Portmaster's Vault
Beneath the docks, bribes and blades decide who owns the port.
Beneath the port district lies a fortified customs vault that has become a secret war zone for rival dock factions. Smugglers, mercenaries, and hired toughs now prowl the same corridors, turning old counting rooms and seal vaults into ambush sites and makeshift prisons.
Salt air leaks through cracked stone, mixing with tar, fish rot, and stale lamp oil. Distant shouting echoes off the walls, along with the scrape of boots, the clatter of chains, and the low thrum of hidden waves below the dockside foundations. Torchlight is uneven and smoky, and the deeper chambers feel damp, cold, and charged with the threat of betrayal.
☠ Threat
The vault is being torn apart by a violent power struggle between two dock factions, while their hired enforcer captain uses the chaos to seize the old customs treasury and the blackmail ledgers locked below. If left unchecked, the fighting will spill into the harbor and give the captain control of the port's trade, bribes, and secrets.
History
This complex began as the old Portmaster's Customs Vault, built to store tariffs, ledgers, and contraband seized from smugglers. After the harbor expanded, the vault fell out of public use and became a covert meeting ground for competing dock gangs and private enforcers. Now each faction claims the place as hidden territory, and every corridor bears the scars of a small war fought in silence.
