Dimileth Spring Fever is just under a month away, Friday May 15 through Sunday May 17!
In honor of the occasion we've revitalized some old promo graphics helpfully made by mod A's spouse.
I wrote a raffle prize for the #DimilethExchange comment raffle and I am so delighted to have gotten to write for the amazing @bay115.bsky.social! This was an adorable request and I hope you like my take on the Dimileth family.

Fem Byleth and Dimitri posing in front of the Azure Moon movie poster and on the red carpet. Byleth is wearing a black corset and a long glittering skirt, her arms are covered by a mesh bolero. Byleth has tied her hair in a side ponytail. Dimitri is wearing a black turtleneck over a gray corset, a blue belt with a lion buckle, black pants and blue glittering shoes, he's also wearing a long blue cape with fur. There's a little sketch of Byleth saying that she dyed a strip of hair green in honour of her character in the movie.

Late, but I wrote some smutty semi-public omegaverse for JustWantSauce for the #DimilethExchange! Dimileth make terrible decisions at an opera. archiveofourown.org/works/79400041
Watchfulness dpsisquared Summary: Jeralt sometimes joked that her eyes had grown so large because she was always looking, watching, absorbing the details of the world around her like a sponge. Words could be twisted, honeyed, and misleading, but bodies and actions couldn’t lie. Byleth got all the information she needed about someone from observing them, so, efficient as she was, she simply skipped the talking part. Byleth's eyes have always been drawn to Dimitri. At Gronder Field, she can't believe what she sees.

He calls upon the Ashen Demon for their services (and discretion) to assassinate him. However, they have a specific condition that must be fulfilled to carry out Dimitri's request: the payment must be made in small amounts, spread over time and presented as a gift in front of Dimitri's confidantes and retainers.

Mother, Mother, Have I Boiled the Frog Enough? Rating: E When Lambert announces his sudden engagement to the elusive Byleth Eisner, Dimitri swallows her discomfort and resolves to be a good daughter, even if it means welcoming a stranger to the family. To her surprise, Byleth is pleasant, and Dimitri starts to see her as the mother she never had. The idea of Byleth being family soon becomes appealing. Until it all goes awry when Dimitri’s affections twist into something perverse.

our godforsaken right nebulia Summary: Byleth lets out a short, angry sigh. "Dimitri," they say, frustrated. Dimitri is almost bitterly satisfied with it, managing to drain Byleth's well of patience for him at last. "You are remarkably easy to love."
