Two for One - Crossover and Fusion Mini-Challenge

[mimihylea]

Two for One is an annual mini-challenge to help people who like crossovers and/or fusions find one another's requests.

To participate, simply copy-paste the following into a comment:
AO3 Name:
Letter Link:
Crossover Type: (ie. crossover, fusion, or either)
Applicable Requested Fandoms:
Potential Crossover Fandoms: (you may list specific combinations you're interested in, ex. Megamind/Treasure Planet, or generally request any of your Yuletide requests with each other, or list additional fandoms you'd be happy to have crossed with any of your requests)
Prompts/Optional Details: (as many and as detailed as you like)

One of the fandoms in each crossover or fusion prompt must be one you are requesting for Yuletide; however, the other doesn’t have to be. It doesn’t even have to be in the tagset at all!

Some clarification about crossover types:
Crossovers tend to involve Fandom A's characters interacting with Fandom B's characters or worldbuilding, with everyone retaining their canon backgrounds. Ex. Aurora and Red Riding Hood team up to defeat a villain, or Clark Kent falls into a portal that takes him to Tortall.

Fusions tend to be AUs in which Fandom A's characters have always existed in Fandom B's setting instead of their own, often replacing Fandom B's characters. Ex. Pacha and Kronk as contestants in the Hunger Games, where Kuzco and Yzma are referees. (A fic like this in which Hunger Games characters also appear would be a hybrid between a fusion and crossover.)

AO3 Name: astrokath
Letter Link: my letter (https://trisigmatic.wordpress.com/2025/10/18/dear-yulegoat-2025/)
Crossover Type: either
Applicable Requested Fandoms:
[1] The Laundry Files - Charles Stross/Slow Horses
[2] Blood on the Clocktower/Machineries of Empire - Yoon Ha Lee

Prompts/Optional Details:
[1] I’d be very open to a Slow Horses crossover with my Laundry Files request. Either in the general sense of keeping incompetent practitioners away from civvy street, or cameos by the Slough House team. Roddy Ho has surely run into algorithmic things that mortal man wasn’t meant to know. Was he just too oblivious to worry about? How do the Laundry and Slough House teams end up tripping over each others’ feet? Is Lamb a Deeply Scary Sorcerer on secondment? Are Catherine and Mo colleagues who bond over the trials of being in/heading towards middle age?
[2] I requested both of these fandoms, and the obvious prompt is: hexarchate characters play Blood on the Clocktower. Calendrical effects ensue.
