Rules and Guidelines

What is a Big Bang?

A Big Bang is a challenge where writers and artists come together to create an explosion of new content for a particular ship. The first Big Bang was hosted in 2005 for the Drarry ship.

Rules

All participants must be 18+ to participate. Anyone found to be misrepresenting their age will be barred from this event and all future events. There are no content restrictions for the event; dead dove content is allowed. No AI may be used in either your fic or art submissions. Anyone found to be using AI will be barred from this event and all future events.

Author Requirements

All fics must center the m/m Harry Potter / Tom Riddle | Voldemort ship. If you are in any doubt at all about whether your fic is 'Tomarrymort-centric' or would like further clarification, please do ask early. Email us at tomarrymortbigbang [at] gmail.com. The minimum word count is 10,000 words. All fics must be standalone and previously unpublished, written in English, and 100% written by you. Please use a beta for SPAG, or plan to be your own beta. NO AI-assisted editing OR AI-assisted translation is permitted. There will be a mid-point check-in on September 30, at which point authors are expected to be 30% of the way to the word count minimum and will submit a summary and snippet in order to match to an artist. Submissions are due on December 31 (Tom's birthday). (Optional) Theme: There is no formal theme for this event, but if you'd like a couple of ideas for inspiration, feel free to use 'Birthday Gifts' and/or 'Fast Burn' as your theme.

Artist Requirements

All art must center the Harry Potter / Tom Riddle | Voldemort ship, and correspond to the paired fic. Artwork should be polished and complete (ie, more than a sketch). Submissions do not all have to be in full color, but should at least feature clean linework with thoughtful shading and composition. Artists will be contacted to request matches after fic summaries are due on September 30. Artists and authors pairings will be released on October 15. Submissions are due on December 31 (Tom's birthday).

Why 10,000 words?

HP fandom Big Bangs have ranged from 2,000 word minimums to 50,000 word minimums. As an example, Drarry Big Bang was 50,000 word minimum (source), Jegulus Big Bang was 20,000 word minimum (source), Remus/Sirius Big Bang was 20,000 word minimum (source). For the Tomarrymort Big Bang, writers will have between July 31 and December 31 which is 5 months to complete 10,000 words. Please only sign up for the fest if you can commit to this minimum word count.

Sigh No More

by houndsofheaven

written for @tomarrymortbigbang 2025

Tom Riddle/Harry Potter, rated E, timeline mashup, BWL Tom Riddle

summary:

When the Dark Lord Grindelwald heard a prophecy that an “heir to the Hallows” would be his downfall, he sought to kill a mere infant—a boy named Tom Riddle. He failed, vanishing in the aftermath and leaving only a scar upon the child’s face.

Tom Riddle grew up unaware of the true nature of his significance, yet certain of its existence. When he finally learns that he is as extraordinary as he always believed himself to be, he is thrilled.

But complications lie ahead. Is Tom Riddle truly the sort of boy who could ever become a hero?

And then there is the small matter of Harry Potter, who is inescapable in any universe.

Chapter One Now Posted on AO3!

The Apprentice

Written for @tomarrymortbigbang

52k, M, 1/1

Harrymort, Dark Harry Potter, Death Eater Harry Potter, Dead Dove: Do Not Eat, Graphic depictions of violence, Master/Apprentice

After Harry found out who "Moody" really was and spent the year learning Dark Arts under the guise of preparing for the Tournament, he assisted Voldemort in regaining his body. As a show of good will, Voldemort offered Harry to become his apprentice, but Harry declined and agreed on an agreement of neutrality. Yet his own forays into Dark Arts led nowhere without a proper guidance and Harry approached Voldemort to see if the previous offer was still valid. Harry was tested. Harry was Marked. This is the fallout.

And with amazing art by @ galerides ! She doesn't have tumblr or other socials, so i'm posting for her.

Look at it, it's so awesome T^T <3

[ostensiblehare]

Super excited to share my artist submission for @tomarrymortbigbang 2025!

In collaboration with the wonderful @isalisewrites for her new work, Twilight's Radiance.

This has been such a fun project to do and getting to know such a lovely and talented writer was the best part (and getting first viewing of this incredible fic was certainly the cherry on top! 😉)

Magical backlash of Voldemort's attack transfers Harry across time to the night Tom is left at the steps of the Wool's Orphanage. They look so alike, their names sounding like they could be sons from the same family, so when the matron finds them, the logical conclusion is that they are twins. Harry and Tom grew up inseparable and possessive. They share everything. They have their secret language to speak in while no one is listening. Harry is empathic with fierce urge to protect Tom. Tom is colder, but he is ready to do anything for Harry. He will burn the world for him, he vows in the darkness of the night as they lie under a shared blanket. For them, it's only natural their relationship develops into a romantic one with time. To them, it's more than natural when they figure out they are descendants of the Gaunt family. It's like a continuation of family traditions, right? To everyone else… Well, it's a good thing they don't matter.

Also, the bath scene is my ultimate favourite thing of the whole fic and it is on the first chapter!

“The Wizarding World wanted a hero – they still talked about the symbol the child was, how Dumbledore was sure to be raising him to be the perfect Gryffindor, how this whisp of a thing would, if ever needed, be their savior again, and Voldemort felt great happiness then.

He’d take it all away, he’d break their faith, he’d leave them with nothing but regret, pain and misery. Shame and hatred and mistrust in their highest regarded member.

He’d destroy Dumbledore and The-Boy-Who-Lived in one single master stroke of genius.

For Lord Voldemort would, once again, be brilliant, and charming, and beautiful and complete – after all, even if his soul now resided also in a tiny child, it would always be close by.

He would make sure of it.”

Devil Devil

Exile. A lonely existence. Except for the fleeting company of one Tom Riddle.

Voldemort has won the war. And Harry is his, prisoner, horcrux. And Lord Voldemort will do anything to keep Harry as his.

Tomarrymort Big Bang 2025

Since @tomarrymortbigbang has given us permission to share summaries and/or snippets for our Tomarrymort Big Bang 2025 submission, I thought I'd share the summary of what I've been working on for the past few months.

Coming December 31st, 2025: Twilight's Radiance

Harry Potter fails to die. “Behold The Boy Who Lived, your precious chosen one, your supposed hero… in shackles.” Lord Voldemort reigns supreme. With the afterlife refusing to keep his soul and his freedom stolen by Voldemort, Harry must navigate the delicate tightrope between willful resistance and lives of his friends. What if he refuses Voldemort’s demands too much? What if precious lives are taken from him because he didn’t give into Voldemort? “What if I’m doing this all wrong?” Yet… something greater calls their attention. The Master of Death has not been seen for a thousand years and the dead are restless. And magic demands the restoration of the balance between birth and death Neither the light nor the dark can be seen without the other.

And in usual fashion, I have a chart. xD Because, apparently, this is becoming a habit of mine for all of my fics now. Arc Two and Arc Three are still in major development, so take what you see there with a grain of salt.

[tomarrymortbigbang]

Author and Artist Match emails have been sent out! 🎉

We had 32 unique fics to pair with 26 artists, so thank you to all the artists who volunteered to be paired with more than one fic, in order to help us ensure each fic would receive a match.

Please email us if you did not receive a match from us by this point.

Posting instructions will be sent out in early December. 

[tomarrymortbigbang]
