A Song Of Ice And Fire Fanfiction Crossover Novels & Stories

God, trying to mash up the worldbuilding in 'A Song of Ice and Fire' with another series is like trying to mix oil and water, but that’s exactly where the interesting stuff happens. The power structures get completely upended. Picture Jon Snow trying to explain guest right to someone from a modern crime drama, or Daenerys landing her dragons in a world that already has magic systems with different rules. The ‘foreign’ characters often become the ultimate outsiders, which either hardens their canonical traits or forces them to adapt in ways the original text never allowed.

What I find myself looking for is how the crossover recontextualizes the core themes of both worlds. Westerosi politics, all about lineage and feudal power, mean absolutely nothing to, say, the crew of the Enterprise. So the story becomes less about who sits on the Iron Throne and more about a clash of fundamental philosophies. Does might make right, or does diplomacy? It’s a great way to explore characters like Tyrion or Varys, whose power comes from wit, not swords, in a completely new arena.

Honestly, the best crossovers I’ve read ditch the epic scale and just drop one or two key characters into the other setting. Watching Arya Stark navigate the bureaucracy of the Ministry of Magic is infinitely more compelling to me than another massive battle.

Archive of Our Own's got this great little trick for finding the real standout crossovers. If you search the 'A Song of Ice and Fire' tag and filter for crossovers, you can then sort by kudos, but I'd argue that's not enough. What I do is filter for completed works only, then sort by bookmarks instead of kudos. A kudo is a quick click, but a bookmark means someone wanted to find it again, which for these massive, convoluted crossover epics is a much stronger signal of quality.

I found 'The Raven's Plan' that way, where Westeros gets memories from the future, and it's crossed with elements from other medieval fantasy settings. It sounds messy but the execution is shockingly tight. The comment sections on those high-bookmark stories are also goldmines for recommendations, way better than any algorithm.

Reddit's r/TheCitadel has a weekly pinned thread for fic recs. You have to wade through some self-promotion, but people there have encyclopedic knowledge. Someone once linked a 'Game of Thrones' / 'The Witcher' fusion that I never would have found on my own, where Geralt stumbles into the Riverlands. It's those weird, specific niches that the big site searches sometimes miss.

One thing I've seen a lot in crossovers with ASOIAF is characters from other worlds being dropped into Westeros with all their knowledge, and then that knowledge being subverted. The twist isn't that they have the info, but that it's actively wrong or dangerous. A Hermione Granger fic had her using magical forensics to "prove" Tyrion didn't kill Joffrey, only to have Littlefinger frame someone else entirely because he'd already anticipated a truth-seeker. Her meta-knowledge made her a predictable piece, not a game-changer.

Another popular one flips the 'Stark Wank' trope. A crossover brings in a powerful force to back the Starks, making them seem unstoppable. The twist is that this external power fundamentally changes the family, corrupting their honor or making them arrogant, leading to a new, arguably worse, form of tyranny. I read one with the Jedi Order arriving to advise them, and by the end, Robb was basically a Sith Lord justifying conquest with a lightsaber. It's less about good guys winning and more about power distorting even good intentions.

My personal favorite is when the crossover element itself is the twist. The story seems like a standard political drama in King's Landing for 20 chapters, and then a White Walker scout reports seeing a giant robot on the horizon, or a character has a sudden, horrifying realization that the 'red star' in Melisandre's prophecies isn't a comet—it's the Death Star.
