And that's a wrap on Jonmartin Week 2026!

Thank you to everyone for participating however you could, whether that be by writing, doing art, or just following along with everyone's awesome work!

We will keep things open for a couple more days and accept any late submissions, but other that that, we hope to see you all back again next year!

Day 2 (Bands and the mechanisms) and 4 (HR volations) of @jonmartinweek , sorry it's late, but i had to do it!

Martin is implied to be watcging footage / looking through the door.

[hawkmothdiemotte]

Hr violations (they haven’t been taking their union demanded breaks and then fell asleep in the institute)

Ghosts and gender stuff in one (Jon is part of ghost hunt uk audio edition, Martin is wandering the halls of an abandoned office building) and faes (also with gender stuff cause fae)

Bonus: hyper-mobile jon (cause he like me frfr) with back and knee pain and using a cane

@jonmartinweek this will be my last one probably (i might add stuff or change out the pics for more rendered ones if i do continue but for now i just wanted my concepts out before its 2 weeks after jonmartin week, i dont have ideas for the other prompts/ am unhappy with my sketches so they might appear as well)

[mxwhore]

sliding in fashionably late for @jonmartinweek with "I Will Fall in Love with You" with a side of "When does a Man become a Monster?"

(I took some inspiration for this from the end of a fic I wrote. if you choose to read, please mind the tags.)

[hawkmothdiemotte]

Idk if that one was an epic ref but I made it into one @jonmartinweek

You could make arguments for either of them to be ody or penn but I think Jon seeing all the oceans and becoming a monster is the most fitting so voila!

[mossiistars]

I'm gonna do jonmartin week again this year, don't worry! The streak won't be broken! The pacing is just gonna be a little wonky, given how much of my time is taken up by college stuff atm :3

[mossiistars]

The plan: do everything tomorrow. This will surely actually happen and have no consequences

[mossiistars]

I'm sorry guys, I don't think I'm gonna be able to do more than just the three I already posted this year :( school is just taking up too much of my time

here are some of the brainstorming sketches I did while trying to figure out what to draw for the days, to make up for it.

[jonmartinweek]

Is it alright if I use the prompts here for other fandoms/OCs (with credit OFC)

I want to do a prompt week of my own and love these, I just don't like drawing Jon or Martin lmao.

It's great to hear that you're interested in running your own event. Community engagement is the lifeblood of fandom, so it's always exciting when someone wants to create and host a new prompt week.

Since it sounds like you aren't a fan of the ship, you're probably not familiar with how Jonmartin Week is run. Us mods don't come up with the prompts; they're sourced from participants in the event/fans of the ship. Prior to the event itself, we put out an open call for people to submit prompts they'd like to see in the next event, then we ask everyone to vote for their favourite submissions. The top 14 entries become the prompt list for the event (along with Ace Day and the Free/AU Day, which are standard every year).

All of that is to say, we don't 'own' the prompt list, so we can't really give you permission to use it; nor can we stop you from doing so. But it's probably not the best way to go about establishing your own event? The prompts may seem generic (particularly if you're not familiar with the source material), but they're actually pretty specific to these two characters. For example: 'I really loved you, you know' is a direct quote from Martin to Jon, and 'Apocalypse Road Trip' is a reference to their journey in the fifth season of the podcast.

Rather than re-using prompts that were directly inspired by this couple, wouldn't it make more sense to choose prompts that are specific to whatever fandom, ship or character you are actually interested in? Particularly if you're considering creating an event of your own; it would probably be best to try and generate interest and encourage participation early by allowing people to have a say in the prompts (similarly to how we generate our list each year).

If you're not interested in creating an event and just want permission to use the prompts to draw something every day for a week... why would you need our permission? Inspiration is free, it can come from anywhere; you can draw whatever you want...?

@jonmartinweek

Last year I got into the Magnus archives literally 1 week after jmart week just ended, so it was important to me that I contribute something since its been almost 1 year of tma for me !!

[jonmartinweek]

Just wanted to say an enormous and heartfelt thank you for the event, which has done such wonders for the creative juices! Looking forward to settling in over the weekend for a read and scroll of all the fabulous stuff that’s come out of it :)

@jonmartinweek day 4: HR violations (in more ways than one!)

[late-to-the-magnus-archives]

Fair: a Magnus Archives fic

There’s a ghost in the attic in Somewhere Else. It scared Martin.

That will not do.

A short story for @jonmartinweek2026 with the prompt, "Gender Diversity // Hauntings & Ghosts."

This takes place after the events of MAG200. They are safely Somewhere Else. They're happy and together and there are good cows don't ask too many questions.

Do mind the tags.

———

The ghost appeared at the toll of the midnight bells in St. Patrick (which was irritating because Jon knew for a fact that the bell was forty-six seconds off), hovering in the middle of the chandelier and yelling at them. 

It had been honestly absurd. Ridiculous enough (especially after all they’d seen) that Jon didn’t even react right away. He gave it almost no attention. It was sort of funny? But also irritating?

“Doom!” proclaimed the ghost in detail.

“Oh, good Lord,” he mumbled into his pillow. “That’s all very nice, threatening to remove our skin one tweezer-pinch at a time, but we aren’t interested."

"You," snarled the ghost.

Jon had enough. "Go away.” He hadn’t really meant to make that a push, to say those words with power, but it happened. Maybe that was why the ghost did go away, vanished in a blink.

Peace at last! 

Though honestly, if he’d realized how frightened Martin would be by this, he’d have done a lot more than that.

#

Unfortunately, the morning brought confusion.

“You’re not listening to me. You never listen!”

“I am listening! You’re not making sense.”

“I’m not… look. I have eyes. I’m telling you, it’s him. He’s here.”

Jon sighed. “And I’m telling you that the ghosts aren’t even real, and that couldn’t have been Jonah.”

Martin flung his hands in the air. “I saw Jonah.”

“Martin…“

“Never mind. You’ll see eventually. Or I will, I suppose,” Martin muttered, and turned to pour the tea.

Jon hunched. Arguments were so rare between them that he’d built up no immunity, and he felt sick. “I’m sorry.”

“Don’t.”

“I didn’t really look—“

“And you’re probably right.” Martin sighed and sat, placing fine bone china teacups before them both. “I’m sorry to insist. I know between us who has the better set of peepers.”

“Peepers!”

“But it was Jonah, and he said such horrible things."

“I heard those words,” said Jon slowly. "I didn't look at it very closely. At least it went away when I told her to."

“Can a ghost possess another ghost, maybe?” said Martin.

Jon couldn't take that question seriously. His smile felt slow and warm, a gentle cascade of molasses. “You ought to have the answer to that, seeing as you are one.”

Martin snorted. Martin laughed. Martin leaned over their tea and kissed him while steam caressed the undersides of their chins. “What am I going to do with you?”

Jon kissed him back. “Putting up with me is a saint’s burden.”

Martin rolled his eyes. “Can you make the ghost go away again?”

“I’m not sure, but it can’t hurt us, you know. It’s a remnant. A fragment of memory. It’s tied to the End, whatever it is, whoever it was, and it has no power beyond trying to frighten you.”

“Well, bully for it, then,” Martin mumbled.

Jon cupped Martin’s hand and brought it to his lips. “It will be all right. I’m hardly in the business of letting harm come to you.”

“How can you say that, Jon?” said Martin, high and sweet and scared.

“Because I am going to go talk to the ghost and come to an agreement. Or else.”

“Or else?”

“I suppose we’ll see if I can still destroy that which is seen.”

Martin shivered delicately and flushed at the suggestion, then cleared his throat. “Or maybe we could just move?” he said, grinning crookedly.

“Ha.” Jon kissed him, then held him, trying to calm his shivers. “Trust me.”

It was a choice. There were reasons for both paths from that request, but Martin chosen the happier one. “I do.”

#

The attic floor creaked under his feet. He ignored it. Sounds weren’t important here; sight was. Also the inalienable truth that he should have come up here sooner because the place was full of unreal webs.

Just full, walls hidden, like some absolute twat had decided the Sims-Blackwood household needed more subtle guidance.

He wouldn’t even pretend that didn’t piss him the hell off. “I know you’re here,” he said, standing in the attic’s center, arms crossed. Webs (real and otherwise) fluttered above his head, on all sides, and stuck to the sleeve of his sweater. “This has all been quite irritating, I’ll have you know. Show yourself.”

The house creaked once, as if in distant and antiquated refusal.

Oh, fuck that. “You won’t like how it feels if I have to expose you instead.” To make his point, he stared right at the ghost, right at the place where webs and shadow formed a hint of nothing, produced an urge to turn away.

A shimmer announced the ghost’s existence, and then, there it was. It wore long, heavy black, cinched frighteningly tight at the waist and balanced by puffy black sleeves. Its hair was severe, tied back, and its eyes were black, sharp coals. “I’m here. I suppose you’re happy now. Well, you won’t be when I’m through.”

Jon frowned, squinting. Now that he wasn’t half asleep, the situations was more obvious. That did change things. "What do you want, anyway? It’s not like I can give you the world again on a silver platter.”

A pause full of heavy things, none of them kin to guilt. “So you can see who I truly am.”

"Of course. I can’t say I’m sorry for stabbing you.”

The ghost bared its teeth. “I wouldn’t expect you to be.”

“Did you choose a man the first time you stole a body?” Jon said conversationally, taking a step closer. “Or did you have to build up confidence over time to be yourself?”

Another pause, shock joining the heaviness, and Jonah hunched. “I never used a woman’s body. Why would I? Damn you, damn you, this is your fault!”

Jon made a face. “For heaven's sake. You’re blaming me for your afterlife?”

The ghost growled.

Jon had a choice. Here Jonah was, evidently tied to the man who'd murdered him, condemned to watch neurodivergent queer domestic bliss for the rest of his death. Trapped, the way Jon and Tim and Sasha and all of them had been. It was wildly fitting.

But the rest of this was not punishment. It was wrong. “Is this how you prefer to appear?”

The ghost snarled at him. “Of course not!”

“You just woke up this way, I suppose?”

“Woke up? Woke up? I am dead.”

“Yes, and I still don’t regret that,” said Jon, studying every inch, scouring every angle, ignoring the slight green tint the air took on as he stared intoaroundthrough Jonah Magnus. “I think your memories influenced this condition. At any rate, we’ll need to lay some ground rules.”

Jonah sputtered. “Ground roles? Have you lost your mind?”

“Probably,” said Jon, and took a step closer.“I have quite a few questions, so I’d say honest answers from you will be part of the bargain.”

“The bargain—”

“Quite frankly, I’m not even sure how I managed to drag a ghost with me to a different world,” said Jon. “There’s no one from the End here to ask, alas. Well. Anyway. Would you prefer your previous form? Elias’s, I mean.”

Jonah was briefly struck dumb. “What are you saying? You couldn’t possibly resurrect me. I’m sure of it.”

Jon shuddered delicately. “Nor would I try. Ugh. You will remain deceased.”

Jonah growled.

“Yes or no?” said Jon.

The words came out in a growl. “Compared to this? Of course. Elias is as good as any, but apparently, I am instead forced into face and form I spent decades surpassing, trapped in a visage I fought to eschew, and that is my damnation, that is my penally, that is my personal torme—” Jonah’s voice dropped an octave, cut of the last word, and ended in a gurgle. Jonah grabbed his crotch through the dress and grunted.

Jon put his hands in his pockets. “That ought to do it, don’t you think?”

Jonah pulled open the dress and stared down at himself. “What? How?”

Jon sighed.“Focus, please. Regarding our deal: point one is the honest answers, as discussed. Point two is this: you will leave us alone unless invited.”

Jonah was busy investigating himself, reaching up under the skirt, patting his chest.

“I can’t have you running amok,” said Jon. “You’ve frightened Martin, which I must inform you will not be repeated unless you’d like to learn what personal torment truly is.”

Jonah gawked at him. Ghost tears did not, apparently, pay heed to gravity, and floated around him to evaporate slowly like dying candles. “You… how did you…”

“I see you.” Jon spoke and Jon did not speak and It spoke and they spoke as one. “Once you’re seen, you can’t be hidden anymore. I have to be quite careful with it; not everyone wants to, ah… what is the phrase? ‘Live their truth.’”

Jonah stared again.

“No more frightening Martin,” said Jon. “That is non-negotiable.”

Jonah visibly struggled to parse what was happening. His mouth opened and closed; a ladybug flew through his head to perch on the wall behind him. “I… all… all right.” Jonah wiped at his face. “I agree to your terms. But why? Wh…Why did you do this?”

“Lies will hardly do us any good, will they?” Jon said, slightly tetchy. “Besides, it’s only fair.”

”Life is not fair,” snarled Jonah.

”Which makes it more important that we choose to be,” Jon said, irritated. “That’s who you are, never mind how you were born. Anyway. I’ll talk to Martin. I doubt he’ll want to see you for some time, so you’ll need be on your best behavior. If you must wander, don’t bother us. All right?”

Jonah clutched the front of his dress, misshapen now that he had no breasts to fill it. “I owe you now. So very much. This rage must surely burn, and yet I owe you so much.”

“So dramatic.” Jon wiped off some spiderweb, made a face, and turned to go, then paused, hand on the attic hatch. “I don’t know who of the Web is involved in this or why—mostly because I have no desire to look and involve myself—but if you don’t get out of my house, I will see you.” He looked up, the air around him once again tinting green. “And I will burn you.”

No one said anything as he climbed back down.

Martin stood in the kitchen, wringing his hands. “What happened?”

“All is well.” Jon slid his arms under Martin’s and kissed his chin.

“So it… it’s gone?”

“Well, you were right, and I have to admit it,” said Jon. “It’s Jonah.”

Martin stared. “He was? He was! I was right!”

“I’m sorry I didn’t listen,” Jon said fondly, stroking his hair.

“As you should be," Martin teased loftily, then grinned. "So what happened? Did you blow him up?”

“No, I didn’t blow him up," Jon said, grinning back, "but we came to an agreement. He won’t be bothering us with an invitation. We need to determine how to deal with him. I think he's trapped.”

”For certain?”

”For certain.”

”Good. I hope he hates every second,” said Martin with that sweet murderousness Jon couldn’t help but find adorable.

Jon took his hand. “Shall we do that shopping?”

“The groceries won’t deliver themselves,” Martin agreed as they donned their shoes and headed out the door.

Just once, Jon glanced back.

Jonah stood in the attic window, his dark suit miraculously tailored, his face twisted with a bizarre mix of hate and gratitude too deep to name.

Oh, dear. Well. That would work out however it did. At any rate, no one would be scaring Martin anymore, and that was all that mattered. “Tell me if you see any good cake.”

“The one with the strawberries?” Martin grinned.

“Of course the one with the strawberries,” said Jon, and together, always together, they went on with the rest of their lives.
