The Adventurer Conqueror King System

In a world of fallen empires, some relics of the past are good only for a beastman’s bludgeon; others make ruin delvers rich. You may start out with no higher ambition than a sack full of ancient coins, but each gold piece you spend ties you into a dynamic realm of commerce and carousing, driven by the hidden engines of court intrigues and distant wars. As you grow in power, will you fight to hold back the darkness looming at the borderlands of an aging civilization, or will you pull down the last decadent barriers to the coming of a new dawn? 

Autarch’s Adventurer Conqueror King SystemTM fulfills the promise of the original fantasy role-playing game by providing comprehensive, integrated support for play across all levels of a campaign. Any referee who has ever checked for random encounters, and every player who has rolled a twenty-sided dice to hit a wandering monster, will find the rules of Adventurer Conqueror King as elegant, familiar, and comfortable to wield as an heirloom sword. The system’s cutting edge is the way every table, chart, and assumption in the game encodes Gygaxian naturalism, Arnesonian barony-building, and the designers’ own experience of hundreds of sessions playing and running old-school games. With Adventurer Conqueror King, you get both the verisimilitude and consistency of thorough world-building with the power of improvisation and discovery through play. We look forward to seeing what you do with these tools! 

Below is the full line of Adventurer Conqueror King products. Our core products give your group everything you need for a comprehensive experience of all tiers of play – dungeoneering; wilderness exploration, warfare, and domain play. Supplemental offerings explore and expand with new (and still compatible!) rules and campaign styles to enhance your games.

ACKS Core Products

Enter a world where empires totter on the brink of war, and terrible monsters tear at the fragile borderlands of men; where decaying cities teem with chaos and corruption, nubile maidens are sacrificed to chthonic cults and nobles live in decadent pleasure on the toil of slaves; where heroes, wizards, and rogues risk everything in pursuit of glory, fortune, and power. This is a world where adventurers can become conquerors – and conquerors can become kings.

Will you survive the perils of war and dark magic to claim a throne? Or will you meet your fate in a forgotten ruin beyond the ken of men?

The Adventurer Conqueror King System™ (ACKS) is a new fantasy role-playing game that provides the framework for epic fantasy campaigns with a sweeping scope.

The Player’s Companion is the first expansion for the Adventurer Conqueror King System™ (ACKS) and an invaluable resource for players and Judges of the original fantasy role-playing game and its retro-clones. Expand your campaign with 19 new class choices. Customize characters with 248 available templates. Make your own character classes using a balanced point-based system 100% compatible with every class in the ACKS core rules and the Player’s Companion. Bring wonder to your game world with a dynamic spell system. Invent your own new spells during play with advanced magic research rules that allow your characters to experiment, make breakthroughs, and suffer side effects. Comprehensive guidelines let Judges determine what level a proposed spell will be and gauge its balance with all existing spells

The Player’s Companion allows you to customize your fantasy game to an unparalleled degree. Open up the hood of the Adventurer Conqueror King System™ and gain new insights into the foundations of the original fantasy RPG.

Tomorrow you will bring the battle to the foe. Tonight you walk among the troops you’ll lead. The mercenaries are veterans and sleep while they can, but the peasants levied from your lands seek courage in tales of your previous victories. In the cover of darkness, you can listen rather than lead. Remember when you were like them? Back when you first entered the dungeon, you wielded a sword to fight for gold, glory, and the favor of the gods. Winning these earned you a throne. Now you wield an army, and fight for the right to rule the domains at war.

Domains at War™ brings the full sweep of fantasy warfare to tabletop gaming and role-playing campaigns with two rulebooks: Battles and Campaigns.

Using Domains at War: Battles™, you can run massive battles between opposing armies using playing pieces on the tabletop. Designed specifically for battles where RPG characters are in command, D@W: Battles makes the deeds and decisions of those characters the focus of its gameplay, and works hard to integrate their actions into the flow of battle. Built from the same mathematics that power ACKS, it generates outcomes like what you’d get if you fought it out on the one-on-one roleplaying scale.

Using Domains at War: Campaigns™, your fantasy RPG characters can raise armies, campaign against enemy forces, and conquer domains. It includes a comprehensive campaign toolkit for use in ongoing games, fully compatible with ACKS’s rules for mercenaries, strongholds, magic, and rulership. D@W: Campaigns also includes a streamlined system for resolving the outcome of pitched battles between army-sized forces, ideal for resolving battles between NPC commanders, where the adventurers are bystanders or front-line participants.

Domains at War is compatible with any fantasy RPG system that uses twenty-sided dice and shares concepts like hit points and armor class. If your players are ready to rule, then your campaign is ready for the Domains at War: Campaigns rules.

Lairs & Encounters™ is the ultimate supplement for fantasy RPG sandbox campaigns. Designed for use with the Adventurer Conqueror King System™ (ACKS™), it is readily compatible with other fantasy role-playing games built on the same core rules.


In Lairs & Encounters you will find:

  • More than 165 ready-to-play monstrous lairs— one for every major monster in the Adventurer Conqueror King System. The lair listings are designed to be used both as dynamic points of interest that can be discovered while wandering through the wilderness and as obstacles to a would-be ruler’s attempt to secure land for a domain.
  • A cartographic compendium of 36 lair maps for the Judge’s use and 6 treasure maps to hand out to your players.
  • A catalog of 30 new monsters, including the chaos hulk, child of Nasga, dire beastman, draugr, desert ghoul, hag, khepri, and mummy lord.
  • New subsystems for sandbox play, including rules for populating 6-mile hexes with lairs based on the terrain and extent of settlements in the region and rules for searching for lairs in the wilderness, factoring in terrain density, aerial reconnaissance, splitting up to cover more ground (never split the party!), and more.
  • Additional mechanics for monsters, including ability scores for monsters, proficiencies for monsters, and young monsters.
  • A complete system for taming and training monsters, with details on the lifespan, roles, tricks, trained and untrained value, supply cost, training period, and trainability modifier of every monster in the game.
  • A complete system for creating your own unique monsters. In the ACKS Player’s Companion we gave you mechanics to create balanced new character classes and new spells; now we bring our same rigorous attention to balance and customization to monsters.

Your players may wander lost in the wilderness of your campaign world, but with Lairs & Encounters you’ll be ready wherever they go!

ACKS Supplemental Products

The Heroic Fantasy Handbook is a rules supplement that brings the flavor of heroic fantasy to your favorite role-playing game. Cleaving away decades worth of assumptions and expectations about how characters heal, fight, and adventure, how magic works, what spells do, and more, the Heroic Fantasy Handbook offers a fresh way to play with familiar D20 fantasy mechanics. In the Heroic Fantasy Handbook you get: 

  • A set of 16 new character classes inspired by the archetypes of heroic fantasy. Defend civilization from the predations of Chaos as a Nobiran champion. Master the power of ancient runes and learn the wisdom of the ages as a runecaster. Unleash your charismatic ferocity as an alluring but deadly warmistress. Plumb magic so dark that no mere human could survive it as a Zaharan sorcerer. Forge your destiny as the Chosen.
  • An entirely new magic system, eldritch magic, designed to capture the flavor of heroic fantasy. Subtle but powerful, eldritch magic brings a new arsenal of effects into your game. Low-level eldritch casters can infuriate their foes, summon minor demons from the Outer Darkness, or call wolves from the forest. High-level eldritch wizards can call giant eagles from distant mountain lairs, lead foes into madness through corrupting dreams, or unleash the hounds of hell to hunt down their enemies. But eldritch magic carries risks, not the least of which is corruption and madness from the black arts.  
  • A new way of creating magical effects, ceremonial magic, for worlds where not every magic-user casts spells in a round. With ceremonial magic, characters can perform lengthy ceremonies from a variety of traditions ranging from the chthonic to the liturgical to the shamanic. Using traditional implements, trinkets, and talismans, the ceremonialist can work miracles – or suffer the terrible consequences of failure  
  • A new way of casting spells, spellsinging, that allows characters to spontaneously weave together new spells on the fly. Use spellsinging to represent the fluid arts of the elves, the psionic powers of a dying race, or the weaving of words of power by island wizards.  
  • Over 155 new spells designed for use by eldritch casters, ceremonialists, and spellsingers. Forget comic-book teleportation and fireballs. If you walk the dark path, be ready to madden your foes with dark whisper, torture them body and soul with iron maiden or even yank out their bones and animate their flensed skeleton as your minions with fillet and serve. If you crave elemental power, get ready to transform rain into acid with rain of vitriol, raze your enemy’s walls with sunder structure, or even call down a starfall from the heavenly firmament.  
  • A set of new rules for heroic adventuring, including fate points, heroic funerals, warrior codes, critical hit tables, new special maneuvers, updates to the mechanics for thief skills…
  • And much, much more!

The Heroic Fantasy Handbook is designed for use with the Adventurer Conqueror King System™ (ACKS™) but is readily compatible with other fantasy role-playing games built on the same core rules. 

Welcome to Kanahu, a dangerous world of pulp fantasy abounding with dinosaurs, Cthulhoid creatures, giant insects, crazed sorcerers, muscled barbarians, and alien invaders. Barbarian Conquerors of Kanahu™ (BCK) presents a host of new monsters, magical items, technology, spells, and variant rules packaged together in this gonzo world. In BCK you get: 

  • A set of 7 new races and 19 new character classes inspired by pulp fantasy. Take flight as an insectoid sorceress as a Bugman Ovate. Serve – or resist – the forces of Chaos as a Deep One Hybrid. Hunt down your prey as a cold-blooded Geckoman Stalker. Master the scientific sorceries of the Outer Darkness as a half-human half-Visitor Nephilim. Wander an alien landscape as a Terran Cosmonaut.
  • Over 60 new monsters. Hunt the fearsome Titanosaur in the jungles of Kanahu. Flee from alien abduction by Visitors in flying saucers. Battle with warbots amidst ruined starships. Confront undead serpentmen in the ruins of lost Sakkara.

  • An entirely new system for alien technology, with dozens of alien artifacts. Learn how to use alien artifacts by conducting research, experimenting in the field, learning from a teacher, or using alien knowledge. If you master scientific sorcery, you can arm yourself with a fusion launcher, laser rapier, and force field belt; pilot flying saucers, hoverbikes, or battle tanks; reprogram robots to serve you; and even learn the secrets of cloning and resurrection.
  • A set of new rules for heroic adventuring, including fate points, heroic funerals, warrior codes, critical hit tables, new special maneuvers, updates to the mechanics for thief skills…
  • And much, much more!

The Barbarian Conquerors of Kanahu setting sourcebook is designed for use with the Adventurer Conqueror King System™ (ACKS™) but is readily compatible with other fantasy role-playing games built on the same core rules. 

Full now—yea, more than full—behold our devastation:

The frantic drum beat, and the brazen horde,

The thundering siege gun, and the blood-slick sword

Devour all diligence, and sweat, and careful preparation.

Down walls and through the town runs always fresh-spilled blood

For eighteen summers now, our river’s yearly flood

Near-choked with corpses, has pushed slowly, slowly on.

     – Andreas Gryphius, Tears of the Fatherland, 1636 A.D.

Guns of War brings you all the rules you need to add the gunpowder, firearms, and artillery of the Age of Pike and Shot into your fantasy role-playing game. This century-and-a-half period was an age of war more terrible than any that had come before, as the technology of battle changed more rapidly than it had in any time in the preceding 3,500 years of human history. It was also an age of apparent anachronism made real, as plate-clad knights battled rifle-armed soldiery, field artillery fired on pikeman, and swords hung alongside pistols on the belts of cavalry.

Guns of War is designed for use with Autarch’s Domains at War (D@W) rules for military campaigns and battles. You will also need a copy of Adventurer Conqueror King System (ACKS), Lamentations of the Flame Princess (LOFTP)or a similar D20-based fantasy role-playing game to use this book.

ACKS Adventures

Over a millennium ago, when the borderlands were in the dark grip of the Zaharan Empire, the empire’s sorcerer-priests erected a profane temple to house the terrible artifact known as the Stone of Sakkara. Using the Stone, the sorcerer-priests could birth monsters and abominations with frightening ease and magically command the loyalty of chaotic creatures. The Stone brought its evil masters great power throughout the fell empire.

In the centuries since the fall of Zahar, the Stone has lain dormant and forgotten. Now it has awakened, and warbands of beastmen have begun to gather sacrifices to power the Stone’s birthing pools again. Local farms and hamlets have been sacked and pillaged, and entire families have gone missing. The local legate has too few men to even patrol the border; he has none at all to hunt down the source of the evil. Adventurers are needed…

AX1: The Sinister Stone of Sakkara is a ready-to-play adventure presented for use with Adventurer Conqueror King System™ and other d20-based fantasy role-playing games. AX1 includes a two-level dungeon filled with chthonic horror along with a friendly stronghold from which your adventurers can explore the region. The Sinister Stone of Sakkara is the perfect introductory adventure for a campaign starting in ACKS’s official setting but easy to adapt to your campaign setting of choice. Begin your rise from adventurer to king today!

Cyfaraun is a city of ancient lineage. The name itself is an Auran corruption of its original elven name, Cyfarawn. Evidence of elven construction is still visible in the city’s oldest district, today called Old Cyfaraun. Many city residents know that Old Cyfaraun was founded atop an earlier settlement – Ancient Cyfaraun, buried by cataclysmic ashes over 500 years ago.

Only the most illustrious sages are aware that the Ancient City was itself built over an even deeper ruin, a Forgotten Cyfaraun, a city brought low by an earthquake almost 2,000 years ago. Forgotten Cyfaraun was reduced to rubble but its lasting legacy is a hidden Nethercity, a treacherous place of twisting tunnels, dusty catacombs, and black, volcanic caves that waits, forgotten and unplumbed – until now…

AX2: Secrets of the Nethercity™ (SOTN) is a ready-to-play adventure scenario presented for use with the Adventurer Conqueror King System™ (ACKS) and other d20-based fantasy role-playing games.

  • Guidelines for adapting the adventure to any campaign setting.
  • Seeds for further adventure in AX3: Capital of the Borderlands and beyond.

The secrets of the Nethercity await!

The Borderlands has been contested throughout recorded history and its landscape is littered with ancient fortresses, blood-soaked battlefields, and dread ruins, all crumbling relics of the empires that once ruled there. Now the dangers facing the Borderlands are greater than ever. Monsters are slipping across the porous border to terrorize and plunder. Travel has grown perilous, and the border forts are becoming increasingly isolated and outmatched. The ambitious, bold, and greedy have begun to gather in Cyfaraun, ancient capital of the borderlands, seeking glory and gold.  There, criminal gangs battle for control of the streets and terrible evils lurk in the twisting tunnels, dusty catacombs, and black, volcanic caves that lie below….

From the imagination of designer and cartographer Simon Forster, creator of the Book of Lairs and the popular OSR blog Sky Full of Dust, comes a new adventure for characters levels 5-7.

Two hundred years ago, the elven capital of Cyfandir fell to the savage assault of the Great Dragon Aisoth, self-proclaimed goddess and sovereign of the lizardmen who followed in her wake. The elves, occupied with the Argollëan War, were unprepared for the attack and the city fell swiftly. The elven residents fled, many dying at the claws and teeth of the lizardmen who waited in ambush in the forest.

Now the city lies in ruins, its walls crumbled and alabaster towers fallen to rubble, and  the forest is crawling across its streets. Ivy and moss cover the walls of once-pristine  buildings, and piles of rubble mark the passage of the dragon. Only the majestic and imposing Great Hall still carries its ancient grandeur. It is there that the Great Dragon makes her lair, sleeping atop the a treasure trove of elven coins, jewels, and artifacts.

Only the bravest adventurers will dare to plunder the ruins of Cyfandir…

AX4: Ruined City of Cyfandir (ROC) is a ready-to-play adventure scenario presented for use with the Adventurer Conqueror King System™ (ACKS) and other d20-based fantasy role-playing games. Explore the vast ruined city of Cyfandir and discover the secrets of the fallen kingdom of the elves.

From the imagination of Courtney Campbell, creater of the popular OSR blog Hack & Slash, comes a terrifying new adventure for characters level 6 to 8.

The Eye Is Opening.

Thousands of years ago, living gods named Khepri wielded powers beyond understanding. Their bizarre magics rived a rent in reality itself. This portal—the Oculus—led to the deepest realms of Chthonic Darkness, but it was not yet fully open. Malign forces, opposed to all life, infested the Oculus, and waited. The Khepri kept vigil over the Oculus till time moved her hand. When the Khepri vanished in the Day Without Night, their Elven epigones took up the watch. In time, the Elves were conquered by the diabolic Thrassian race, and they in turn were subjugated by the Zaharans. Through the millennia, the caretakers of the Oculus studied, waited, and watched.


Now the Awakening is near, the Spheres are coming into alignment, and the Oculus is beginning to open. The dark power is reaching out and for the first time in an age the Eyrie of the Dread Eye is accessible again. As the Eye opens, reality itself comes under further and further  strain. And as rumors of a new valley containing an underground forgotten city filled with untold riches spread out from the Dark Wall, the Oculus continues to open ever wider. 


Eyrie of the Dread Eye is a ready-to-play adventure scenario presented for use with the Adventurer Conqueror King System™ (ACKS) and other d20-based fantasy role-playing games. Discover the vast ruined eyrie of the Oculus and take a stand against the coming Awakening.

High-resolution printable maps are included in a separate .zip file. You can use these maps for Roll20 or similar platforms, or print them out for your table.

Over a thousand years ago, the Zaharan Sorcerer-Queen Semiramis reigned over a court notorious for its decadent arts and lavish opulence. The hidebound nobles of Zahar were troubled by the ascendance of the kingdom’s first female monarch. Semiramis was beset by over one hundred suitors, each one demanding that she marry him so that the kingdom might have a king. Many of these suitors were powerful spellcasters who wove enchantments upon her, but to no avail: The Sorceress-Queen wore the Ring of the Queen’s Heart, a legendary magic item gifted to her by the goddess Nasga that made her immune to her suitor’s charms.

As beautiful and cruel as her goddess, Semiramis instead seduced her perfidious suitors into swearing eternal love to her – then had them slain. The Sorceress-Queen mummified and interred all one hundred suitors in her own majestic sepulcher, where they would serve her as loyally in death as they ought to have in life.

Since then, the sepulcher of the sorceress-queen has lain hidden and undisturbed, its undead inhabitants slumbering in torpor until the prophesied time of the Awakening. But now a reckless warband of lizardmen has broken open the ancient tomb and disturbed evils not seen in centuries…

AX6: Sepulcher of the Sorceress-Queen (SoSQ) is a ready-to-play adventure scenario for characters level 7-9 presented for use with the Adventurer Conqueror King System™ (ACKS) and other d20-based fantasy role-playing games. Dare the dangers of the sorceress-queen’s sepulcher and capture her legendary ring of power.

Each adventure above is based in the campaign world of Cybele – a world of adventure, where a once-majestic empire is slipping into oblivion, and bold and ambitious conquerors are rising to forge new realms from the ashes of the old.  The Auran Empire Primer provides an introduction to:

  • The geography of the world of Cybele and the continent of Aurëpos, with a two-page full color map gridded in 24-mile hexes.
  • The history of the Auran Empire and the surrounding kingdoms, ranging from the sinister Sunset Kingdoms of Kemesh and Somirea, to the barbarian realms of Jutland, to the forgotten empires of Zahar and Thrassia.
  • The customs, fashions, and mythology of the Auran Empire, and the origins, appearance, and naming conventions of its inhabitants and their neighbours.
  • And more!

Designed over 10 years of active play, the Auran Empire setting is inspired by Late Antiquity and intended for use with Adventurer Conqueror King System and similar D20-based fantasy role-playing games.

In the Golden Age of fantasy roleplaying, the dungeon was the linchpin of adventure design and the sandbox was the assumed role of a campaign setting. With Dwimmermount, the Golden Age has returned.
