighs, struggling to keep hold of a schematic fragment.
Skeletal Royal Guard
The animated skeleton of a royal legionary, clad in rusted but ornate plate armor. It patrols in rigid, predictable loops, its halberd at the ready. Its movements are silent save for the clatter of bone on stone.
Spirit of King Ostheon
A shimmering, spectral figure in royal regalia, seated upon the fused bone and metal throne. It does not attack, but its presence commands the chamber. The elite guard animate around it. Its voice echoes not with malice, but with ancient, weary authority.
