Building a Dungeon's Relevant History

It’s Wednesday night. The Aphesus I group is about to sail south toward a cove filled with pearls - and the living dead. At the moment, that’s all they know about it because that’s what their patron, a minotaur captain named Harak, told them. However, as they delve deeper and deeper into the dungeon, they discover more. The undead they’re encountering are huge, 10 feet in size and sport odd, dark blue skin; runes dot the walls, unreadable by anyone in the party; the passages inside are tall and wide; moss-covered, marble statues lay collapsed on the ground, most of a beautiful, lithe woman with a necklace of pearls. As they continue, they find another statue of a huge human holding hands with this same woman; clasped in their molded hands is a giant pearl with a five-pointed star inscribed on it. What could this mean?

That’s a lot, you might be saying. You’re right, but it’s all relevant and adds a ton of depth to the dungeon and its eventual end. Dungeons should be rife with secrets and plenty of clues to those secrets, stuff to give curious players something to look forward and latch on to besides combat. Remember: The three pillars of DUNGEONS & DRAGONS are Combat, Roleplaying, and Exploration, and all good dungeons should contain all three of those elements.

In this installment of Legendary Lessons, we’re learning how to create relevant history for dungeons; this history will not only give your dungeon depth, but tons for your group to discover while they’re within. Let’s roll.

A Pillar of History

Okay - you’re creating a dungeon. Think about something that you think is compelling: Death, devils, love, volcanoes, water, animals, whatever. This is the pillar of your dungeon’s history; everything will be built on it. Take the dungeon in this article’s intro as an example; it’s called Cursed Pearl Cove…

Around 90 years before the party delves into it, a frost giant druid and a female human merchant ran off to the cove. The giant made it a paradise filled with vibrant vegetation, warm springs, lovely animals, and places to store her favorite gems: Pearls. They had many children who learned their father’s ways and lived inside this paradise, thriving. However, the human lady eventually passed as did her half-giant children (who have sped up lives in my setting), leaving the frost giant alone. The cove grew cold and icy, the vegetation rotted, and the giant turned to dark magic. In an attempt to resurrect his love and children, he performed a ritual to raise them that involved necromancy. It failed but he raised them - as mindless undead. Unable to slay his own family, he locked himself away in the depths of the cove. Now, he waits for his family’s undeath to miraculously end, unable to end his life or theirs by his own hand.

The huge undead skeletons and zombies? Half-giants. The runes? Druidic glyphs written in Giant. The large passages? For the giants to move through. The moss and strange, rotting vegetation? Druidic magic gone awry. The pearls? The favorite item of the frost giant druid’s wife. The marble statues? Representations of his wife. Everything in Cursed Pearl Cove stems from the main history I chose for the dungeon: Love. The giant made the cove because of love. He tried to resurrect his family because of love. He locks himself away, unable to kill or flee, because of love.

Decide what your pillar of history is, then write a few sentences about it. Here are a couple example pillars:
  1. Devils: A bone devil has created a shrine to Asmodeus in the ruins of a former temple of Tyr. Lizardfolk tribes nearby have taken interest in the devil’s renovation of the site.
  2. Planar: A grand mountain that shifts between the planes appears near a powerful city. What lurks within comes from all the different planes of the multiverse.
  3. Sand: A hunting group of thri-kreen discovered a collapsed tower beneath the sands of a windy desert. They’re not the only ones using it as a home.
  4. Pain: Lord Aver’s dungeon is infamous for spitting out prisoners who never disobey his orders again. Your friend was wrongfully taken and Lord Aver won’t release him.
Afterward, connect your pillar to some or all of the encounters in your dungeon, from combat to exploration.

For example, the skeletons and zombies in Cursed Pearl Cove are half-giant because of the relationship between the frost giant and human. This gives them additional hit points, stronger attacks, and, because of their druidic heritage, the ability to fling icy balls and walk on water. On top of the half-giant undead, the frost giant had a giant octopus that also passed on and became undead. It haunts the stone landing at the end of the inlet leading to the cavern portion of the cove. There! My dungeon’s combat encounters are more interesting thanks to the relevant history I established using the pillar of “love.” 

Moving to an exploration encounter, the ruined and overgrown statues throughout the cove are fashioned after his wife, himself and her, of their children. They point to their love and her love of pearls - something that comes in during a puzzle deeper in the dungeon. Groups who don’t explore a tad or don’t pay attention to the ambient description of the dungeon will certainly have difficulty later on. As for a roleplaying encounter based on love, the obvious is the ultimate confrontation with the frost giant druid in the depths of Cursed Pearl Cove. How will he react to the news that the party killed his undead family? Will he attack them? Will he muster the courage or power? My party will find out eventually.

Take notice: All of the “history” I created for my dungeon will be relevant to the group when they delve into it. Sure, I might have in my mind how the couple fell in love, the names of their children, and where the wife’s family on the surface is now, but that’s not exactly relevant to the dungeon; perhaps it’ll come into play while portraying the giants, perhaps not. The history you make for your dungeon should be relevant. If it’s a big dungeon, write more! If it’s tiny, write a sentence or two. In both cases, ensure it’s relevant to the moment, to the here and now adventures of the party.

In Summary

Dungeons should have a history, but all of it should be relevant to the moment. To ensure this:
  1. Use a single pillar to build your dungeon’s history (devils, humans, gold, lava, etc).
  2. Connect this pillar of history to a few, some, or all of your dungeon’s encounters.
  3. Trim information that’s not relevant to the group.
I hope you enjoyed this piece! Next week, we’re returning to Musing Over Monsters to dissect an iconic monster both in D&D and the real world: Lizardfolk.

Until then, farewell!

D&D Players and DMs, Be Thankful

It’s Wednesday night. The party are faced with a decision: continue toward the lair of one of their vile foes through cramped kobold tunnels, try to enter through a broken lightning rail, or turn back and face the enemies behind them. If they choose correctly, they’ll reach their destination before the mysterious Vaxilidan can complete the domination of those they hold dear. If they choose incorrectly, their loved ones will become horrific husks twisted by aberrant minds and incurable darkness. Of course, they choose the quickest and safest path: through the kobold tunnels! In single file, they crawl and slip their way down the wet passages until they arrive at a hole that leads into an ancient and flooded crypt. Dragon murals line the walls, kobold packs float in the murky water, and the cracks in the ground remind the party of a defeated foe. Their path forward muddied, they decide to delve into the crypt and a wild night of roleplaying and mad speculation ensues: kobold sarcasm and

How to Begin a D&D Campaign

The world is created, the characters are made, and the starting location is set, but how do you begin a Dungeons & Dragons campaign? There are many lines to check off on your list. Is the starting point created? Are all the session zeros finished? Is the initial plot formulated? Is the opening scene ready to go? As I prepare for the start of my next D&D campaign, Caught in Galen, I’m going to help you or anyone else out there itching to begin a campaign correctly complete their pre-campaign checklist. The D&D Campaign’s Starting Point Where will the campaign begin? This is a key question you should know before your players begin to make their characters that I dedicated an entire article to awhile back. Will the party explore the titanic ruins of a dragon empire on a jungle continent? Will they delve into the depths of the Subterrane in chase of a rogue celestial? Will they begin caught in a giant city of an inherently magical population? Know this before anything e

How to Play an Archfey in D&D

Archfey are part of the god-like trio: archfiends, archfey, and great old ones. Each member of this class is unique, from Mephistopheles the Lord of No Mercy and Orcus the Prince of Undeath, to Hyrsam the Prince of Fools to Dendar the Night Serpent. Distinct from even these unique examples, archfey live on the Plane of Faerie, or the Feywild, where they play court and war amongst each other in a land of impossible flora and fauna. Most of the time, they won’t appear directly in your campaign. They’ll be faraway actors, pulling the strings in the background as your party traverses the world. However, what if you would like an archfey or three to become major players? What if you’d like to use Oberon the Green Lord as a villain? Maybe Titania the Summer Queen as an ally? How about your warlock forms a pact with Hyrsam the Prince of Fools? Well, you’ll need to know how to play one. Outlined below are how I see archfey in my world, Eldar. They might be different in your setting

My Take on Matthew Colville’s 5E Action Oriented Monsters

Soaring into a manifest zone on their airship, the Misty Tide, the party erupts into a pocket of the Elemental Plane of Fire high above a sea of bubbling lava. Surrounding them are hissing fire newts mounted upon burning birds, prepared to hijack the airship and release the fire elementals powering it. The airship’s captain screams, “Hold out! We’ll escape ‘ere in a minute, I’ll get us through!” In response, the fiery raiders attack, lead by a striking fire newt warlock. The combat begins, and she thrusts her molten scimitar into the broiling air. The blade soars between each party member, scorching them with ease before reforming in her hands. Later in the combat, she deftly descends atop her burning bird below the airship, narrowly avoiding a blast of eldritch energy. In the struggle’s final moments, she dismounts from her tiny phoenix in a whirl, leaping thirty feet to gouge one of the party members with her scimitar and deal tremendous damage. Ultimately, she fails; the rest of
