First Yuletide Event Letter

[goatgodschild]

Hello, author(s) --

I always enjoy worldbuilding, and how you write this may be up to you -- full paragraphs on a specific topic, or a list of brief headcanons.
Please do not kill off the tagged characters.
Unhappy endings are not preferred, but bittersweet is fine.
Poly is not preferred. I don't hate it, but I don't especially like it, either.

My fandom requests are:
- Age of Fire
- Widowland
- True Detective (note: Marty and Rust slash, Marty subbing)
