My contribution to the 2018 run of the sshg_promptfest was Witches Love Poetry (PG-13; Severus/Hermione, others; 2027 words): Witches love poetry, but upon occasion, doggerel will do. (Cross-posted to my journal.)
I also posted a few undeveloped story ideas for the Prompt Fest which I turned into three drabbles and one ficlet:
A Sobering Moment (PG; Severus, Eileen; 100 words)
Closing Time (G; Hermione, Severus; 100 words)
Rude Company (G; Severus, an unexpected guest; 100 words)
Sleeping Bastard (PG; Severus, Hermione, original hag; 832 words): Hermione finds Severus having a bit of fairytale trouble.
