The Sentry's Forgery: Deadloops in the Mithril Vault
The ancient Mithril Vault, a repository of the lost duergar empire, has reawakened. Its automated defense program, the Sentry Stone Idols, now endlessly cycle through a catastrophic 'Weapon-Slash' protocol, slaughtering anything that moves within its chambers. The cause: a forged signet ring, slipped into the mechanism by a desperate rogue. Now, two duergar factions—the isolationist Vault Keepers seeking to seal the vault forever and the expansionist Forge-Lords who need its mithril to survive a coming war—are locked in a deadly stalemate over how to stop the slaughter. You are caught in the middle, where every choice is a shade of gray and the only clear path is deeper into the madness.
Chronicle Prelude
You stand in the Rust-Choked Anteroom, the crumbling entry hall of the Mithril Vault. The air is thick with metallic dust and the distant, rhythmic *CLANG-HISS* of the Sentry Stone Idols patrolling deeper within. Two groups of duergar, their faces grim beneath their iron helms, argue in hushed, desperate tones near a massive, sealed blast door. One faction wears the pickaxe-and-locket of the Vault Keepers; the other the hammer-and-anvil of the Forge-Lords.
Environmental Traits
The Mithril Vault's Defense Program is trapped in a logic deadloop, endlessly executing a lethal security protocol. The duergar clans are on the brink of civil war over the only two known solutions: one involves a brutal purge and eternal sealing, the other a risky hack requiring resources only the vault itself holds. The Underdark itself is closing in, drawn by the noise of the automated slaughter.
