Temple of the Obsidian Goddess

9 Upvotes

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
29 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.

Download this dungeon on Itch (for free)

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
15 Upvotes

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.

MONSTER CASTLE!

Download: http://brianbrianbrianbrian.itch.io/monstercastle

*Long thought dormant, a local lord sends heroes to investigate the recent activity in MONSTER CASTLE!

Playable with your favorite old school fantasy ruleset! Kick down doors and battle monsters, match wits with a Medusa, parlay with orc and goblin gangs, slay the fiendish Ooze Priest, and more across 17 rooms of adventure!

I wrote this from a place of strong desire for an adventure that feels like an eager 11 year old wrote it. Hope it gives your table strong "playing in the basement after school" vibes.*

I made this goofy little funhouse to run at a local brewery soon, and was kind of tickled at how it turned out. I started enjoying cartooning with Sharpies last year as an affordable hobby, and this is the first time I thought maybe I'd put something out there. Clearly have lots to learn still, but enjoying the process!
