Diluc X Aether Novels & Stories

The fascination for me lies in the contrast—the raging, brooding winemaster and the gentle, interstellar traveler. It’s a classic elemental clash of fire and wind, earth and sky. Diluc carries so much history, a quiet fury over his father’s death and Mondstadt’s shadows, while Aether is this open book still writing its Teyvat chapters, a patient listener with centuries of unseen life behind him. Fics often play with Diluc’s need to protect clashing with the realization Aether can more than handle himself; that tension between Diluc’s instinctive shielding and Aether’s quiet, proven resilience is where the real emotional friction sparks.

Some stories frame Aether as the one person Diluc can’t intimidate or push away, a calm that disarms his defensive anger without dismissing his pain. I’ve seen beautiful takes where Aether’s ancient, traveler’s perspective offers Diluc a sort of painful solace, a reminder that loss and duty stretch far beyond Mondstadt’s walls, not to minimize his grief but to share its weight. The best explorations don’t soften Diluc’s edges but let Aether find the spaces between them, building trust through shared battles and rare, unguarded moments over a glass of wine at the Dawn Winery, long after the city sleeps.

Razor's answer is basically 'Archive of Our Own' and that's it, but I think the platform question gets more interesting when you factor in curation. AO3's tagging system is unbeatable for finding exactly the kind of dynamic you want—enemies to lovers, established relationship, hurt/comfort, whatever. But the quality there can be wildly inconsistent; you have to wade through a lot of middling stuff to find the real standouts.

I've actually found some surprisingly polished Diluc/Aether fics on smaller, fandom-specific Discord servers. Someone will share a Google Doc link or it'll be posted in a dedicated channel. The vibe is more like a writing workshop, so the prose tends to be tighter, and the character interpretations feel more considered. It's less about quantity and more about a handful of authors really nailing the tension between Diluc's brooding intensity and Aether's weary traveler energy. You just have to know where to get invited.

Honestly, for me, the high-quality content isn't on any single platform. It's scattered. A brilliant one-shot on AO3, a meticulously plotted multi-chapter cross-posted to FanFiction.net, a thread of headcanons on Twitter that's more evocative than most full stories. My reading habits have become entirely aggregator-based because of it.

Crossovers involving Diluc and Aether are a fascinating trend because they often pivot on themes of hidden identities and shared burdens. A really common one I've seen—and frankly overdone but still kinda works—is pulling them into the worlds of 'Final Fantasy', especially VII or XV. The whole 'grumpy guy with a tragic past teams up with the optimistic traveler' dynamic slots right in. Diluc becomes a sort of Avalanche-adjacent figure, maybe even a Turk if you want to flip it, while Aether's journey to find his sister mirrors a lot of FF's lost-sibling quests. They get to clash over methods, with Diluc's vigilante justice versus Aether's more diplomatic approach, before inevitably becoming a powerhouse duo. Another big theme is the 'isekai' or 'transmigration' setup, but reversed: characters from other series get dumped into Teyvat. I've read a few where, say, Cloud Strife or Geralt of Rivia ends up at the Dawn Winery, and the story becomes about Diluc and Aether dealing with this interdimensional refugee. It's less about the crossover characters themselves and more about how their presence forces Diluc and Aether into a protector/mediator role together, which can highlight their latent similarities. Those are the ones that stick with me, the ones that use the crossover to probe their characters rather than just smash action figures together.

A niche but really fun angle is the 'coffee shop AU' or 'modern AU' crossover, but with a supernatural twist. Like, what if the cafe Aether works at in a modern setting is secretly a front for the Men in Black or the Hunter Association from 'Hunter x Hunter'? Diluc, as a wealthy businessman, gets drawn into the weirdness, and suddenly they're investigating paranormal leaks together. It strips away the Genshin power systems but replaces them with another fandom's rules, which forces their relationship to develop purely on personality and wit. I tend to skip the massive battle crossovers—'Avengers assemble in Mondstadt!'—because they often lose the intimate character study that makes the pairing interesting to begin with.
