In her dungeons, a corridor was not just a way to reach the next room. It was a choice. A staircase was not just a connector. It was a clue that the space had depth, age, and secrets below the obvious surface. A sealed door was not filler. It was evidence that someone once had a reason to seal it.

That was the difference.

Plenty of early adventure modules gave players monsters to fight and treasure to find. Jaquays gave them architecture with memory. Her maps looped back on themselves. Her factions shared walls and hated each other. Her ruins had been built, conquered, abandoned, occupied, damaged, and misunderstood before the player characters ever arrived.

The dungeon was not a line.

It was a place.

Older publications may list Jaquays under a prior name. This profile uses Jennell Jaquays throughout, with the spelling she preferred: Jaquays, with the s.

The Fanzine In The Dorm Room

In 1976, tabletop roleplaying was still inventing its public language.

Dungeons & Dragons had appeared only two years earlier. The idea of a published adventure module was still new. There were no settled rules for how a scenario should be structured, how a dungeon should be presented, or how much freedom a published adventure should give the players.

At Spring Arbor College in Michigan, Jaquays co-founded the Fantastic Dungeoning Society and began publishing The Dungeoneer. She edited it, wrote for it, drew for it, and helped shape it into one of the hobby’s important early fanzines.

The first issue included "F’Chelrak’s Tomb," one of the earliest published pre-made RPG scenarios. Jaquays was still a teenager. The medium was barely older than that.

That matters because she did not enter a mature field and refine an accepted form. She arrived before the form had hardened. Within a few years, she would produce two adventures that later designers would still be studying decades after their original publication.

Dark Tower and The Caverns of Thracia did not feel like simple containers for encounters. They felt like discoveries.

Corridors That Loop

By the late 1970s, many published adventures were becoming straighter and cleaner. A room led to a hallway. The hallway led to another room. The adventure moved forward like a queue.

Jaquays pushed the other way.

Dark Tower, published by Judges Guild in 1979, gave players multiple ways in, multiple routes through, secret connections, vertical movement, and rival religious factions sharing the same dangerous territory. The followers of Mitra and Set were not just names on encounter keys. Their conflict gave the place pressure. The players could move through that pressure in different ways.

The Caverns of Thracia, also published in 1979, went deeper.

Its dungeon was built in layers of time. One culture had built. Another had occupied. Another had broken, buried, or repurposed what came before. Lizardfolk, cultists, minotaurs, and other inhabitants were not just stocked into rooms. They were part of an ecology of ruins.

The map told the story.

That phrase is easy to say now because Jaquays helped make it feel obvious. In Thracia, the collapsed passages, hidden levels, old construction, and faction boundaries carried narrative weight. Players could read the place by exploring it. They did not need a narrator to explain that history had happened here. The architecture showed it.

Judges Guild was not known for heavy editorial polish. Jaquays’ work sometimes reached print with rough edges that a stronger production process might have cleaned up. But the underlying design had force. Players remembered the routes. Referees remembered the factions. Later designers remembered the lesson: a dungeon becomes more alive when the players can choose how to understand it.

The Enchanted Wood

Jaquays did not think of her own best work only in terms of the famous D&D titles.

In 1981, she designed The Enchanted Wood for SPI’s DragonQuest. She later described it as possibly her best adventure design. That preference says a lot. She was not chasing only the work that became most famous. She cared about how the design behaved at the table.

The Enchanted Wood used six different openings and twenty-one maps. It took the non-linear instincts from Dark Tower and Thracia and put them into a more deliberate fairy-tale structure. Players could enter the mystery from different angles, then watch those paths cross and deepen.

Jaquays liked strange combinations. She could take pieces that should have clashed and fit them together until they made a new kind of sense. That instinct runs through The Enchanted Wood: familiar mythic ingredients, odd echoes, and encounters that feel surprising without feeling random.

It is one thing to make a dungeon branch.

It is another thing to make the branching feel meaningful.

Jaquays understood that choice has to create knowledge. When players take a different path, they should learn something different about the world. They should meet a different pressure, notice a different history, or discover that the place is larger than their first theory of it.

That was her gift.

Beyond The Dungeon

Jaquays’ design range was wider than dungeon rooms and underground maps.

Griffin Mountain, published by Chaosium in 1981 and co-designed with Rudy Kraft and Greg Stafford, became one of RuneQuest’s memorable wilderness campaign settings. It grew from Jaquays’ earlier Adventures Beyond the Pass material and offered a large region meant for extended campaign play. Instead of a single route through a single adventure, it gave groups a broad place to inhabit.

In 1988, she wrote, designed, and mapped FR5: The Savage Frontier for the Forgotten Realms. That book helped define the North of Faerun for D&D players. Its geography, settlements, figures, and regional identity continued to echo through later Realms products for decades.

The Campaign Sourcebook and Catacomb Guide, co-authored with William W. Connors in 1990, showed another side of her thinking. It was not just an adventure. It was advice about how to build and run campaigns, including material originally developed for the second edition Dungeon Master’s Guide before space limits pushed it elsewhere.

That work matters because it made the implicit explicit. Jaquays had been building complex game spaces for years. Here she helped explain how a Dungeon Master could think about building the larger frame around play.

She was not only drawing maps.

She was teaching people how maps become play.

The Background Generator

Central Casting: Heroes of Legend, published in 1988, took a different design problem and attacked it with the same appetite for structure.

Character creation often begins with numbers. Central Casting began with life.

The book used interconnected random tables to create a fantasy character’s background: family, social position, childhood, disasters, relationships, beliefs, odd turns, and formative events. Traveller had used lifepath character generation earlier, but Jaquays pushed the idea toward biography. The tables did not only produce a playable character. They produced a past.

Heroes for Tomorrow and Heroes Now! extended the approach into science fiction and modern settings. The series became one of those out-of-print tools that people kept chasing because it did a thing no current book quite replaced.

The design was messy in the way living histories are messy. A character could emerge with contradictions, scars, advantages, obligations, and strange connections the player had not planned. That was the point. Jaquays built machines that generated story pressure.

Again, the pattern holds.

A dungeon should have a history before the players enter it. A character should have a history before the first session begins. The present feels richer when it is carrying the weight of what came before.

The Name That Became A Verb

In 2010, Justin Alexander published an essay called "Jaquaying the Dungeon" on The Alexandrian. It took the spatial principles visible in Jaquays’ work and named them for a new generation of designers: multiple entrances, looping paths, secret routes, level connections, meaningful choice, and non-linear exploration.

The phrase spread through the old-school roleplaying community. Designers diagrammed her maps. Bloggers compared path structures. Gabor Lux developed Melan Diagrams as a way to visualize dungeon connectivity, with Jaquays’ work often treated as a benchmark.

Alexander later renamed the technique "Xandering" for his book So You Want to Be a Game Master, after conversations around naming and legal concerns. The lineage remained clear. The design vocabulary had grown out of the way Jaquays built space.

That is a rare kind of influence.

Most designers are copied through rules: a dice mechanic, a character class, a combat procedure. Jaquays was copied through spatial thought. Her work changed how people looked at a map before the first monster appeared.

Goodman Games later treated her early adventures as historical texts worth major restoration. Dark Tower and The Caverns of Thracia received expanded Original Adventures Reincarnated editions, bringing those designs to newer rulesets while preserving the older architecture that made them matter.

The maps had survived the rules around them.

What She Actually Built

Jennell Jaquays did not create a famous dice engine. She did not build a standalone RPG system that became a platform for other publishers. Her name is not attached to a universal resolution mechanic.

What she built was adventure architecture.

That sounds smaller until you sit with what adventure architecture does. It is the structure that decides whether exploration is a hallway or a choice. It decides whether a ruin is a prop or a living place. It decides whether players are being pulled through scenes or discovering a world that can be approached from more than one direction.

Jaquays showed that a published adventure could be dense without being closed. It could be complex without being arbitrary. It could have factions, history, verticality, and loops without collapsing under its own map.

She also built tools for history: the buried history of a dungeon, the regional history of a frontier, and the personal history of a character. Across very different products, she kept returning to the same belief. Play becomes stronger when the present has roots.

Her video game career strengthened that pattern. She worked at Coleco, id Software, Ensemble Studios, and other studios, with credits connected to games such as Quake II, Quake III Arena, and Age of Empires III. She also helped teach game design through The Guildhall at SMU. The medium changed, but the central question remained familiar: how does a player move through a designed space, and how does that space teach them what matters?

That is the throughline.

Where To Find Her Legacy

Jennell Jaquays died on January 10, 2024, in Dallas, Texas, from complications related to Guillain-Barre syndrome. She was sixty-seven.

The loss was felt across tabletop and digital games because her career crossed both worlds. She had been inducted into the Academy of Adventure Gaming Arts & Design Hall of Fame in 2017. In 2024, the Science Fiction and Fantasy Writers Association named her the Kate Wilhelm Solstice Award recipient. Designers, players, and publishers responded with memorials, remembrances, and new work shaped by her influence.

Her legacy is still easy to find.

Read Dark Tower. Read The Caverns of Thracia. Look at the maps before reading the keyed rooms. Notice how often a path bends back toward something you thought you understood. Notice how many ways a group can enter the problem. Notice that the inhabitants seem to be living inside a history rather than waiting in numbered boxes.

Then look at modern dungeon advice and you will see her there too. Every time a designer adds a second entrance, links two levels, lets factions collide, or makes a map reveal its own past, a little of Jaquays’ thinking is still moving through the hobby.

She entered roleplaying before the adventure module knew what it wanted to become.

She drew the corridors that taught it.
