FAQ:
What is Seblaine Sundays?
Just a cute little event where writers and creators post something relating to Seblaine on the last Sunday of each month! It can be fanfic, fanvids, edits, manips, art, poems, etc., so long as it's not plagiarised or AI generated!
Do I have to participate in all months?
Nope! You are free to pick and choose whichever prompt speaks out to you!
What if none of the prompts/a particular prompt doesn't speak out to me?
You are more than welcome to either swap it out with another month if you would like to post something sooner/later, use a free prompt wildcard, or an alternative prompt! We will be posting alternative ideas closer to the start of the event. It can also be a prompt that didn't quite make the cut in the polling!
Where was the polling?
On The Seblaine Archive Discord server! Please feel free to reach out if you would like a link to join! Our pinned post can give you more information about the server.
Do I have to be a part of the server to participate?
Nope! We will be active on this blog and provide information about the event as needed. The server is there to bring Seblaine fans together and provide an easier medium to chat, discuss, and so much more!
I'm not sure how to interpret this prompt.
Not to worry! At the beginning of each month, we will post some inspo pics and things to reference for some ideas!
Do I have to submit on those dates?
You are free to submit it whenever you're happy with it! The dates are just there to provide some sort of guideline and to keep in theme with the "Seblaine Sunday" schtick.
We will be creating a collection on AO3 closer to the event, and will be reblogging everything so long as we have been tagged in it!
Any other questions, please feel free to reach out. Happy creating!

June’s prompt is:
Summer Camp Slasher AU
Picture this: summer vacation, road trip up to the lake, the warmth of the sun beating down... Friendships, lovers, talks about the future, the world in your hands... when suddenly, someone drops dead, your phone has no service and, well, you know how the trope goes.
How can Seblaine survive this summer? Or, are they the one cutting ties with those who wronged them?

We are officially 1/4 through the year!! Oh, does time fly~
Welcome to March- a new month means a new prompt! For the original post, please check it out here!
March’s prompt is:
Virginity / First Time AU
This was a prompt voted in as our tie breaker on The Seblaine Archive, and it’s very fitting for our boys considering the episode they meet is called The First Time! Who knew that fateful encounter would lead us all to loving these boys so many years on?!
This can of course, be interpreted in any way you like! Whether it’s them talking about how their first time should go, their actual first time together, or first time doing anything at all, the prompt is your oyster!

Just a reminder if you wanna join us this month for the Seblaine February prompt!
The prompt is SOULMATES, so if you’re a writer, a video editor, and artist or just someone who loves these guys as much as we do, you’re so welcome!
So, you don’t necessarily have to post on February 22nd. You have the rest of the month, since well, the whole month it’s been declared SEBLAININTINE! 💕
There’s many ways you can participate, not just creating. And please don’t forget, this ship, the characters, the actors behind them, is ALL about LOVE,
Oh? It's already February? You know what that means...
It's the month of looooooove~ and The Seblaine Archive's next prompt! For the original post, please check it out here!
February's prompt is:
Soulmates
I know it. You know it. And I'm sure deep deep down, they know it. They're just simply meant to be! How can they not be when Sebastian was made for Blaine and Blaine is everything Sebastian's looking for in a partner?
So, to them, the soulmates! This can be interpreted however you like! Whether it's the red string of fate, their name on each other's wrists, or even following canon (😈), please bring joy by creating something to showcase their soulmateism!

Are you the same people who run the Kurtbastian archive?
No, we are not affiliated with that server. The name is a coincidence.
We archive Seblaine fanfiction directly onto our server like a library for members to search through via keywords, and the channels are organised by rating and completion status, hence the name The Seblaine Archive. We also have a direct RSS-feed to let the server know whenever there is a new Seblaine fanfic from AO3.
We are a very active server, and there is a lot more to it, but we are an archive first and foremost, and very community driven, so if you are interested, please join us!

An Archive of Our Own, a project of the Organization for Transformative Works
Bound by magic, blood, and a promise made too young, Blaine Anderson and Sebastian Smythe grow up on opposite sides of a war that was never meant to spare them. In a world where loyalty is lethal and love is a liability, they choose each other anyway. This is a story about devotion that defies families, vows stronger than fate, and a love that dares the dark to try and break it.
Notes:
A bit late, but this is my contribution to this month’s prompt for Seblaine Sundays! An event created by @theseblainearchive You can follow us and look forward to more content and events ✨
So this ended up being my mix of Seblaine, a touch of Romeo and Juliet–style tragedy, and the inspiration the wizarding world always brings me.
