The Cobalt Caverns

A vast and sprawling cave system lies beneath the city, serving as a hidden stronghold for various criminal organizations, including the infamous Blackwing Assassins, the enigmatic Raven Lords, and numerous other clandestine factions.
Known only to those who operate in the shadows, this subterranean network consists of winding tunnels, hidden chambers, and long-forgotten ruins, offering sanctuary for illicit dealings, covert meetings, and deadly conspiracies.
Some say the deepest reaches hold remnants of ancient civilizations, arcane anomalies, and creatures that have never seen the light of day. To those who call it home, it is more than just a refuge—it is a kingdom of shadows where power is brokered in whispers, blades, and blood.
