DMs: Don’t Make a Pet NPC, But Sometimes You Can Play a Guide

When I started gaming, people tended to play Dungeons & Dragons with larger parties than now. When game sessions fell short of 8 or more players, dungeon masters often added their own character to fill the group. While common, the practice seemed like a necessary evil at best. The spotlight belongs on the player characters. The players’ choices steer the adventure; their characters’ actions create the story.

Now, DMs never add their player characters to the party, but sometimes they get the same kicks by adding a pet NPC. These game-world avatars let game masters indulge in wish fulfillment. They turn other NPCs into admirers and turn PCs into sidekicks. (Aaron at RPG Musings tells how to spot a pet NPC.)

Over my career as a DM, I’ve read countless how-to-DM guides. They all warn against letting non-player characters overshadow the PCs. I read this advice and probably shared a typical reaction: No duh. I never felt tempted to create a pet NPC, but I never even created an NPC who traveled with the players.

I have run some adventures that added NPCs to the party. To my surprise, the additions worked. They enhanced the game.

Out of the Abyss begins with the new PCs held captive. They meet several other prisoners, and everyone joins in an escape. The PCs and NPCs find themselves deep in the Underdark, traveling together for as long as their paths overlap.

As the adventure progressed, NPCs left the group, leaving a pair traveling companions: Jim Jar, the gambling deep gnome, and Sprout, the young Myconid. I started to see them enrich the game. The ongoing characters became more vivid than the usual walk-on NPCs. The players enjoyed interacting with them. Players never care about the NPCs they meet in passing, but they became emotionally attached to a silent mushroom tot.

Plus, the traveling NPCs served as guides. Most D&D players feel at home in a fantasy setting, but the Underdark should seem alien. The party’s Underdark natives helped me reveal the strange environment. They could give background information and show the way.

Walk-on NPCs could have met the party and dispensed information, but having a guide creates a certain economy. The players don’t need to keep meeting characters they never see again. Instead, the guides save time while they build bonds. (See Use the Small World Principle to Build a Better Game.)

The adventure Cloud Giant’s Bargain also adds an NPC who guides the players. This adventure takes place in a typical (for D&D), flying castle, so its guide doesn’t help introduce the background. But this adventure aims to introduce D&D to new players, so instructor Tulahk guides novices through the adventure. Designer Teos “Alphastream” Abadia writes, “Instructor Tulahk is something I added because it was likely that new DMs would be running the adventure, and it was a higher level adventure with some impressive foes.” Tulahk the NPC gave DMs a voice to remind players to do the sneaking, investigating, and diplomacy that will lead to success. Plus, Tulahk is crabby, talking skull, so when I ran the adventure, I had fun channeling J. Jonah Jameson while calling the PCs empty-headed boneheads and numskulls.

Despite the advantages of giving a party an NPC guide, only add them when they serve a role. And then keep the guide out of the spotlight.

To prevent a NPC from stealing the spotlight, follow two principles:

A guide can’t make decisions for the party. Either create a guide with little interest in the party’s goal, or make the guide too young, too foolish, or too weird to direct the party. Ed Greenwood prevented his NPC wizard Elminster from overshadowing players by making him eccentric. “I never wanted Elminster to be anything more than the ‘old storyteller’ figure,” Greenwood said. “He was the mind-wandering, irritatingly whimsical old man who could OCCASIONALLY be of help to PCs.”

The players must prove more capable than their guide. Tolkien understood the risks of letting a powerful figure upstage his main characters. He kept contriving to have Gandalf leave for important business elsewhere. If a guide brings more power than the PCs, the players will wonder why they showed up. On the other hand, if you mix in NPCs who the players can upstage, and who admire the PC’s exploits, the PCs shine even brighter.

This post lightly updates a version that appeared in January, 2017. In the comments, Alphastream talks more about writing Cloud Giant’s Bargain.

19 Adventures in the Running for 10 Greatest Adventures Since 1985

For my list of the 10 greatest adventures since 1985, nominations, reviews, and reputation led me to consider many more excellent adventures than fit a list of 10. Today’s post reveals the adventures that fell short of my 10 greatest, but merited consideration.


Treasure Hunt (1987) is a first-edition Advanced Dungeons & Dragons adventure by Aaron Allston.

Raw characters with no class levels wash up on the lost island of the pirate Sea King. They advance to first level and beyond.

“As a first adventure for initiates, this can’t be beaten. For old hands who may be tiring of AD&D, it will be a welcome change.” – Carl Sargent in White Dwarf issue 93.


King’s Festival and Queen’s Harvest (1989) are basic Dungeons & Dragons adventures by Carl Sargent.

A pair of adventures that introduces new players to D&D with a variety of linked missions.

“Absolutely the best introductory adventures in print for D&D-game-style fantasy role-playing games (FRPGs). Presented simply and clearly enough for young folks, these adventures are also challenging and entertaining enough for experienced gamers.” – Ken Rolston in Dragon 171.


Ruins of Undermountain (1991) is a second-edition Advanced Dungeons & Dragons adventure by Ed Greenwood.

The first three levels of the mega-dungeon under the city of Waterdeep presents its content with different levels of detail: Some rooms have complete descriptions, while others have terse notes. Most sections remain empty, a canvas for the dungeon master’s creation.

Rated 17th greatest adventure by Dungeon magazine.

Ruins of Undermountain was as much stuff from Ed Greenwood’s original gaming sessions as he could fit into a box. I give Ruins of Undermountain an A+. It will make you a better DM regardless of your skill level. This is a glimpse behind Ed Greenwood’s screen, giving the reader a chance to study his methods, which are very sound.” – Advanced Gaming and Theory


Vecna Lives! (1991) is a second-edition Advanced Dungeons & Dragons adventure by David “Zeb” Cook set in Greyhawk for characters of level 12-15.

After the Circle of Eight, Greyhawk’s legendary adventurers, die trying to stop Vecna’s return, their successors hunt the villain in a chase the across the world of Greyhawk.

Vecna Lives! is one of my favorite adventures from second-edition Advanced Dungeons & Dragons and I’m ecstatic that it’s been made available on dmsguild.com. Even if you never play the adventure, you should go out of your way to read/download/borrow it just to see what an incredible example of storytelling and adventure writing it is.” – Die Hard Game Fan


Night of the Walking Dead (1992) is a second-edition Advanced Dungeons & Dragons Ravenloft adventure by Bill Slavicsek for characters of level 1-3.

Characters investigate a series of murders an disappearances in a village plagued by walking dead.

“The actual adventure is one of the better blends of plotted adventures and old-school adventuring found in the ’90s. Though, there’s a deep, underlying story, it’s not a railroad. Instead, players must investigate and interact with NPCs to figure out what’s happening. Some events act as set encounters, but there’s also a big dungeon (cemetery) to crawl through at adventure’s end. The result maintains player agency while still telling a real story.” – The Fraternity of Shadows


Merchant House of Amketch (1993) is a second-edition Advanced Dungeons & Dragons Dark Sun adventure by Richard Baker for characters level 4-7.

In an event-driven adventure, characters work to end a trade in beetles with a bite that neutralizes psionic power. The quest pits the party against the most powerful merchant house in Tyr.

“This adventure has everything for me: intrigue and adventure coupled with the potential to save the world from a great threat that has just been exposed. So it’s 5 out of 5 stars.” – Warpstone Flux


City of Skulls (1993) is a second-edition Advanced Dungeons & Dragons adventure by Carl Sargent for characters of level 9-12.

Players infiltrate the demi-god Iuz’s nightmare capital to free a military commander needed to defend the Shield Lands.

Rated 26th greatest adventure by Dungeon magazine.

“Periods of stealth and quiet punctuated by short bursts of terrifying combat.” – Retro Gaming Magazine


Night Below: An Underdark Campaign (1995) is a second-edition Advanced Dungeons & Dragons adventure by Carl Sargent that takes characters from 1st level to as high as 14th level.

Billed as the “ultimate dungeon adventure,” this campaign goes from a ruins crawl, to a mine crawl, to a long journey through the Underdark.

“Night Below won’t be to some peoples’ taste, but the vast majority will absolutely adore it. Quite simply, it’s one hell of an adventure.” – Cliff Ramshaw in Arcane magazine.


Return to the Tomb of Horrors (1998)  by Bruce Cordell.

Years after adventurers gutted the original Tomb of Horrors, a dark community has built a city of necromantic evil on the tomb’s site. Even the inhabitants of this fell city have no idea of the true evil that waits beneath them.

Rated 10th greatest adventure by Dungeon magazine.

“The new material is really excellent. Return is a whole mini-campaign, not some rehash of previous work … It offers more by far than the old Tomb of Horrors, and it is more deadly too.” – Gary Gygax


Dawn of the Overmind (1998) is a second-edition Advanced Dungeons & Dragons adventure by Bruce Cordell for characters of level 8-10.

To stop a resurgent mind flayer empire, character visit a world of ancient ruins in search of an artifact of Illithid manufacture. This adventure brings a taste of Spelljammer and sword and planet adventure to conventional D&D.

“This is the third part of the Mind Flayer Trilogy, which was pretty much awesome from start to finish. One of the best D&D adventures of all time.” – Power Score


Die Vecna Die! (2000) is a second edition Advanced Dungeons & Dragons Adventure for characters of level 10-13 by Bruce R. Cordell & Steve Miller.

Die Vecna Die! takes the heroes from the Greyhawk campaign to the demiplane of Ravenloft and then to the Planescape city of Sigil in a quest to claim the Hand and Eye of Vecna—the key to stopping the evil demigod Iuz.

Die Vecna Die! pulls out all the stops, and the result is a massive but tightly constructed adventure with a truly apocalyptic feel. I’m surprised I’m recommending Die Vecna Die! as strongly as I am, but it’s just that good. It’s a great high-level adventure for any campaign.” – Fearful Impressions


Forge of Fury (2000) is a third-edition Dungeons & Dragons adventure for levels 3-5 by Richard Baker.

In a dungeon that captures the flavor of some of D&D’s original, classic adventures, characters battle though five levels of a dwarven stronghold overrun by evil.

Rated 12th greatest adventure by Dungeon magazine.

“I’ve always been impressed with the adventure; for my money it’s one of Wizards of the Coast’s best 3rd Edition era modules. As a basic, flavoursome dungeon crawl I think Forge of Fury is particularly well executed.” – Creighton Broadhurst


Return to the Temple of Elemental Evil (2001) is a third-edition Dungeons & Dragons by Monte Cook designed to take 4th-level characters as high as level 14.

Power rises again in the Temple of Elemental Evil. “Characters battle the power of darkness in Hommlet and beyond, forging their way through hundreds of encounters before reaching the fiery finale.”

Rated 8th greatest adventure by Dungeon magazine.

“Go out and buy the Return to the Temple of Elemental Evil. You will not regret it, and it will become a valuable part of your D&D library. It is one of the best adventure modules ever written.” – Talon on ENWorld


City of the Spider Queen (2002) is a 3.5 edition Dungeons & Dragons adventure by James Wyatt designed to take 10th-level characters up to level 18.

“Daggerdale is reeling from a sudden series of murderous drow raids. As a grave threat to the entire surface world develops in the war-torn dark elf city of Maerimydra, intrepid heroes must discover its source and destroy it, if they can.”

Rated 24th greatest adventure by Dungeon magazine.

City of the Spider Queen is an excellent addition to anyone’s Forgotten Realms campaign or with modifications, any Dungeons and Dragons third-edition game.” – Mania.com


Reavers of the Harkenwold (2010) is a fourth-edition Dungeons & Dragons adventure for characters of level 2-4 by Richard Baker.

In an adventure patterned after Red Hand of Doom, the characters join the resistance and take missions to thwart the army of evil that invaded the Duchy of Harkenwold.

“Definitely one of the best 4E adventures. – Will Doyle.

“I would love to see a 5E update of Reavers of Harkenwold.” – Chris Perkins


The Slaying Stone (2010) is a fourth-edition Dungeons & Dragons adventure for 1st-level characters by Logan Bonner.

Years after goblins overran and occupied a town once settled by humans, the characters enter seeking a lost Slaying Stone, the last of the magic stones created to protect the settlement.

“This is an adventure you won’t want to miss: Not only is it fun and non-linear, but it shows a DM how to better design her own adventures, and that’s something worth reading for any DM, no matter how experienced.” – Kevin Kulp


Dreams of the Red Wizards: Dead in Thay (2014) is a fifth-edition Dungeons & Dragons adventure for characters level 6-8 by Scott Fitzgerald Gray.

Teams of adventurers cooperate to explore a massive dungeon in search of the keys to a phylactery vault held by the evil Red Wizards of Thay.

“A ton of fun. Things get more and more hectic as the alert level of the Doomvault rises. It’s got good pacing, a narrative to it, and some fairly challenging encounters.” – Bell of Lost Souls


Cloud Giant’s Bargain (2016) is a fifth-edition Dungeons & Dragons adventure for level 6 characters by Teos Abadia.

Led by a talking skull, Acquisitions Incorporated interns enter a cloud castle floating over Neverwinter to determine what threats it holds. This superb adventure combines combat, exploration, and interaction with interesting choices into a single session of play. Plus it adds a touch of humor and an unforgettable guide.

How N1 Against the Cult of the Reptile God Changed D&D Adventures For Good

When Dungeon issue 116 ranked the 30 greatest Dungeons & Dragons adventures, N1 Against the Cult of the Reptile God landed at number 19. Ed Greenwood summed the 1982 adventure as, “Detective work, hunting for villains, some monster-bashing, and a settlement detailed enough to use beyond the scripted adventure; a quiet little gem that has it all!”

The adventure’s creation began when Kevin Hendrix wrote an encounter with a reptile cult to serve as an episode in Len Lakofka’s adventure L1 The Secrets of Bone Hill (1981). Lakofka chose not to include the cult, so Hendrix began expanding the idea into a full adventure. In 1981, TSR layoffs claimed Hendrix’s job. The core concept and title reached Douglas Niles for completion. When the module saw print, TSR management felt wary of helping designers gain the clout of name recognition, so Hendrix, now an employee of Metagaming Concepts, received no author byline.

Tracy Hickman and his Dragonlance adventures get credit (and sometimes blame) for moving D&D from aimless dungeon crawls to a story focus. But N1 came first, and it includes a stronger narrative than any of TSRs’ earlier adventures. Niles explained, “I liked settings that allowed the characters to play out a story.” N1 features a story with rising tension and a climactic showdown, but the plot still turns on the players’ choices.

A 1983 review in Imagine issue 3 praised Against the Cult of the Reptile God and touted its “innovative touches.” What made N1 innovative?

Early town adventures tended to stumble

The original Dungeons & Dragons rules say that if a referee makes a map of a town close to the dungeons, “players can have adventures roaming around the bazaars, inns, taverns, shops, temples, and so on.” Because imaginary revelry offers scant fun, roaming town typically focused on shopping and gathering “rumors, information, and legends,” which “lead players into some form of activity or warn them of a coming event.”

Actual town adventures tended to stumble. Typically, the party visits the market and someone tries to haggle: Best case, one player saves a few coppers while everyone gets bored—even the shopper. Later, the players gripe about the tiresome D&D session when the dungeon master stubbornly limited players to shopping.

That’s the best case. Usually, a restless thief picks someone’s pockets, leading to party strife or to a confrontation with the city guard. Such trouble drove D&D designers to rename thieves to rogues. See Why second-edition Dungeons & Dragons dropped thieves and assassins.

In the worst case, the players realize the townsfolk have no chance against a band of experienced killers, leading to murder and looting. See Two weird D&D questions no one asks anymore, answered by the City State of the Invincible Overlord.

The gulf between towns and the sites of adventure

When Gary Gygax wrote T1 Village of Hommlet (1979), he prepared for the worst case. Gygax lists the treasure found in shops and homes, and then discourages looting by inventing a social network able to punish murder hobos.

Gary populated Hommlet with colorful characters who might foster role playing, but I suspect most groups paid them little notice. The real action lay in the Moathouse, because for most players, the heart of D&D lies in crushing evil and winning treasure, not necessarily in that order. In town, evil keeps hidden and gold belongs to a rightful owner.

Unless some goal drives players to talk to villagers, most players have nothing to discuss. In D&D, as in fiction, the really interesting action happens when the characters have both an objective and an obstacle that stands in their way. See A priest, a warlock, and a dwarf walk into a bar and…nothing happens.

After Gygax, other D&D authors tried to connect towns to adventure. L1 The Secrets of Bone Hill provided another home base. U1 Sinister Secret of Saltmarsh suggests that some villagers might be involved with the sinister events at a haunted house, but leaves creating the town as homework for the DM. When I played U1, the DM dropped us at the door to the haunted house and Saltmarsh remained unseen.

N1 entwined a town into the adventure

In Against the Cult of the Reptile God, the characters investigate disappearances in the village of Orlane. Fear and suspicion grips much of the town, while other folk behave oddly. Players need to interact with townsfolk to solve the mystery. A wrong move in town could bring peril.

To modern players, the setup may seem conventional, but N1 became the first D&D scenario to feature an investigation and to bring adventure into town. Before Against the Cult of the Reptile God, a gulf separated towns from the wilderness and dungeons that offered adventure. Until N1 bridged that gap, players found little reason to interact with townsfolk.

Lesson: To capture players interest in role-playing, pair colorful NPCs with a goal that invites interaction.

N1 introduced the event-based adventure

Before N1, every published D&D adventure was site based. The choices that drove these adventures all amounted to a choice of doors or of adjacent hexes. See Why Dungeons & Dragons (and Role Playing) Took Years to Leave the Dungeon.

N1 introduced an event-based scenario where active NPCs affect the course of adventure. The 1983 review spotted the change. “A noteworthy feature is that the unknown adversaries do not tamely wait for the players to come and get them. They are active.” In Orlane, the kidnappings continue as time passes. Party members can even be abducted and compelled to spy for the cult.

This advance marked another milestone. Before Against the Cult of the Reptile God, when players weren’t watching, non-player characters only did one thing: They refilled dungeon rooms emptied by adventurers. In N1, even if the players do nothing, things still happen.

As in one of pulp fantasies that inspired D&D, the sinister events in Orlane lead to a rising sense of peril. Tension increased toward a climax.

Lesson: To make the villains come alive, let them act offstage, and then show their actions in the game world.

Making the most of N1 today

Early D&D adventures like Against the Cult of the Reptile God can still work with today’s rules. Just replace the printed monster stats with numbers from the fifth-edition Monster Manual.

Against the Cult of the Reptile God plays best when the its tension builds over days of game time. To get a sense of passing days, characters need to keep busy. If they focus on rooting out the cult, they tend to solve the mystery before pressure rises. To work best, develop the events of N1 alongside a second adventure that can dominate the characters’ attention. For example, while the PCs make a few forays to the Caves of Chaos, let the disappearances and weirdness in Orlane reach a boiling point. The Encounters-program adventure Against the Cult of Chaos (2013) took exactly this approach by combining elements of N1 with T1 Village of Hommlet and B2 Keep on the Borderlands (1981).

Some critics fault N1 for requiring a 1st-through-3rd-level party to ally with a 7th-level wizard for the final showdown with the cult’s “reptile god.” The wizard overshadows the PCs, but without the ally, the party may die to a single fireball. The adventure itself suggests a solution: Have the wizard give the party a scroll of Globe of Invulnerability for protection during the showdown. Make the elderly wizard too frail to venture into the swamp, but let his familiar guide the party. For more on the risks and benefits of allies, see The Surprising Benefits of Giving and Adventuring Party a Guide.

Among the greatest adventures

Based on quality, N1 merits the standing, but based on achievements, I might rate it higher. N1 set two milestones for published D&D adventures. Thirty-five years later, it still offers lessons to dungeon masters.

The surprising benefits of giving an adventuring party a guide

When I started gaming, people tended to play Dungeons & Dragons with larger parties than now. When game session fell short of 8 or more players, dungeon masters often added their own character to fill the group. To me, the practice seemed dodgy. The spotlight belongs on the player characters.
