OSR Adventure Commentary - Adapting C2 The Ghost Tower of Inverness by Allen Hammack to the Hyperborea role-playing game

One of the most remarkable yet frequently overlooked First Edition AD&D modules ideal for OSR-style play is C2: The Ghost Tower of Inverness (by Allen Hammack, 1980). This blog post picks right up from 

OSR Classic Module Commentary - Deeper Integration of B1 In Search of The Unknown By Mike Carr Into the Hyperborea Rpg - Rival Adventuring party & The Pig Faced Orcs Gryth-Kin (Boar-Swine Mutant Thralls)

While overshadowed by famous TSR tournament modules like Tomb of Horrors (S1) or White Plume Mountain (S2), Ghost Tower offers a masterclass in weird, pulp-fantasy dungeon design that fits the modern OSR paradigm far better than many of its contemporaries.

The Setup & Pitch

The characters are convicts offered a pardon by the Duke of Urnst if they retrieve the Soul Gem from the ruins of Inverness—a fortress destroyed long ago by a reality-warping magical cataclysm. The tower itself exists primarily in a displaced, ethereal state, creating a surreal environment where classic dungeon crawling intersects with strange, cosmic physics.

Why It Excels for OSR Play

1. Non-Euclidean, Vertical Layout

Instead of a standard horizontal grid, the core of the module takes place inside the four levels of the ethereal tower, each corresponding to one of the traditional Four Elements (Air, Earth, Fire, Water). The geometry inside the tower is distorted:

• The Air Level: Gravity is localized or non-existent, forcing players to navigate vertical space, floating obstacles, and wind currents using creative problem-solving rather than basic movement speeds.

• The Fire Level: Features a literal giant chessboard environment, but executed with hazard-based logic that rewards player cleverness over arbitrary system checks.

2. Environmental Puzzles & Player-Skill Focus

OSR design prioritizes player skill over character sheet stats, and Ghost Tower is built entirely on this principle:

• Hazards cannot be bypassed with a simple "Disable Device" or perception check.

• Puzzles rely on understanding environmental cues, light manipulation, and the physical properties of the elements inside the displaced plane.

3. The "Time-Loop" & Displaced Reality Mechanics

At the pinnacle of the tower, players encounter the Soul Gem, which bends time and space around it. Interacting with the centerpiece of the dungeon triggers temporal anomalies:

• The dungeon reacts dynamically to the party’s actions rather than remaining a static set of rooms.

• Players can experience strange "echoes" of past adventurers or structural resets if they trigger specific traps, forcing them to map both space and state changes.

4. High Lethality with Organic Faction Opportunities

While designed for 8th–10th level characters, the module translates effortlessly to lower-level OSR retroclones (like OSRIC, Old-School Essentials, or Shadowdark) simply by treating combat as a last resort. The strange inhabitants inside the tower—trapped spirits, displaced monsters, and rival adventuring parties—often have motives beyond "attack on sight," opening up room for negotiation and trickery.

OSR Adaptability Checklist

• System Compatibility: Runs natively in OSRIC, Advanced Labyrinth Lord, or Hyperborea without modification. For Basic/Expert (B/X) or OSE, simply use standard Monster Manual equivalents for any 1e-specific spells or monsters.

• Prep Time: Medium. The module is relatively short (around 20–24 pages), but the Referee should sketch a cross-section diagram of the four elemental levels to easily track vertical movement and gravitational shifts.

• Key Treasure: The Soul Gem serves as a perfect campaign-ending artifact, a high-stakes patron quest-item, or a catalyst for planar travel.

Adapting C2: The Ghost Tower of Inverness into Hyperborea (3rd Edition / AS&SH) fits naturally into the setting’s weird fantasy, sword-and-sorcery, and cosmic horror tone. The core premise—a ancient ruined keep housing a reality-distorted tower and a soul-stealing artifact—aligns seamlessly with the ancient, dying world of Hyperborea.

Setting the Scene & Narrative Hook

In Hyperborea, replace the Duke of Urnst with a tyrant or sorcerer-king from one of the major city-states:

• The Hook: The party consists of prisoners or desperate mercenaries tasked by a High Priest of Thaumaturge in Khromarium or a Patrician of Viridistan to retrieve the Soul Gem (or Jewel of the Nether-Spire).

• The Location: Place the ruined fortress on the bleak, windswept plains of the Barren Wastes, near the Gull-Cliffs, or tucked within the eerie fog of the Spiral Mountain Range. The dungeon is not merely a displaced wizard's tower; it is a remnant of an ancient Hyperborean or Atlantean magico-technological experiment that pierced the fabric of the Black Gulf.

System & Mechanical Conversions

1. Level & Class Equivalents

• C2 was designed for AD&D levels 8–10. In Hyperborea, levels 6–8 offer the ideal balance of high danger, heroic resilience, and reliance on player ingenuity over trivializing spells.

• Class Mapping:

  • Clannish Fighters / Barbarians excel in the physical elemental trials.

  • Magicians and Pyromancers feel right at home with the tower's elemental themes.

  • Warlock, Necromancer, or Witch PCs will find the Soul Gem’s corruptive energy particularly tantalizing.

2. Vril, Sorcery & Horror (Saving Throws)

• Replace standard AD&D saving throws with Hyperborea's 5 core saves: Death, Transformation, Device, Avoidance, and Spell.

• Sorcery & Corruption: The ethereal aura inside the tower requires periodic Transformation or Spell saves against corruption or psychic distress. Unprotected exposure to the Soul Gem should provoke Vril-radiation or sanity-bending hallucinations.

Re-skinning the Elemental Levels

Hyperborea leans heavily into weird science, hyper-geometry, and Lovecraftian dread. Transform the four elemental levels to reflect this:

Level	Original C2 Concept	Hyperborea Adaptation
Level 1	Air Level (Zero Gravity / Wind)	The Void Level: Zero-gravity ambient chamber filled with floating, iridescent spores. Falling upwards into the freezing Black Gulf vacuum is a real risk if magnetic boots or ropes aren't used.
Level 2	Earth Level (Rock & Mud Puzzles)	The Magma & Terran Crucible: Petrified roots of pre-human gargoyles and living crystalline formations that pulse with chthonic energy. Use Gorgon/Cockatrice petrification mechanics.
Level 3	Fire Level (The Chessboard)	The Solar / Plasma Matrix: A deadly grid chamber powered by an trapped, dying star fragment (an ancient Hyperborean power core). Replace chess pieces with automaton guards, Mi-Go constructs, or clockwork brass guardians.
Level 4	Water Level (Drowning / Aquatics)	The Submerged Abyssal Depths: Murky, pitch-black water infused with eldritch slime. Submerged shoggoth-spawn or Deep One hybrid guardians lurk in the dark.

Converting Key Monsters

Most monsters convert directly to Hyperborea baseline stats, but aesthetic tweaks enhance the pulp-horror vibe:

• Shadows / Spectres: Re-skin as Ethereal Phantasms or shadow-creatures spawned from the dream-realms beyond the pole.

• Bugbears / Gnolls (Guardians): Re-skin as Ab-Human Kra'Ki (Pictish tribesmen), Keltish raiders, or mutagenically warped True Human cultists bound to the tower.

• Iron Golem / Automatons: Re-skin as Hyperborean Metal-Constructs or Atlantean Clockwork Horrors powered by crystal batteries.

• The Soul Gem: Treat as a legendary artifact. Anyone attempting to touch it bare-handed must make a Save vs. Death at -2 or have their soul ripped into the gem, turning their body into an empty, violent husk.

Referee Prep Checklist for Hyperborea

1. Cross-Section Map: Draw a simple vertical diagram showing the gravity shifts between the Void, Crucible, Solar, and Abyssal levels.

2. Hazard Tracker: Track light sources strictly—the weird lighting in the tower often distorts non-magical flames, turning torchlight purple or green.

3. Pulp Atmosphere: Emphasize ancient alien metals (electrum, strange alloys), cold stone, and the hum of ancient hyper-technology alongside medieval steel.

Diving Deeper Into Using Neulow Games Supplement Gothic Chillers with The Amazing Adventures role playing game By Jason Vey

 Integrating NUELOW Games' gothic and horror resources—such as their system-agnostic line of classic comic adaptations like Gothic Chillers—into Jason Vey’s Amazing Adventures (Troll Lord Games) creates a natural synergy. This blog post picks right up from 

OSR Commentary Diving Deeper Into Using Neulow Games Supplements with The Amazing Adventures role playing game By Jason Vey

Amazing Adventures uses the SIEGE Engine chassis. While designed to handle standard pulp action, its subsystems for Sanity, Madness, Corruption, and Psychic/Occult powers make it exceptionally capable of pivoting into Penny Dreadful, Victorian Gothic, or 19th-century melodramatic horror.

Here is a blueprint for using NUELOW's Gothic Chillers material directly inside an Amazing Adventures campaign.

1. Architectural Fit: SIEGE Engine & Gothic Tropes

NUELOW’s Gothic Chillers draws heavily on dark romance, Poe-esque psychological collapse, and tragic villainy. To make Amazing Adventures feel less like standard two-fisted heroics and more like atmospheric horror, adjust two core levers:

A. Primes and Attributes

• Wisdom as the Primary Shield: In Gothic horror, physical strength matters less than mental fortitude. Encourage characters to take Wisdom or Charisma as Primes to withstand Sanity checks and horror-induced Madness.

• The "Gothic" Prime Split:

  • Primary (Base 12): Actions guided by deep intuition, resolve, or classic academic lore.

  • Secondary (Base 18): Raw muscle or modern technology, which are often useless against tragic, supernatural forces.

B. Tuning Sanity & Fate Points

• Fate Points as Last Resorts: Limit Fate Point recovery. In pulp, Fate Points pay for narrow escapes; in Gothic horror, let Fate Points be used to resist immediate Madness checks or retain composure when confronted by horrific revelations.

• Sanity Checks via SIEGE Engine:

  • Whenever characters face Poe-esque psychological distress (e.g., live burial, grotesque family secrets, unnatural entities), trigger a Wisdom SIEGE Check.

  • Challenge Level (CL): Scale the CL based on the intensity of the horror (CL +1 for eerie atmospheric events, up to CL +6 for witnessing supernatural atrocities).

2. Adapting Narrative Threads into Adventure Modules

Gothic Chillers comics provide visual layouts, dramatic dialogue, and tragedy-driven plots. You can convert these directly into Amazing Adventures scenarios:

Scenario Framework: The Tragic Antagonist

Gothic villains rarely function as simple monster-manual encounters. They are driven by curse, obsession, grief, or doomed love.

• The Antagonist's Challenge Level: Set their CL not by raw combat power, but by their psychological grip on the location.

• Uncovering the Secret: Require SIEGE checks using Intelligence (Investigation) or Wisdom (Perception/Psychology) to piece together the tragic lore.

• Resolution: Defeating the entity often requires resolving the underlying tragedy (e.g., laying remains to rest, breaking a ancestral family curse) rather than simple physical combat.

3. Class Adaptations for a Gothic Setting

To align the character roster with 19th-century or early 20th-century Gothic horror using Amazing Adventures classes:

AA Class	Gothic Re-Skin / Archetype	Role in a Gothic Chiller
Arcanist / Sorcerer	Occult Scholar / Spiritualist	Investigates cursed relics; performs séances using AA ritual magic.
Gumshoe / Investigator	Alienist / Private Inquirer	Uses deduction to unravel family lineages and dark secrets.
Raider	Grave Robber / Antiquarian	Discovers haunted relics in subterranean vaults and mausoleums.
Brotherhood / Pugilist	Tormented Avenger / Veteran	Fights off physical manifestations of horrors while struggling against personal trauma.
Mentalist	Medium / Mesmerist	Channels spirits, reads lingering psychic impressions in haunted estates.

4. Mechanical Rules Additions for the Chronicle Keeper

If you are running these scenarios using the Chronicle Keepers Guide rulesets, consider these mechanical mechanics:

Atmosphere & Despair Checks

When the party spends prolonged periods in isolated estates, blighted moorlands, or decaying crypts, require a Constitution or Wisdom Check at the end of every rest period. Failure introduces temporary conditions:

• Fraying Nerves: -2 to all Dexterity and Wisdom checks for 24 hours.

• Morbid Fixation: The character becomes obsessed with a specific local mystery, suffering disadvantage/penalties on perception checks unrelated to their obsession.

Monster Design: The "Uncanny" Template

When using monsters from the Amazing Adventures or Castles & Crusades bestiaries:

1. Remove standard physical weaknesses; give the monster immunity to mundane weapons.

2. Assign a Poe-esque Anchor: The creature can only be permanently damaged or banished if the characters exploit its specific narrative flaw (e.g., burning the portrait that holds its soul, speaking its true former name, or destroying the cursed heirloom).

Potential Next Steps

We can take this setup further depending on where you want to focus:

1. Stat Blocks & Encounters: Draft specific Amazing Adventures SIEGE Engine stat blocks for classic Gothic entities (e.g., Spectres of Regret, Cursed Lineage Patriarchs, Animated Portraits).

2. One-Shot Scenario Conversion: Detail a step-by-step conversion of a specific Edgar Allan Poe story into a structured Amazing Adventures investigation module.

3. Custom Sanity/Madness Table: Build a customized SIEGE-compatible Madness table tailored specifically for Victorian or Edwardian Gothic campaigns.

Adventure Commentary on Advanced Dungeons & Dragons - I11: "Needle" By Frank Mentzer For Your Old School Campaigns & Adapted to ACKS II Rpg

 We've covered I11: "Needle" By Frank Mentzer on this blog before back in Feburary 2019.  While high-level classics like Tomb of Horrors (S1) or The Temple of Elemental Evil (T1-4) hog the AD&D 1e spotlight, I11: Needle remains one of the most obscure, under-the-radar official TSR modules produced near the end of First Edition's life cycle.

Originally written as a competitive tournament module for Gen Con XVII (1984) and serialized in Polyhedron magazine before receiving a standalone print release in 1987, Needle is designed for 6 to 8 characters of levels 8–10.

Key Overview & Synopsis

• The Premise: A monarch hires the party for what sounds like a straightforward recon mission: trek deep into an uncharted, hostile jungle to investigate a towering, ancient stone obelisk—known simply as "The Needle"—sitting amid ruined, overgrown ruins.

• The Twist: What begins as a classic hex-crawl through hazardous jungle terrain escalates into sci-fi adjacent cosmic mystery. The obelisk isn't a magical monument—it's a ancient, extraterrestrial landing probe/spacecraft that has lay dormant for ages.

What Makes It Unique (and Infamous)

1. Brutal "Old-School" Attrition: True to its tournament roots, Needle does not pull punches. The jungle trek itself features severe environmental hazards, disease, poisonous fauna, and aggressive megafauna designed to drain resources before players even catch sight of the monolith.

2. Sci-Fi & Fantasy Hybrid: Like Expedition to the Barrier Peaks (S3), Needle blends traditional sword-and-sorcery with weird alien technology. However, unlike S3's gonzo, lighthearted tone, Needle treats the alien element with more subtle, ominous dread.

3. Three-Part Tournament Structure: The module is divided into three distinct phases—the wilderness survival phase, the exploration of the obelisk's exterior/dungeon complex, and the activation/defense phase where players must deal with the obelisk's ancient defense mechanisms and otherworldly occupants.

Why It Was Forgotten

Published in 1987, Needle arrived right during TSR’s late-1e transition period when attention was shifting heavily toward massive settings like Dragonlance and the Forgotten Realms. Because it was published as a generic, standalone "I-series" (Intermediate) module late in the edition's life cycle, it missed out on the classic nostalgia loop that earlier modules enjoyed, making it an obscure hidden gem for DMs looking for a challenging 1e survival-mystery.

Adapting Frank Mentzer’s I11: Needle (1987) to Adventurer Conqueror King System II (ACKS II) translates a tournament module into ACKS II’s sandbox framework, domain management, and campaign procedures.

1. Scale, Scope & Level Calibration

• Original Level Range: AD&D 1e Levels 8–10 (High-Tier)

• ACKS II Target Level: Levels 7–9 (Conqueror Tier / High Veteran)

  • In ACKS II, Level 7–9 adventurers are domain rulers, guildmaster thieves, or arch-mages with access to substantial mercenary units, specialized retainers, and strongholds.

• Campaign Framing: Instead of a generic railroad hire, frame the exploration of the "Great Needle" as a Domain Borderland Expedition. A local Overlord or King grants the PCs a Royal Charter to explore and pacify the Tenebrous Mire—an unclaimed, resource-rich hex-region on the frontier—in exchange for securing a border fortress site and claiming a share of ancient spoils.

2. Converting Core ACKS II Mechanics

ACKS II Universal Target System Integration

• 1d20 Throws: ACKS II standardizes throws against a target value of 20+. Adjust module saving throws and attribute checks to ACKS II Proficiency, Physical Save, Magical Save, or Avoidance Throws accordingly.

• 2d6 Interaction/Morale/Reaction: In ACKS II, 2d6 morale and reaction rolls are replaced with 1d20 throws using modified tables. Apply relevant Monster Reaction Modifiers based on alien or beast classification.

3. Wilderness & Overland Exploration (The Mire Hex-Crawl)

In ACKS II, traversing uncharted wilderness requires rigorous logistics, supply management, and marching order.

Wilderness Mechanics

• Terrain: Dense Tropical Swamp / Jungle (Movement Cost: 3 miles per hex / 4 Movement Points per hex).

• Disease & Environmental Hazards:

  • Mire Fever: Every day spent marching through the inner swamp without a Chirurgeon or Pioneer requires a Physical Save (1d20 vs. 20+). Failure inflicts Sickened (-2 to all throws, -2 AC).

  • Foraging & Supply: Foraging in the inner Mire suffers a -4 penalty due to toxic flora. Mercenary units or retainers without sufficient rations face rapid Morale loss.

Mercenary & Logistic Drag

If characters bring light infantry or supply wagons, the marshy terrain quickly bogs them down:

• Vehicles cannot pass without pioneer units clearing a road (1 mile cleared per day per 50 troops).

• Troop Morale checks are triggered every 3 days spent in the deep swamp unless high-quality rations or divine domain blessings are present.

4. Key Encounters & Faction Conversions

The Jungle Inhabitants

• Swamp Lizardfolk Tribes: Re-stat as ACKS II Lizardfolk Warriors (HD 2+1) and Lizardfolk Shaman (HD 4, Divine Spellcaster).

  • Faction Dynamics: They view the Needle as a sleeping god ("The Sky-Spire"). They can be converted into vassal tributaries or cleared out to lower the domain hazard rating.

• The Mega-Fauna / Jungle Beasts:

  • Giant Constrictor Snakes & Hydra Variants: Use standard ACKS II Monster Stats; apply Armor Penetration rules to large beasts.

The Needle (Extraterrestrial Probe)

Inside the obelisk, standard sword-and-sorcery assumptions shift to ancient technology.

• Alien Defense Automatons (Constructs):

  • Stats: HD 6 to 8, AC 6 (ACKS II scale), Cleave 2.

  • Special Trait — Kinetic Buffering: Metallic construct hulls gain +2 AC against non-magical slashing and piercing weapons.

• Energy Traps & Ray Emitters:

  • Resolve laser/plasma traps as Avoidance Throws (1d20 vs. 20+). Damage follows ACKS II Heroic damage scaling (e.g., 6d6 Force damage, save for half).

5. Domain, Treasure & Economy Integration

In ACKS II, XP is earned primarily through gaining wealth and bringing treasure back to civilization.

Treasure & Strange Relics

Convert Mentzer's original sci-fi loot into valuable ACKS II commodities, trade goods, and arcane components:

Original Item / Relic	ACKS II Equivalent & Value	Domain & Campaign Utility
Alien Power Cells / Crystals	Rare Mineral Trade Good (5,000 gp each) or Arcane Repertoire Catalyst	Can be sold to Mage Guilds for XP or used as power sources for magical research/construct crafting.
Metal Alloy Plating	Exotic Metal Trade Goods (10,000 gp total haul)	Reduces stronghold construction costs by 20% if reclaimed by dwarven or master engineers.
Alien Defense Matrix	Wonder / Domain Artifact	Once repaired via Engineering proficiency checks, acts as an automated ballista/defense tower (+2 Security to the hex domain).

Hex Clearing & Domain Founding

• Clearing the Hex: Eliminating the wandering threats and the alien defense system successfully clears the 6-mile hex.

• Land Value & Domain Investment:

  • The hex yields high-value timber, exotic dyes, and rare herbs, establishing a Base Land Revenue of 4 gp per 9 gp (higher than average due to rare jungle exports).

  • Domain Morale Impact: Unearthing alien horrors without properly consecrating or securing the site causes a -2 Domain Morale penalty among peasant settlers due to superstitious fear. A Divine caster must perform a formal Consecration ritual to normalize peasant morale.

6. Judge’s Master Checklist

1. Prep the Hex-Crawl: Map a 3-hex radius around the Needle using ACKS II wilderness rules. Assign encounter frequencies (1 in 6 per watch).

2. Track Encumbrance & Rations: Enforce strict ACKS II slot/weight encumbrance for tech salvage—alien gear is heavy and awkward to haul through swamps.

3. Mortal Wounds: Remind players that alien plasma weaponry inflicts severe negative HP penalties, altering survival rolls on the ACKS II Mortal Wounds Table.

Here are the full ACKS II stat blocks for the alien constructs and a hex-by-hex wilderness key for the surrounding jungle, structured specifically for your campaign.

• Faction Dynamic:

  • The tribe worships the Needle in Hex 0404 as "The Sky-Spire of the Iron God."

  • Reaction: Neutral. If treated with respect (or bribed with 500+ gp of steel weapons), Shaman Vraask reveals that "iron spirits with glowing eyes" kill anyone who touches the spire's base.

  • Domain Prospect: Can be subdued into a Tributary Vassal Tribe (yielding 100 gp/month in exotic pelts/spices) or cleared out to lower hex danger.

Hex 0404: The Needle (Central Objective)

• Terrain: Cleared Crater / Overgrown Alien Plinth

• Description: A 300-foot-tall, smooth, jet-black stone obelisk sticking out of a glassified impact crater at an odd 70-degree angle. Vegetation refuses to grow within 100 yards of its base.

• Key Features:

  • The Entrance: A hair-line seam on the southern side opens when an organic body approaches within 10 feet, revealing a metallic airlock chamber.

  • Perimeter Defense: 2 Sentinel Drones hover around the upper crown of the needle.

  • Domain Clearing Condition: To clear this hex for domain settlement, characters must breach the inner core, destroy or reprogram The Core Apex, and neutralize the security grid.

Hex 0504: The Sinking Ridge

• Terrain: High Jungle Ridge / Ironwood Forest

• Description: Elevates above the swamp waters, providing a clear view of the surrounding Mire.

• Details:

  • Contains a rare stand of Ironwood Trees (Valuable Domain Lumber Source: +1,000 gp per month to domain revenue once cleared and settled).

  • Inhabited by a territorial Wyvern (HD 7) nesting at the highest point.

Domain Revenue Summary for Clearing the Region

If the party clears Hexes 0101 through 0504 and establishes a domain:

• Base Land Revenue: 4 gp per family (Rich frontier exports: Ironwood, pitch, exotic dyes).

• Special Hex Revenue: Up to +1,800 gp/month in trade commodities once infrastructure (logging/pitch harvesting) is funded.

• Domain Security: Base 0 (+2 once Needle Defense Matrix is reclaimed and repaired by an Arcane/Engineering Specialist).
