Which Sites Host Original Witcher 3 Fanfiction Crossovers With Other Fantasy Worlds?

Archive of Our Own has become the central hub for the majority of 'Dark Souls' crossover work I've encountered. The tagging system is genuinely a lifesaver for such a specific niche—you can filter for the exact 'Souls' game and the other fandom you want, whether it's 'Elder Scrolls' or 'Berserk'. I've noticed a real concentration of long-form, plot-heavy stories there that treat the bleak worldbuilding with the right kind of grim respect. Some older platforms like FanFiction.net still hold a surprising number of these crossovers, but the search function is a nightmare. You have to wade through a lot of generic 'Chosen Undead gets Isekai'd' premises to find the ones where the author actually understands both source materials. The quality can be wildly inconsistent, but I found a few gems years ago that I still reread, stories where the mechanics of hollowing are explored through another universe's lens. Honestly, the best stuff sometimes feels scattered. I've stumbled upon fantastic 'Dark Souls'/'Bloodborne' fusion pieces tucked away in smaller forums or personal blogs, often linked from subreddits like r/darksouls or specific fanfiction recommendation threads. It feels more like a communal dig than a straightforward browse.

AO3’s filters are built for this exact hunt. Most folks stop at the 'Baldur's Gate 3' fandom tag, but you gotta go deeper. Hit the 'Crossovers' filter first. After that, you can add additional fandom tags—like, say, 'The Witcher' or 'Dragon Age'—to see where someone’s dropped Geralt or a Grey Warden into Faerûn. The real trick is checking the 'Additional Tags' field after sorting by kudos; writers who tag thoroughly often mention 'crossover' or 'fusion' there, even if the main fandom listing is just BG3. I’ve seen some wild ones. There’s a 'BG3/Disco Elysium' mashup floating around where the narrator voice is basically Harry DuBois, and it’s weirdly perfect for Tav’s internal monologue. Tumblr blogs dedicated to specific pairings will sometimes reblog crossover AUs, too, but you have to wade through more moodboards and memes to find the actual stories. Archive of Our Own also has a 'Fandom Fusion' tag, which is less common but usually indicates a really blended world, not just a character drop-in. Those are harder to pull off but can be brilliant when they work.

Finding original Skyrim crossover fics can be a real trip. I mostly rely on Archive of Our Own (AO3) for the real deep cuts – you can filter by the 'Elder Scrolls: Skyrim' fandom and then cross it with literally anything under the 'Crossover' tag. The tagging system is unmatched. Wattpad has a ton too, but the search is messier; you have to wade through a lot of 'Dragonborn reader insert' stuff to find genuine crossovers with other book series or games. I did stumble on a pretty wild 'Skyrim/The Witcher' series on FanFiction.net a while back, but that site feels increasingly dated. For something more obscure, I’ve seen people post original crossover concepts on Tumblr or even Skyrim-specific modding forums, though those are more like snippets and prompts than full stories. It’s a scattered hunt, honestly.

crossovers with straight-up fantasy settings can be a real mixed bag. The best ones don't just smash the universes together; they make the central conflict a cultural and metaphysical clash. I keep coming back to 'The Mage and the Machine-God' over on SpaceBattles. It drops a Grey Seer into the middle of Westeros during Robert's Rebellion. The author nails the sheer, hilarious horror of Skaven logic meeting feudal politics. The Seer isn't some all-powerful wizard; he's a paranoid, backstabbing ratman trying to build a clan from zero, seeing plots everywhere (and often being right). The magic systems grind against each other beautifully—the Winds of Magic aren't just another flavor of sorcery next to Valyrian blood magic, they're an invasive, corrupting force. Another standout is 'Sigmar's Storm in Hyrule', which sounds ridiculous but works on a surprisingly epic scale. It's a 'Total War: Warhammer'/'Legend of Zelda' fusion that treats the Breath of the Wild map as a new, strange continent for a stranded Empire expedition to navigate. The tone shift is masterful—the Empire soldiers see Bokoblins as a new breed of Greenskin, treat the Sheikah tech like ancient Skaven work, and view Hyrule Castle as a fortress to be besieged. It's less about power fantasies and more about the sheer exhaustion of Imperial bureaucracy meeting a world that runs on fairy tales and courage. The writing makes the logistical nightmare of feeding an army in a monster-infested wilderness feel as tense as any battle. Honestly, the worst crossovers are the ones where a Space Marine shows up and just wins everything because bolter. The good ones, like these, force both sides to adapt. The Warhammer side has to confront a world without Chaos as they know it, and the fantasy side gets a brutal, industrial-scale war dropped on its doorstep. That friction is where the real stories are. I'd take a clever, incomplete fic exploring that over a generic power-wank any day.
