History Fanon / ASongOfIceAndFire

* The notion that there is gunpowder in Yi-Ti. The books mention some pyrotechnical powders used by magicians from the East, Yi-Ti is a FantasyCounterpartCulture of Imperial China, and Imperial China invented gunpowder. So it isn't a big stretch to imagine that the Yi-Tish know gunpowder.

* Related to the one above, many fans take it as a given that the Knight of the Laughing Tree was Lyanna Stark herself. This would also justify how she had Rhaegar got close to each other, since the king sent him to capture the mysterious knight and Rhaegar claimed to have found only "his" shield.

* It's considered practically a given that Young Griff isn't actually [[spoiler:Rhaegar Targaryan and Elia Martell's son Prince Aegon VI]]. Perhaps the most popular alternative theory is that his parents are Illyrio Mopatis and his second wife Serra of Lys. Relatedly: many fans believe that Serra was descended from an exiled member of House Blackfyre, making Griff a scion of the Blackfyres through the female line. This is most frequently held up as a possible explanation for why [[spoiler:the Golden Company]] eventually chooses to support him, despite previously refusing to support Viserys Targaryen (even though both are ostensibly [[spoiler:the heir of the Targaryen bloodline]]); it's well-established that the Golden Company have been staunch Blackfyre loyalists since they were founded by Daemon Blackfyre's half-brother Aegor "Bittersteel" Rivers (they've even been led by at least two Blackfyre pretenders), leading many fans to speculate that [[spoiler:they're knowingly passing a Blackfyre off as a Targaryen to gain legitimacy]].

* Gendry ''Waters''. Like most small folk Gendry doesn't actually have a last name, and would only have taken on Waters if Robert Baratheon knew about his existence and formally recognized him as his bastard. In canon, Robert never did and Gendry doesn't even know he's Robert's son, but most fans refer to him as Gendry Waters anyway, with half the tags on Tumblr and fanfiction putting that as his given name.

* It is also common in fanfics for the eldest sibling to Arthur and Ashara Dayne and parent to Edric Dayne to be a man named Allem.

* It's considered practically a given that Young Griff [[spoiler:isn't actually Aegon VI, son of Rhaegar and Elia. Fans explain this by saying he's the son of Illyrio Mopatis and his second wife Serra of Lys. What's more, Serra is apparently the sister of Varys, both of them being scions of House Blackfyre through the female line. Only a scant few believe he is who he says he is.]]
** Young Griff's [[spoiler:possible true identity as a Blackfyre]] is used by many fans to explain why the Golden Company supports him but shun Viserys despite claiming to be Targaryen loyalists. [[spoiler:They are actually Blackfyre loyalists, as they always have been historically, who are passing off Young Griff as a Targaryen to gain legitimacy.]]

* There are many who believe that Ashara Dayne was actually pregnant with [[spoiler:Brandon Stark's [Ned's brother not his son] child. WordOfGod stated that Brandon may have left "''a little Snow somewhere''" and Barristan Selmy's POV in ''Literature/ADanceWithDragons'' bitterly mentions that Ashara gave birth to a stillborn daughter -- and not to Jon Snow, apparently -- after ''Stark'' dishonored her. Since Barristan has always spoken of Ned with respect and admiration, the only option left is Brandon, who has quite the reputation as TheCasanova.]]

* The Valyrian steel sword "[[RedBaron Red Rain]]" -- which is briefly seen in ''Literature/AFeastForCrows'' in the possession of the Ironborn lord Dunstan Drumm, whose ancestor Hilmar Drumm apparently stole it in a raiding expedition--has perhaps the least description of the six authentic Valyrian steel swords that are shown to exist at the start of the series. Despite this, it's generally accepted by fans that it was originally the ancestral blade of House Reyne, whose emblem is a red lion (hence its name).

* Some fan art has taken to depicting Rhaenys (Rhaegar's daughter) as having her father's purple eyes. This is in spite of the fact that she's been explicitly described as [[StrongFamilyResemblance looking exactly like her mother, Elia Martell.]] As a way of giving nod to canon, the common explanation is that her eyes [[PurpleIsTheNewBlack are a very dark shade of purple, making them look like they're black from a distance or in certain lighting.]]

* Gendry ''Waters''. Like most small folk Gendry doesn't actually have a last name, and would only have taken on Waters if Robert Baratheon knew about his existence and formally recognized him as his bastard. In canon Robert never did and Gendry doesn't even know he's Robert's son but most fans refer to him as Gendry Waters anyway, with half the tags on Tumblr and fanfiction putting that as his given name.

* Again, related to the one above is that some believe that Benjen joined the Night's Watch immediately after Robert's Rebellion [[spoiler: [[TheAtoner out of guilt]] for helping Lyanna run away with Rhaegar, which led to the war.]]
* There are many who believe that Ashara Dayne was actually pregnant with [[spoiler: Brandon Stark's [Ned's brother not his son] child. WordOfGod stated that Brandon may have left "''a little Snow somewhere''" and Barristan Selmy's POV in ''Literature/ADanceWithDragons'' bitterly mentions that Ashara gave birth to a stillborn daughter - and not to Jon Snow, apparently - after ''Stark'' dishonored her.

* Other fan theories taken as true in some circles of the fandom include Jeyne Westerling, or perhaps her mother [[spoiler: bewitched Robb to fall in love with Jeyne]]. Or the Jeyne Westerling seen by Jaime Lannister in ''Literature/AFeastForCrows'' and the one seen by Catelyn in ''Literature/AStormOfSwords'' are two different persons, as their descriptions don't match. This would lead to the speculations that Jeyne is hiding somewhere else and might even be [[SomeoneToRememberHimBy pregnant]]. However, current editions of ''Literature/AFeastForCrows'' remove reference to Jeyne's hips (the source of the theory) entirely, suggesting it was a mistake.

* That [[CleverCrows clever raven]] of Mormont's is commonly assumed by fans to be one of [[spoiler: Bloodraven]]'s many {{familiar}}s, with his unsettling habit of saying the right thing at the right moment especially with Jon Snow around. The fact that [[spoiler: Bloodraven]] himself was also once Lord Commander of the Night's Watch adds to the connection.

** Likewise, there's also fan art depicting her younger brother Aegon VI [[spoiler: (aka Young Griff, if you believe the InUniverse claims about his identity)]] as inheriting their mother's skin tone.

* One of Jon Snow's subordinates is a handsome young man known as Satin, who was previously a prostitute, having been pimped out by his mother as a boy. Fan perception is that Satin is a CampGay PrettyBoy who is always swooning over Jon. However, in-text, there's no indication of Satin's sexual preference (a different issue than the gender(s) he was forced to sleep with), and while Satin certainly likes and respects Jon (as a HeroicBastard, Jon defends fellow "outcasts"), there is not much evidence of this being anything but platonic.

** Likewise, there's also fan art depicting her younger brother Aegon VI [[spoiler: (aka Young Griff, if you believe the InUniverse claims about his identity)]] as inheriting their mother's skin tone, making him a DarkSkinnedBlonde.
