Castle Ficathon Winter 2025

CastleFicPromoter’s Castle Ficathon Winter 2025

Hello and welcome!

This post is to announce a fun way that the Castle fandom and its talented fan fiction writers can generate some awesome stories over the winter holiday season of 2025/2026, keeping our shared love for Caskett alive.

Participating stories should be posted on Fanfiction.net or Archive Of Our Own (but please, let me know if you are only posting on AO3, as I don’t have a way to get notifications if you do). Stories posted on FFnet will be included in the “favorites” list on the CastleFicPromoter FFnet account. Links will also be tweeted through our twitter account and blogged/reblogged on tumblr, as well as bluesky.

Rules: Since the holidays are a busy time, the word goal will be set to 30,000 words to achieve the Ficathon. To achieve the Mini-Ficathon you’ll need to break 15,000 words. To achieve the Maxi-Ficathon, aim for a word count of 50,000 words. For the really adventurous, Ultra-Ficathon word count is set at 75,000 words.

Word Count Goals:

Mini-Ficathon – 15,000 words Ficathon – 30,000 words Maxi-Ficathon – 50,000 words Ultra-Ficathon - 75,000 words

Submissions will be accepted starting Friday, November 28, 2025 and ending at midnight (US Pacific) on Friday, March 6, 2026. You can start writing at any time, but only fanfics posted within the time frame will be accepted as part of the Winter Ficathon. Before then, plot and plan away.

Anyone can join, experienced and new fan fiction writers alike. The main point is to have fun!

Stories are to be posted on your own FFnet account/AO3 account, but should have “Castle Ficathon Winter 2025” somewhere in the summary, so that readers can know that the story is a participant. Also, if you post a link to the story on Twitter/X, make sure you tag @CFPromoter in your post, so I’m aware you’ve started posting and I’ll generate a promo tweet for it.

I’ll be using the hashtag “CastleFicathonWinter2025” on Twitter/X and bluesky when I do promo tweets. Also on tumblr, please use the tag “CastleFicathonWinter2025” for ease of reblogging.  I’ll also be using the hashtag “CFW2025” on tumblr and Twitter/X and bluesky.

Need help coming up with story ideas? Feel free to check out the prompt list on our tumblr page, or the many prompts to be found on the Castle Fanfic Prompts tumblr.

Every participant will receive an individualized digital badge of participation at the end of the challenge. Participants will also receive an additional badge for the word count level achieved at the end of Ficathon. Those who reach or break 50k will also receive a personalized wallpaper based off the Castle Ficathon Winter 2025 key art.

Don’t stress if you have trouble with updating regularly, the main point is to have fun, so… no pressure.
