Fandoms
Harry Potter (Dumbledore/Grindelwald)
The potential this pairing has is fascinating to me, and I'd love to see any kind of fic about them, either when they were young, or later during the war. I'd also really like to see an AU where they stayed together or made up later and ended up teaching at Hogwarts together/travelling the world/taking over the world. (Fic exploring what could have happened if Dumbledore had continued down that 'For the Greater Good' path would be especially awesome.)
Stargate (Sam/Janet)
I love Sam, and her relationship with Janet is one of my favourites. I could easily see their friendship leading to more, and I really like how they support each other in canon, and how Sam's kind of like a second mother to Cassandra. I'd love a hurt/comfort fic where Sam gets hurt on some mission and Janet looks after her, or the two of them relaxing together on a day off, or a fix-it where Janet doesn't die or comes back from the dead. Appearances from the rest of SG-1 would be great too, if you're so inclined.
Star Trek AOS (Spock&Spock Prime, Kirk Prime/Spock Prime)
Spock&Spock Prime: I really like the idea of the two of them being friends and Spock Prime acting as a mentor to his younger self. I'd like to see them staying in contact and Spock Prime offering advice (within reason) about the crew, his father, etc, and/or comfort over the loss of Vulcan. Background Kirk/Spock (either universe) is fine, but please no other relationships.
Kirk Prime/Spock Prime: Ah, my OTP. I'd love something with Kirk Prime ending up in the AOS universe somehow, but if you want to go with canon and just have Spock Prime remembering their relationship, that'd be fine too.
Notes: If possible, I'd prefer no references to the events of STID.
Star Trek TNG (Riker/Troi)
Definitely my favourite relationship in this series. I love their friendship, and I love them even more as a romantic couple. I'd enjoy seeing them on shore leave, or interacting with their friends, or backstory about the two of them before they started working on the Enterprise, or anything exploring Troi's empathic abilities and how they affect their relationship.
Star Trek TOS (Kirk/Spock, Kirk&Spock, Scotty/Uhura, Spock&Sybok, Spock&Saavik, Saavik/David Marcus, Kirk&David Marcus)
Kirk/Spock, Kirk&Spock: I'm listing these together because I honestly don't care which I get. I love Kirk and Spock's relationship in all its forms, so as long as it's about them I'll be happy. Generally I prefer gen set during the series and slash set during the movies, but I'm pretty flexible so don't feel you have to stick to that if you have an idea that conflicts. For ideas, I like pretty much the same things in slash as in gen - shore leave, the two of them stranded on a planet, one of them being hurt or ill and the other taking care of them, or any kind of fic dealing with the events of the episodes/movies.
Scotty/Uhura: Their scenes together in The Final Frontier are adorable. I'd love something set when they're older, but something during the series would be great too. I'd like to see them bonding over music, or going on shore leave together, or meeting each other's families, or anything really. I love this ship, and there just isn't enough of it.
Spock&Sybok: This relationship has always fascinated me. I'd love to see something set when they were young, with Sybok defending Spock from bullies, or Spock's reaction to Sybok's banishment, or an AU where Sybok survives the events of the film and they have to deal with everything that happened.
Spock&Saavik: I really like the little glimpses we get of their relationship in the films, how Spock is a mentor to Saavik and how they clearly care about each other a lot. I'd love to see more of this, maybe something set while Saavik is at the academy, or what happened after we last saw her in The Voyage Home? (Or, if you're so inclined, what she thinks of his relationship with Kirk?)
Saavik/David: My rarest rarepair. I really like their interactions in The Search for Spock, and I'd love an AU where David doesn't die, but I'd also be happy with something exploring their time together on the Grissom, or them getting to know each other, or him comforting her after Spock's death.
Kirk&David: The scene in The Wrath of Khan where David says he's proud to be Kirk's son is one of my favourites, and it always seemed sad to me that Kirk never really got to know David, especially since he loses him so soon after finding him again. As above I'd love an AU where David doesn't die, but any kind of father-son bonding between them would be great.
Notes: Since I know there are arguments about it, I take Vulcan body temperature as higher than human.
I think that's everything, but feel free to check out my past exchange letters if you want to know more. Thanks again!
