Dimileth Fever

An account for Dimileth 18+ seasonal events!



The following rules apply to all events run on this account:

  • You must be 18+ to participate

  • Tag your content appropriately and accurately


Is this just for F!Dimileth or M!Dimileth?
All versions of Dimileth are welcome for every event run on this account. If it involves Dimitri and Byleth, you're good.
We know that some people prefer a specific Byleth, so to help others find the content they want to see, consider using the Japanese and Korean tags as well for artwork. This will also help the JP and KR fandom find your art!The Japanese and Korean tags are:

  • ディミレス, 디미레스 (fdimileth, Dimitri/F!Byleth with any dynamic)

  • レスディミ, 레스디미 (fdimileth, Dimitri/F!Byleth with F!Byleth more dominant - first tags are also commonly used)

  • ディミレト, 디미레트 (mdimileth, Dimitri/M!Byleth with Dimitri more dominant)

  • レトディミ, 레트디미 (mdimileth, Dimitri/M!Byleth with M!Byleth more dominant)

  • ディミベレ (any Dimileth - very rarely used but if you want a tag that doesn't imply gender for Byleth, this is the best bet)

Polyships containing Dimitri and Byleth are also welcome so long as Dimitri/Byleth is a focus and not a side note. We won't be holding up a ruler to content submitted in good faith, but if you have questions on whether something would qualify, feel free to reach out.


Are events NSFW only?
Some prompts are explicitly NSFW, so you must be 18+ to participate, but we welcome both SFW and NSFW content!


How do I participate?
Make some Dimileth content inspired by the prompts, and tweet it with the event's tag during the event period! You can also add content to the AO3 collection, which will be provided for each event.
We’re also happy to retweet your WIPs for the event if you @ us!


What types of content are allowed?
Fic and art are the most common, but things like cosplay, video/audio content, mood boards, and crafts are also welcome!


What if I don't have a Twitter, or am not comfortable tweeting my content?
If you DM us or send us an email at [email protected], we'd be happy to tweet your content for you.


What if I’m late?
No worries! We'll keep checking the event tag for a month after the event ends and are happy to retweet anything new.
(For Hot Flash events, we only check the tag for a day or two since the premise is to see what you can do with a prompt in a short period...but if you were busy during the event and still want to take your own quick and messy shot at the prompt, @ us.)
