Challenge 41

Posted by: matsushima

How has it been over a month since I last posted here? I'm so sorry. Life got away from me.

This week's challenge is:

General Prompt: Outrageous
Relationship Prompt: Apologize

Posting runs from now until the challenge roundup post next Sunday, August 1, 2026. More information here.

The Adopt-a-Prompt challenge is still open! This is different from a traditional amnesty because you can only choose prompts with zero fills and you should (ideally) claim your prompt in advance before posting.

iddyiddybangbang sign-ups are open and what's more idfic-y than fandom OCs?

[Prompts: Thought and Warm] Eternity's Floating Around and Around (TWST)

Sat, 16 May 2026 01:54:01 GMT

Posted by: haunted_cherries

Fandom: Twisted Wonderland
Characters: GRem Van der Zee (OC), Jade Leech (canon), Georgina Leech (canon), OC x Canon
Rating: Gen
Words: 940
Prompt: Thought and Warm for fandomocweekly
Summary: Floyd and Azul not coming home to see her is one thing, but Rem not coming, either? Unacceptable in Georgina Leech's eyes. Even worse for Rem that this trip will mean owning up to put off tasks.

Notes: WELP I had this in the drafts for a WHILE and figured I would bust it out for a Fandom OC Weekly amnesty prompt!! This is part 1 of a 2-part oneshot, so Please Look Forward to It...next time...maybe next month...who knows with the way my writing juju comes and goes. xD Anyways, ENJOY! ^ o^)/

****

"Oh I know, Mother, truly a tragedy. Floyd said that he was too bored to come, and Azul immediately shuddered at the thought," Jade feigned a sigh as regaled the tale to his mother on the other end of the phone. "I was sure at least Floyd would come, but alas."

Adopt-a-Prompt (Amnesty)

Sun, 26 Apr 2026 10:11:41 GMT

Posted by: matsushima

For the duration of 3weeks4dreamwidth (April 25-May 15), we're doing a special kind of amnesty: adopt-a-prompt!

There have been many prompts posted that don't have a fill. Claim one here and post by May 15th whenever you get around to it.

Please only claim one prompt at a time. Once you've posted one fill, you can claim another. (It makes my life easier if you reply to your claim with a link to your fill. Thanks!)

Fills for this challenge so far:

Eternity's Floating Around and Around (TWST)
