Dimension 20 is a TTRPG actual-play web series and podcast produced by Dropout. The main show features the Intrepid Heroes with DM Brennan Lee Mulligan, but there have been several "side quests"[1] With other groups of players and DMs. The show is primarily played with Dungeons and Dragons 5th Edition, but other systems have been used in the side quest seasons. While the show is filmed, all the seasons are available in audio format for Dropout subscribers with several campaigns are also available on other podcast platforms.

Because Dimension 20 is an anthology show, nearly every season features new characters and many of them feature new settings as well. This makes the fandom slightly different from other actual-play fandoms such as Critical Role and Friends at the Table, which feature a few campaigns stretched over many years.

Campaigns

As of February 2025, there are 24 seasons of Dimension 20 split into 5 longer campaigns with the Intrepid Heroes (usually about 17 episodes) and 13 shorter side quests featuring other players and DMs (between 4 and 10 episodes). These campaigns range from Escape from the Bloodkeep, a side quest campaign parodying The Lord of the Rings from the villains' perspective, to Misfits and Magic, a Harry Potter parody played with the Kids on Brooms TTRPG system.

Fantasy High

Fantasy High is what can be considered the "main" Dimension 20 world, insofar as an anthology has a main world. It's described as D&D by way of The Breakfast Club, featuring characters in a fantasy high school setting. This was the first campaign featuring the Intrepid Heroes and was quickly followed by two live events, one featuring Brian David Gilbert and another featuring Griffin McElroy. The popularity of Fantasy High resulted in a sequel campaign livestreamed on Twitch following the characters in their sophomore year. A further two "live" events were recorded, "College Visit" for RTX @ Home and "Boys' Night!" for Roll20Con. A third season of Fantasy High covering the characters' junior year was announced in Dropout's 5th Anniversary video.[2]

There are also two spin-off side quests set in the world of Fantasy High: Pirates of Leviathan, an adventure largely unrelated to the main plot of Fantasy High featuring a crew of pirates, and The Seven, a campaign following the titular Seven Maidens who became connected after Prompocalypse.

The Unsleeping City

The other Dimension 20 campaign that's returned for another season is The Unsleeping City. It's billed as "D&D meets NYC" and takes place in an urban fantasy version of New York. The second season was filmed remotely and aired in 2020.

Fandom

As of February 2025, the fandom has over 6,780 works on AO3, most of them rated Teen and Up. Most of the fan works on AO3 currently feature the Fantasy High characters, but most campaigns have at least 5 works. A Crown of Candy has inspired a fan podcast, a regular Big Bang event, and several vids.

Notable Fanfic

The adventuring life has a lot of hazards. Adaine Abernant is less than a month into her freshman year, and she's already picked up her first kill, her first dead party members, and her first life-shattering curse. Now she just needs to hold this mess together for four years, somehow.

Kalina was tired of being a shadow. Operation after operation failed because she couldn't get involved directly. She had eyes and ears, what she needed were hands. And there was a particular pair of hands she had in mind. A child's pair of green hands, already dexterous despite his young age. Those hands were adept at teasing blocks from behind couch cushions and scrawling the correct answers on every assignment, but they grasp at other hands far too often.

When Adaine's parents left her to fend for herself in her last week of middle school, she assumed it was some petty power play and prepared to take care of herself until they came back. She wouldn't realize she'd been abandoned until she'd gotten pretty good at that, and had also gotten a mystery to solve: the disappearance of five girls around town, including one she knew well.

A poly retelling of Misfits and Magic following the four American students at Gowpenny Academy of Arcane Arts learn about magic, mysteries, friendship, and each other.

Riz privately wonders what skill check kissing falls under (Persuasion? Acrobatics? Animal handling?), and how many more times Fabian will pull him onto his lap or back him into a wall before Riz will gain proficiency.
