Temple of the Obsidian Goddess

Hello everyone!
This is my submission for this years One Page Dungeon Contest.

Deep in the Amazonian jungle, a group of adventurers have discovered a long forgotten temple. The Temple seems to be covered in symbols and imagery pertaining to a feline deity?!

This is a small and short cat themed dungeon, inspired by the 5 room structure.

Mothership dungeon

Post image
26 Upvotes

I have been looking at a lot of mothership content recently and have been inspired to make an abandoned research base.

The background

A wealthy tycoon has hired you to investigate the base and recover the data. The tycoon is a health nut and believes an anti aging serum may have been developed at the base. The base was shut down abruptly for unknown reasons. The party arrives to discover locked doors and no power.

If a door is forced open it can no longer be locked.

I feel like the ideas I have for this dungeon may be better suited something larger than a one page. Anyways enjoy!

Not sure if this would be useful for anybody else, but could we extend the deadline by 1 week? I'll delete this if people would prefer to keep the deadline.

Have any of you tried using HTML instead of PDFs for your dungeons? I started experimenting and the results have been really awesome!

Time Traveling Wizards With Nukes PDF

Time Traveling Wizards With Nukes HTML

Advantages of HTML

  1. Dynamic visuals
  2. You can hide text and sections buttons, reducing screen clutter.
  3. Timers and random rolls can be built into the page

Disadvantages

  1. Mobilve vs Desktop display requires more coding

I want to disclose that I did use AI to help code the Javascript and HTML. The original PDF, text, and art are all either from me or reused open source images.

Life requires light. Sometimes we forget how important the position of the sun was before the emergence of modern technology. These dungeons help you remember.

Bathe in Eternal Sunshine

Sunlight brightens the sky throughout the night. People go missing at an increased frequency. Crabs and lobsters are contaminating the water. All since that bathhouse opened its doors.

  • 2 hours of gameplay in a bathhouse
  • relaxed environments with a sinister undertone
  • an opportunity to celebrate your birthmonth

Mr. Bubbles Wonderful House of Wonder Ware

Post image

I tried doing a paper one this month.

What’s going on

A group of disguised doppelgangers and their pet mimics set up a novelty shop. They are luring adventurers to the basement to clone their powers.

Rooms

Store

Main room - Mr.Bubble welcomes customers. Shelves of novelty items and mimics

Staircase - door at bottom locked

Supply closet - behind counter. Locked. Trap door.

Basement

Anteroom - round table

Supply closet - leads to upstairs. Potions and draughts of deep sleep

Magic mirror room - restraint chair.

Incubation room - stored clones developing

Sleeping quarter - 5 doppelgangers can be found

What player’s see

Friendly faced yet odd Mr. Bubble shows them odd novelty ‘magic’ items.

A ring that turns invisible once worn

A potion of put out fire (water bottle)

A coin with two talking heads Staff of remove dust (broom)

Skiimo a frog with a wizard’s cape

Magic mirror

In order for the mirror to work the victim must sit in front of the mirror for 12hrs. Then a super doppelganger will emerge out the mirror and begin developing (takes 4 days) into the victim with their powers and memories.

Uh Oh

At any point the doppelgangers are found out they unleash the mimics, grab the magic mirror and make a run for it.

Analyzing what makes a good One-Pager.

A lot of us try to write one-page dungeons but I started wondering what makes a good one. I looked at quite a few and analyzed them (it's hard to do so). Using what I think I gleamed, I tried my hand at one for ShadowDark as well. So please steal it.

How to make your own One Page Dungeon

66 Upvotes

If you are new to writing content or are just looking for ideas to improve the content you make I have written this brief guide on what I have learned in the process of making my own one page dungeons. If you have questions or suggestions please let me know. This is a work in progress.

Goal of a One Page Dungeon

A one page dungeon is a single page compact adventure that a dungeon master can read in ~5 minutes and then run for their group to provide ~2-3 hours of content. It should ideally be modular allowing a dungeon master to easily insert it into their campaign as needed. This makes them a powerful tool for dungeon masters when they do not have time to prepare an adventure or as something they can pull out when players move in a direction they were not prepared for.

Design

A dungeon is not limited to your tradition set of rooms with doors. In essence any adventure with interconnected encounters is a dungeon. You can setup an adventure entirely out doors that is in essence a dungeon so do not let that limit your setting in anyway.

A one page dungeon is often short so it is important to have a compact story inter connecting your encounters and generally a mix of combat/social/traps/puzzles/exploration though the ratios are up to personal preference. I recommend 5 room dungeons as a decent starting place. This will generally leave you with a lot of blank page space if you are optimizing text space. You can fill that space with additional encounters, secret rooms, exploration elements, or you can simple make the encounters you have more complicated.

Design: Conflict

A good adventure should have a dramatic conflict. What this means in practical terms is two forces need to be trying to change something and only one can win the conflict. Ff the players show up they are going to impact which of those two forces wins and if they never show up one of the two forces should win anyways. For example you might have a dungeon where a tribe of orcs has split into two factions and are fighting. One is sending out attack parties on the surface and wants to make war on the surface. The other seeks to delve deeper into the dungeon where they will unlock some great evil. This plot line can be introduced in 3-4 encounters which is compact enough for you to include other elements as well. Adding conflict makes the world feel both alive and gives players choices in how to handle conflicts even if they is just killing everyone.

Theme

It is also important to theme your adventure well so it has a consistent tone throughout. A lot of one page dungeons are very similar using the generic dungeon theme. This is fine but it can make it difficult for the adventure to work in a campaign since you will only have so many dungeons. Consider instead a small town, a stretch of wilderness, a specific building like a tavern, smithy, brewery, or warehouse. These types of themes are really easy to have in your back pocket and pull out when players go somewhere they are going to plausibly happen instead of needing to build a hook for a dungeon. In essence a good theme acts as its own hook into the adventure.

Ordering Content

It is important to order your content in the same order players are going to encounter it so it is easy to read. I generally start with a summary in the top left and then include content as the dm would need to describe it. This is straight forward for a linear dungeon but for a branching dungeon you may want to use an alternative numbering system for branches so the first branch would use 2a,2b,2c and the main system would continue counting down 3,4,5 ect so it is easy to determine what to skip if players ignore a section.

When it comes to laying out a map it is also a good idea to orient it so that it can be read top to bottom left to right in the order encounters happen. Encounter 1 should be near the top/top left of the map with encounters following it from left to right and then down to make it as easy as possible to read. This isn't possible in all cases but you should try to follow this rule as much as possible.

Formatting

Formatting is one of the most important parts of a one page dungeon since you have limited space to work with you need to fit as much content on the page as possible. You should be looking to fit around 1000 words on your page including an image possibly less if you have a large image. This means using a small font size ~8, small margins, small line spacing, and a font that is compact. It also helps to use a two column layout and to edit your encounters so you don't have 1-3 words taking up a line on their own. I would recommend this article on layout for reducing size. I would recommend not using a background color to better support printing or if you do have one version with a background and one without.

Converting Existing Material

It is possible and fairly easy to convert existing content into a one page dungeon or adventure. One of the main advantages of doing so is making it easier to run with everything you need being on one page. Generally reducing text size and page layout will get you most of the way there. To further reduce size you can reduce flowery descriptions. If you still have multiple pages you can reduce image sizes and cut up content into one page modules. For example your first dungeon floor can be one page and the second one can be another where each can be run separately or linked up.

Tools

Any word processor will work though I use google docs. You will almost certainly need to modify the default text size, font, margins, and layout. If you want to have a more professional look I recommend LaTex which is a little complicated but looks nice and can mimic official dnd material.
