How Can I Write Compelling Dimension 20 Fanfiction Plots?

Dimension 20 stuff is a total playground for digging into character backstories, honestly because the source material practically begs for it. The main casts are so defined by their specific, often messy histories—like Fabian's whole deal with Captain Bill Seacaster, or Riz's missing dad—that the show can't cover every single thread in twenty episodes. So fic writers jump in to fill those gaps. They'll write about what Adaine's life in the Elfage suburbs was really like, the quiet moments of fear before she got out, or the specific incident that made Gorgug so desperate to find his biological parents. It's less about rewriting canon and more about shading in the margins the showrunner had to leave blank for pacing. And the tone varies wildly depending on the Intrepid Heroes season. 'Fantasy High' fics often lean into that mix of teen angst and epic fantasy, exploring how Kristen's crisis of faith might have simmered before we met her. 'The Unsleeping City' stuff gets grittier, looking at Pete's pre-Sophomore year mess or Kingstone's actual backstory as a cop. I've seen some incredible fics that treat the backstory not as a fixed past event but as a living memory that still haunts the character in quiet moments during the main plot, which feels very true to how Brennan layers trauma into his NPCs. My personal favorite thing is when fics cross backstory elements between characters who never got to interact deeply on that level in the show. Like, a fic exploring a younger Gilear being vaguely aware of Fig's infernal heritage through his wife, or how Baron from the Baronies might have crossed paths with a pre-'Crown of Candy' Sir Amethar. It makes the world feel bigger and the characters feel like they existed before the cameras rolled, which is the highest compliment to the original worldbuilding.

I've always been drawn to how fanfiction writers take the foundations laid down by the show and just... build entire new wings onto the house. The nature of 'Dimension 20' as an actual-play series means there's so much fertile ground between what Brennan Lee Mulligan sets up and what the players bring to life in the moment. Fanfiction dives straight into that gap. A lot of the best stuff I've read focuses on the 'what if' of a character's past that was only hinted at. Like, we know Kristen Applebees had a whole repressed evangelical upbringing, right? But the show gives us flashes. Fanfic authors will construct entire childhoods, sketching out relationships with parents and siblings that feel painfully real, adding layers to her rejection of Helio that the original format just doesn't have time for. It’s not just about filling in blanks; it’s about exploring the emotional weight of those blanks. Growth is another huge theme, but it's often handled in a more granular way than the high-stakes level-ups of the show. I read a piece once about Riz Gukgak learning to actually relax, not in a world-saving context, but just on a random Tuesday trying to figure out how to hang out without an agenda. It was slow, awkward, and deeply in character. That kind of story takes a comic relief trait and turns it into a genuine arc about healing from anxiety, which feels very true to the spirit of the source material. Ultimately, I think the fic does what any good companion piece should: it makes you re-watch the original and see more depth in every glance and off-hand remark. The characters feel lived-in, like they have histories that stretch beyond the edges of the screen.

Honestly, throwing someone straight into a niche 'best of' list for Dimension 20 fanfiction feels a bit like handing them the final boss key before they've left the tutorial area. The 'best' stories are often super-deep canon expansions or wildly OOC smut that only hits if you're already marinated in the fandom's private jokes. I'd say skip hunting for a single masterpiece and just wander the tags on AO3. Filter for the 'Dimension 20' fandom tag and then sort by kudos or bookmarks. Anything with a high count and a summary that doesn't spoil a season you haven't watched yet is a solid bet. The 'Adventure Party (Dimension 20)' and 'The Unsleeping City' tags have tons of gen fics that are just the characters hanging out, which is a much softer landing than some epic, 100k-word AU. My real advice? Watch 'Fantasy High' first. Then, when you crave more of Fabian's disastrous bravado or Riz's anxious intensity, you'll have context. The fanfiction that just extends a scene or explores a 'what if' from that first season will feel way more rewarding. There's a one-shot called 'study breaks' about the Bad Kids in the library that's practically canon-adjacent and a perfect little snack.

Oh man, picking 'best' pairings for D20 is so tricky because the chemistry shifts wildly between seasons! The Riz and Fabian dynamic from 'Fantasy High' is a classic for a reason—it starts as this hilarious, reluctant partnership between a tiny, hyper-competent goblin and a himbo with a sword, but the way it evolves into genuine, ride-or-die loyalty is just... chef's kiss. So much fanfic explores that 'what if' space after the end of 'Sophomore Year,' especially with the emotional weight of Riz's dad and Fabian's whole... everything. It’s a great source for both hilarious buddy-cop shenanigans and surprisingly deep hurt/comfort. I also think people sleep on some of the 'A Crown of Candy' pairings because the tone is so intense. Liam and Princess Jet? The tragic, forbidden potential there is a goldmine for angst fics. He's this cinnamon roll of a magic user thrown into a deadly political game, and she's wrestling with duty and rebellion. The fanworks that extrapolate from their few scenes together capture a really specific kind of doomed, bittersweet romance that fits the season's vibe perfectly. For something completely different, the platonic found family stuff in 'The Unsleeping City' is my comfort read. Pete and Kingston’s mentor-mentee thing, or the whole oddball crew at the Dreaming Channel, lends itself to fantastic slice-of-life and urban fantasy AUs that feel grounded and warm. You get less ship-centric content there, but the relationships are just as compelling to explore in writing.

Romance-focused Dimension 20 fanfiction? I’ve been searching for this myself, and honestly, it’s a bit of a scattered hunt. The main hub is definitely Archive of Our Own; there are already some solid collections tagged for specific seasons like 'The Unsleeping City' or 'Fantasy High.' The pairing tags are pretty thorough, so if you’re into, say, Riz and Gorgug or Adaine and Aelwyn, you can filter for that. It’s also the best place to find the longer, slow-burn stuff that really digs into character dynamics. But don’t sleep on Tumblr. A lot of the fanart and headcanons that inspire the written fic live there, and sometimes writers will post drabbles or snippets directly on their blogs before cross-posting to AO3. The tags #dimension20 and #d20fanfiction are good starting points. The community feels a bit more immediate and conversational there, which is great for finding writers who are currently hyperfixated on a specific pairing. I’ve seen a handful on FanFiction.net, but the tagging system is so antiquated it’s almost not worth the effort. You really have to know the character names as they’re spelled in the fandom and dig manually. Wattpad has some, but the quality can be wildly inconsistent. My advice is to set up an AO3 account, subscribe to the tags for your favorite ships, and let the kudos and bookmarks guide you. The fandom is still growing, so new stuff pops up regularly, especially after a new season drops.

So you're asking about 'Dimension 20' crossovers, huh? That's a pretty specific niche. Honestly, I think the appeal comes from the way D20's core premise—the whole 'unsleeping city' or 'fantasy high' settings—acts like a narrative engine. It's a multiverse framework built right into the lore. Fans of 'The Adventure Zone' or 'Critical Role' who are into D20 might love crossovers where characters from those other campaigns get isekai'd into the high-stakes chaos of 'A Crown of Candy' or the urban fantasy of 'The Unsleeping City.' The magic happens in the genre clash. Putting the grimdark characters from 'Coffin Run' into the surreal, neon-drenched world of 'Mice & Murder' creates immediate friction and comedy. Writers get to explore how a character's very specific brand of trauma or power set reacts to a completely different set of rules. It's less about the 'shows' in a TV sense and more about the established tones and genres within the D20 anthology colliding. What really hooks me is seeing how writers handle the distinct DM styles as a kind of cosmic force. A Brennan Lee Mulligan-verse character suddenly having to navigate a world run by the whimsical logic of a different season's ethos is a meta-layer that pure fandom crossovers can't really touch. You end up with stories that are as much about storytelling itself as they are about the characters.

I spent ages trying to find good 'Dimension 20' fics when I first got into the show, and honestly, it’s a bit scattered. Archive of Our Own is the absolute powerhouse for quality and quantity. The tagging system is a lifesaver, and there’s this whole vibrant culture around the Intrepid Heroes campaigns—I’ve seen some incredible AUs for 'A Crown of Candy' that transplant the characters into a cyberpunk setting, which shouldn’t work but totally does. Tumblr is less of a host and more of a signal booster; people will post snippets or moodboards there and link to their full works on AO3. It’s where I first stumbled onto the whole 'Fig and Ayda as awkward college roommates' subgenre. That said, if you’re into the shorter, more chaotic stuff, you can’t ignore Twitter (or X, whatever). The live-tweet reaction fics during new episode drops are a unique beast—they’re like micro-fanfic, all in real-time with the community. Wattpad has some stuff too, mostly for 'Fantasy High,' but it leans younger and the quality is super hit-or-miss. I found one epic slow-burn for Riz and Adaine there that was weirdly profound, buried under a mountain of less polished works. The real trick is to follow the authors you like on AO3; they often cross-post or recommend other platforms where they’ve seen good fics pop up, like specific Discord servers that are basically treasure troves of niche content.
