Croquis et Agaceries d'un gros bonhomme en bois (Sketches and exasperations of a big wooden dummy)
by @monocostrap / @hanarinhightown ※ Ao3: monocostrap (hanarinhightown)
Clair Obscur: Expedition 33 ※ Painted Verso Dessendre & Monoco, Painted Verso Dessendre/Monoco, Painted Verso Dessendre & Esquie ※ 3,599 words ※ Teen And Up Audiences
Summary:
Verso needs to find Soarrie. He knows they will need it in the days to come, but he's not prepared for the expeditioners to learn they have options. So he slips off in secret, enlisting the help of the only one that, at the end of the day, he can trust: Monoco. The two venture to their old home in Frozen Hearts to find the rock and reminisce about days gone by...
But they might not get through it without having to talk about the Sakapatate in the room.

Innocent Curiosity
by Hel_Be_Praised ※ Ao3: hel-be-praised / Bsky: helbepraised.bsky.social
The Shape of Water ※ The Asset/Elisa Esposito ※ 2,768 words ※ Explicit
Summary:
Exploring what they could do together was only natural. Elisa was in awe of his body. Of the graceful, petal like protrusions of his gills when he breathed. He seemed to her, larger than life. Something that had stepped out of a fairy tale. How could she not want to touch him? How could she not want to feel the press of his firm body against hers? How could she not want to feel the rough texture of his skin as it caught and dragged against hers deliciously?

D'un cahier d'esquisses // From a Sketchbook
by @monocostrap / @hanarinhightown ※ Ao3: monocostrap (hanarinhightown)
Clair Obscur: Expedition 33 ※ Painted Verso Dessendre/Mask Keeper, Original Verso Dessendre/Gustave ※ 5,143 words ※ Explicit
Summary:
'Verso shifted his feet on the cool stone, as if testing the weight of his body against the painted illusion of gravity. No, he didn’t have answers. He didn’t know where Verso Dessendre ended and he began, and he suspected the only way he could approximate an answer—the only way he could regain his waning resolve in the Dessendre war—was to face this other image of him. A simple equation, to see if anything remains, like a piano reduction of a vast symphony. Would it resonate? Or would they cancel one another out?
The Mask Keeper, with their towering body of iron, took a fluid step toward Verso, the void of the mask indifferent once more.
“Tell me, Verso Dessendre: When you peer into a looking glass… What do you see?”
Verso clenched his jaw, refusing to meet the nearest mirror. “I see myself.”
“Do you?” The Mask Keeper’s tone sharpened like a blade. “Or do you see a collection of brushstrokes? An echo pretending to be a man?”'
The creators in the 2024 Fiends & Fangs Fanwork Exchange are now revealed! 🎉
Check out their works in Fiends and Fangs Fanwork Exchange 2025 Works and shower these wonderful, talented folks with love!!
MANY thanks to everyone who participated in this year's exchange! You all are amazing, and we can't thank you enough for participating and contributing your monster masterpieces ❤️
Come join us in the Fiends & Fangs Discord to hang out and love monsters together!
Hello, monster lovers! In light of Fanwork Reveals getting pushed back a day, thus leaving less than a week for everyone to enjoy the collection while authors are anonymous, we have decided to also push back Creator Reveals by one day.
This will give folks more time to enjoy the outstanding works in the collection, as well as wrap up any anonymous treats (neither of which will be precluded by Creator Reveals, to be clear!).
The new date and time of Creator Reveals is now Sunday, October 19, 7PM Eastern.
See you then! In the meantime, check out the collection: Fiends and Fangs Fanwork Exchange 2025

Meanwhile, the mod team will be working on ensuring everyone gets their match made in monster heaven! We hope to have assignments out no later than Sunday, August 24, 2025 at 11:59pm Eastern.
Fiends and Fangs Fanwork Exchange Sign-ups are OPEN!
Sign-up period closes: Sunday, Aug 17 2025 at 11:59PM EDT
That's right, friends! Sign-ups are now OPEN!! 🎉🎉🎉

Sign-up Overview
In your sign-up, you are allotted a minimum of 2 and maximum of 8 requests and offers each. For each of your requests/offers, you can request/offer 1 fandom. Between those fandoms, you can request/offer up to 6 relationships (it'll make more sense once you're in the sign-up form). The breakdown is basically:
1 sign-up consists of at least 2 requests and 2 offers > each request and each offer consists of 1 fandom and at least 1 relationship within that fandom.
Please keep in mind the following:
You do not have to offer the same fandoms or relationships that you request.
Requests will be visible to anyone who can view the collection—this can help exchange participants come up with their offers, and it allows anyone, exchange participant or otherwise, to browse the requests for treats they may wish to create.
Offers will only be visible to the exchange mods. If there are any individuals you do not want to be matched with, indicate that in your offers, not in your requests, which everyone will see.
You may come back and edit your sign-up at any point until sign-ups close. So if you only know what pairings you want right now, but plan to return later to list prompts, Do Not Wants, etc., you can absolutely do so!
Decide if you're open to receiving "treats", which are extra fanworks people can create for you based on your requests. If you're open to treats, 1) make sure you've opted into them in your Ao3 profile (see FAQ: 4. Treats for instructions), and 2) state that you're open to treats in your Request Details.
How to Sign up for the Exchange
On the Fiends and Fangs Fanwork Exchange Collection page, in the left sidebar, click "Sign-up Form".
Requests
1. In the Requests section of the sign-up form, select 1 fandom, then select 1-6 relationships.
❗Note: The only relationships that will come up are those within the fandom you select, which narrows down the list of relationships to choose from.
2. Indicate if you are requesting fanfic and/or fanart by checking "Fanart" and/or "Fanfiction" in the Additional Tags field.
❗Note: If you select both fanfic and fanart, you are indicating that you'd be open to receiving either fanfic or fanart for any of your requested relationships. If you'd specifically prefer fanfic or fanart for any particular relationship(s), please indicate that in the Request Details; otherwise, we will assume you are okay with receiving either fanfic or fanart for all your relationships.
3. In the Request Details, indicate whether you're open to treats, and provide any information that might help your gifter create something you'll love—these can be specific prompts, your favorite tropes, etc. Most importantly, please state any "Do Not Wants" (DNWs)—things that you are not okay with someone incorporating into your gift.
❗Note: You can also provide a request letter, if you have one. A request letter is a completely optional write-up you can provide to the person who'll be creating your gift. It can contain more detailed prompts, OC descriptions, and anything else you'd like the person creating for you to know. You can find a basic template here: Dear Writer Template. You can find examples of Request Letters (also referred to as "Dear Creator" Letters) on Tumblr (Requests Letters don't have to be on Tumblr—you can put it in a Google Doc or other shareable application): "Dear Creator" Letter examples from Tumblr.
Your request might look something like this:
4. Repeat steps 1-3 for Request 2 and up to Request 8.
Offers
In the Offers section of the sign-up form, select 1 fandom, then select 1-6 relationships you're willing to create fanwork for.
❗Note: The only relationships that will come up are those within the fandom you select, which narrows down the list of relationships to choose from.
2. Indicate if you are offering fanfic and/or fanart by checking "Fanart" and/or "Fanfiction" in the Additional Tags field.
❗Note: If you select both fanfic and fanart, you are indicating that you're willing to create either fanfic or fanart for any of your offered relationships. If you'd specifically prefer to offer fanfic or fanart for any particular relationship(s), please indicate that in the Offer Details; otherwise, we will assume you are offering either fanfic or fanart for all your relationships.
3. In the Offer Details, you can indicate anyone you wish not to be paired with (remember, only the mods can see this portion of your sign-up).
4. Repeat steps 1-3 for Offer 2 and up to Offer 8.
