>> I just thought a mixture of different kind of prompts to give as much choice as possible. If you have another idea I am open. <<

Multi-list fests have been very popular, with short lists of prompts based on subthemes. Looking at your base theme, possibilities include:

* Firsts (first episode / issue / book)
-- meet-cute
-- meet-ugly
-- first kiss
-- first fight
-- foreshadowing

* Particulars (things unique to a fandom or at least rare)
-- daemons
-- dragons / fire lizards
-- asexuality
-- sedoretu
-- troll romance

>>I was also thinking maybe a Drabble Fest. I'm not sure we've done that either. That might be better considering how busy November is and random prompts would work for it. Any thoughts? <<

Locking the whole fest to one form could discourage people who aren't into that. But a sublist designed for small fills would be fantastic. I just recommended this community to someone busy who was looking for easy fanac.
