Can your Fanfic of Doom/Snape fic can be found somewhere in the depths of internet?
Hello! Thank you for your interest 😄.
I do have some short Snape fics floating in the depths of internet, yes. Most of them date back to 2005 (!), so - I'm hesitant to link to them because I'm that much older now and have come to find them a bit cringeworthy in the meantime 😅.
The Fic of Doom is not one of them, though. I have several, very fragmentary, prose bits sitting on my computer, but they predate Deathly Hallows. Any post-Deathly Hallows bits are all in the form of snippets, drawings and bits of comic and most of it has been posted on this tumblr.
I still toy with the material of the Fic of Doom, hoping to decline it into smaller stories that I could feasibly draw and use to present the bits that are dearest to me. It's difficult because my medium of choice nowadays is comics, and they are awfully labour-intensive for me. What time I have is normally spent on my Gawain comic, which I actually own and could publish if I want.
I still do a Snape Stint every year though.
My annual Snape Cycle is roughly from October to December, when I draw contributions for Snapecase and HoggywartyXmas (both on Livejournal). In January, after the reveals, I post them here. Snapecase has age prompts and Hoggywarty is a kind of Secret Santa fest where I'm supposed to answer to prompts, and I'm not free in my choice of characters. So far, I've never managed to shoehorn the Fic of Doom materials in... I guess that I'm also concerned that people don't much like receiving gifts with someone else's OC in them, especially not when the OC ends up marrying Snape 😅. I don't know if the perception has changed, but back when I wrote fic in Days of Old, pairing Snape with an OC was a Grave Sin. So Doom!Snape and his post-Deathly Hallows family of an OC wife and four (!) kids basically only live in my notebooks. I may feel a burning need some day to share more of them, seeing as I spend a lot of time thinking about them.
