"#...enter jaina monsterfucker extraordinaire--" Ok, based on this tag, do you have any headcannons about how cross-racial relationships are viewed in Azeroth? I also don't play the game and only read fanfic, so I'm curious if you have particular headcanons that are/n't what might actually be in the source material. Though Sylvanas might be considered actually "monstrous" by some in a way other races aren't to each other, the question still stands. Jaina/Thrall is also a popular headcanon aswell
(from a comment on @mylordshesacactus's Reunification)
The fundamental problem here is that Azeroth is phenomenally racist, and Warcraft itself is also phenomenally racist. The racism is coming from inside the house. It's baked in. The underlying idea is that race war is a real and inevitable thing and of course these groups will hate each other because they look different, and also the Evil and Uncivilized groups are expressly based on non-European real world people.
Like, in the lore, there's a handful, maybe a dozen, of known mixed-race characters. There's scads and scads of roleplayers who have PCs of every mixing imaginable, but in canon? Like, the ones off the top of my head are (a) Vereesa's children and (b) the result of rape. That's it.
So, Watsonian, we have peoples who are so rabidly hateful that there are extraordinarily few cross-racial relationships, even fewer that are consensual, even though all evidence is that everyone could interbreed (...even if they are, in fact, from space). And the Doylist explanation is that character morphs are hard and the devs are lazy and they would rather write a worldstate where no human has ever fucked a troll than put some effort into it.
The upshot of all of this is that, despite living in a world where there are, commonplace, a dozen humanoid races of varying levels of 'monstrosity', all available evidence is that Azeroth standards of 'monsterfucker" exactly map to American standards, aka, Jaina is a monsterfucker by [checks notes] having sex with Kalec in human form.
Humans don’t have relationships with quel’dorei. They don’t have relationships with dwarves, or with gnomes, or any non-human race. It’s not just human exceptionalism, for once, because there’s also no evidence of any relationships between, say, Darkspear trolls and orcs either.
Meanwhile, Jaina’s canonical relationships are with Mr Compulsory Heterosexuality, and also a dragon. Her primary fanon ships are with an orc (as you mention), a kaldorei, and…Sylvanas. Arthas aside, Jaina…doesn’t express interest in any humans. Simple explanation is that Jaina isn’t really into humans. Humans are boring, humans are easily spooked.
As I write her, Jaina’s got a million kinks, and one of them is she wants a little danger. A little spice. Something more than vanilla in missionary, something with an edge. Something interesting, something novel, Thrall has this in spades—this isn’t necessarily about playing into the violent savage thing but y’all, that size. Holy shit. Pained? Nothing but edges.
So Jaina’s not necessarily, say, into something that’s properly an eldritch abomination or completely non-humanoid—although I’m open to arguments on that front—but I’m very confident she’s after something non-human that would absolutely be called ‘monsterfucking’ by your average human on Azeroth.
(Related: It’s soooooo fucking obvious that not only do the Windrunner sisters have a human fetish, but that it’s not at all common or acceptable in Quel’thalas—even aside from the ‘walked through a portal’ bit, Alleria’s hardly in Quel'thalas after marrying Turalyon, Vereesa lives in Dalaran. There’s extenuating circumstances in both cases—Turaylon’s a dick, Rhonin has tenure in Dalaran—but it sure is interesting that our two human-elf relationships both live(d) with humans and Vereesa doesn’t return to primarily socializing with other quel’dorei until after Rhonin’s death. Then there’s Sylvanas and Nathanos, and I am absolutely not writing that as a ship but it is popularly rumored and it is something on Sylvanas’s end, that Sylvanas is into humans and can’t shake that rumor.)
