Hello, and welcome to the Dimension 20 Advent Calendar, a Dimension 20 fan event! This is a fanfiction writing event where participants can sign up to post fics from 1-24 Dec, with a different person posting their fic each day! FAQ below:

How many fics can one person write? One to start! It's going to be a different person posting their fic each day of the Advent Calendar. This will be coordinated via Discord (link below).

Can I write more than one fic if I want to? Double-ups will only open after every slot has been filled. Unless there aren't enough people signed up by a certain point, in which case yes.

What sign-up slots are available? Earlier days of the event will have shorter word count min/maxes, and later days of the event will have longer word count min/maxes. People will be able to pick and choose which day they'd like to write for.

Are there any guidelines for what I can/can't write? All fics MUST be SFW (if you wouldn't talk about it with your boss, don't turn it in!) and about Dimension 20. Your fic MUST also include the word "Christmas" in it. However, Christmas does not need to be the focus of the fic — it can be extremely relevant or incredibly tangential. :)

Can I submit fanart instead? Not as part of the event, but of course feel free to make fanart of your favourite fics that get posted :)
