OSR Dangerous Adventure Location - Port Skagg: The Sunken Docks & Upper Moorings - Warriors of the Red Planet Combined With ACKS II

 Port Skagg: The Sunken Docks & Upper Moorings

Perched on the jagged rim of a dead rift valley, Port Skagg serves as a haven for air-freighters, corsairs, and illicit radium-smugglers. On red-sand worlds like those in Warriors of the Red Planet or low-magic, domain-driven OSR settings like Adventurer Conqueror King System II (ACKS II), this lawless outpost provides a vital hub for grey-market commerce away from imperial tax collectors and city-state blockades.

Key Port Infrastructure

• The Upper Spire (High Moorings): A cluster of iron-girded towers anchored directly into the cliff face. Capable of mooring up to four heavy cloud-galleons or ether-rigs. Steel catwalks sway over a 2,000-foot drop.

• The Sinking Basin (Lower Hangar): A hollowed-out natural cavern system at the cliff base where personal fliers, skiff-copters, and glider-bikes park under camouflage netting.

• The Radium Well (Refueling Bay): A fortified vault housing liquid lift-gas or volatile blue-radium canisters. Run by a secretive guild of renegade engineers who demand sky-high fuel rates.

• The Rust Market: A open-air bazaar built under the shadow of grounded hulls, where black-market cargo, salvaged sky-rigging, and ancient tech change hands.

D10 Encounters at the Docks

d10	Encounter
1	A dozen heavily armed corsairs unloading crates marked with Imperial seal stamps—clearly hijacked freight.
2	A high-altitude scout vessel dock-side with scorched envelope cloth and its crew frantically repairing a damaged keel.
3	Harbor enforcers demanding a 50-gold/crystal "landing tariff" on behalf of a local warlord who doesn't actually own the port.
4	A volatile radium fuel-leak at Bay 3, forcing a frantic evacuation while a fire begins to spread toward nearby powder stores.
5	An escaped thrall hiding in the cargo hold of an anchored trader, begging the party for safe passage out.
6	A sky-sail mechanic offering experimental "lift-pulp" modifications at half price, with a 20% chance of engine explosion.
7	Rival skyship captains involved in a loud, escalating duel with rapiers and ray-pistols over docking rights.
8	Imperial sky-patrol scouts watching the harbor through spyglasses from a distant mesa top, preparing an raid.
9	A shady merchant offering secret altitude maps through the Razor-Wind Gap for a suspicious price.
10	A swarm of predatory sky-ray creatures attracted by the port's generator humming, circling the upper catwalks.

System Mechanics & Adaptation Notes

Warriors of the Red Planet

• Atmosphere: Focus on pulp-planetary romance—bronze hulls, glowing ray-weapons, exotic alien crew members, and dramatic sword duels on high rigging.

• Radium Supplies: Refueling costs 100gp per flier size-class. Low-grade radium fuel carries a cumulative 1-in-6 chance per voyage of engine failure during full-throttle maneuvers.

ACKS II (Adventurer Conqueror King System II)

• Domain & Market Rating: Class V Haven (Lawless). Black-market goods carry a +25% markup when selling stolen goods, but finding specific high-end military equipment requires a successful Market Activity check with a -2 penalty.

• Smuggling Operations: Smuggling cargo through Port Skagg bypasses standard Realm Tariffs (typically 5-10%), but requires a Proficiency check (Larceny, Navigation, or Seamanship) to avoid hazardous wind-shear or cliff collisions on entry.

Baroness Vexia "The Iron Eye"

Port Master of Port Skagg

Formerly a high-ranking officer in an imperial sky-fleet, Vexia abandoned her commission after a court-martial for refusing to fire on a civilian trade barge. She claimed Port Skagg by force five years ago, shooting the previous harbor boss off the catwalks. Cold, calculated, and fiercely protective of her sanctuary, she maintains order through sheer intimidation and an intricate network of paid informants. She wears a brass-and-quartz mechanical eye that detects lie-glows and thermal signatures.

Captain Jax "Ghost-Wind" Vane

Smuggler Captain of the Ether-Clipper 'Night-Stalker'

Jax is a cynical, sharp-witted void-farer who has navigated every dead-rift canyon and storm-belt on the planet. He cares about three things: his vessel, his crew, and getting paid. Known for running low-altitude routes through radar-blind valleys, he carries a heavy bounty in three imperial city-states. Despite his rugged mercenary exterior, Vane abides by a strict personal code—never drop cargo to save your own skin, and never sell out a client who paid in full.

Key Features & Environmental Hazards:

• Low Cover (Cargo Crates @ B): Provides +2 AC against ranged attacks. Pushing a heavy crate requires a DC 12 Strength / Hazard check to crush an opponent (1d6 damage, knocks prone).

• Verticality (Main Mast @ C): A 20-foot climb leads to the crow's nest (+1 to-hit with ranged weapons). Rigging ropes can be cut (Attack AC 10, 5 HP) to swing across the deck or drop a yardarm onto boarders below (2d6 bludgeoning damage).

• The Helm (D): Unattended helm causes the vessel to drift violently into wind-shear (everyone on deck must roll a Saving Throw/Hazard check or fall prone at the end of the round).

• Deck Railing (Outer Edge): Any character moved forcibly against the rail must make a Save vs. Paralyze/Dexterity or be thrown overboard into open air.

Encounters & Event Timeline

The encounter begins mid-air as a rival corsair skiff clamps onto the Night-Stalker's starboard side with magnetic grappling cables.

Round 1: Magnetic Clamps Impact  -->  Round 2: Corsair Vanguard Onslaught
                                              |
Round 5: Engine Baffle Flare     <--  Round 3-4: Grapple Cutting & Sky-Rays

1.Round 1: Magnetic Clamps Impact:Initiative Phase / Boarding Preparation.

Two magnetic grapple lines slam into the starboard hull near (B). Three Corsair Boarders reel across using zip-lines.

• Tactical Objective: Prevent boarders from securing the main hatch.

• Ship Event: High-altitude crosswinds hit the hull. All ranged attacks made this round suffer a -2 penalty due to sudden vessel instability.

2.Round 2: Corsair Vanguard Onslaught:Main Deck Breach.

Four more boarders swarm the port rail, while a Corsair Shock-Captain drops directly onto the Forecastle (A) to disable the forward ray cannon/ballista.

• Tactical Objective: Secure the Helm (D) and prevent the Shock-Captain from spiking the forward gun.

• Action Economy Check: Captain Jax Vane calls out to cut the grapple cables (requires a melee attack dealing 8 damage to a cable or a successful Strength check at B).

3.Round 3: Environmental Complication:Sky-Ray Swarm Attraction.

The commotion and hum of exposed energy systems attract a pair of wild, territorial Sky-Rays (aerial beasts). They swoop in, attacking both crew and boarders indiscriminately at (C) and (D).

• Hazard Event: Every creature in the open main deck must pass a Save vs. Hazard/Reflexes or take 1d6 damage from low-sweeping beast wings.

4.Round 4: Desperate Defense:Rally or Fall.

If at least one grapple line remains intact, reinforcements attempt to breach the aft swivel mount at (E).

• Tactical Choice: A player can attempt to overload the Radium Baffle at (D) (Requires a INT/Larceny check). Success fires a plume of blue superheated gas down the starboard flank.

5.Round 5: Radium Baffle Flare / Resolution:Engine Venting & Escape.

If the Radium Baffle was triggered, all enemies on the starboard rail take 3d6 energy/fire damage and must save or fall from the ship. Remaining boarders attempt a retreat back to their skiff if their leader falls or if they lose half their numbers.
