Thats an interesting allowance, one might even say ‘loop hole’ to a way of fitting more story in to the word count allowed. Not having to explain character’s motivations for example, as they are already familiar to some members. I’m guessing the same is allowed for the 75 as I’ve always enjoy
@Luiglin Dark Lord stuff (RIP or will he do a Superman) for that reason, but if I’m honest, I wouldn’t vote for those stories for the same reason. Unless of course one unquestionably deserved it.
I did the Dark Lord stuff more for my own amusement than to garner votes. Remember, I did do a whole year of Dark Lord 75s, whatever the genre or theme... and yes, I still class the Dark Lord as the cause of the cataclysmic event that wiped out the Dinosaurs as being historical fiction.
However, I do understand that by doing so I did take huge liberties. Other 75s are standalone stories and I tried to make sure that the Dark Lord tales did the same. They did stretch the point though by having a consistent cast. I'm also aware that they were very much marmite tales.
As I said though, they were primarily to help me flesh him out (just over 50k into a novel with him now and other two WiPs from other characters in the same world at 40k and 25k).
If they made people smile then great, that was the bonus for me and not a tick on a radio button

(not saying that I didn't appreciate any ticks folks, all egos like to be stroked).
So, my advice
@JS Wiig is to give it a try but not as a direct sequel(s) and don't expect votes. Then again, you're probably a way better writer than me and may well manage to pull it off
EDIT: and yes, the Dark Lord will not be seen on the Chrons again. So all can breathe a sigh of relief. That is unless either this site or I'm still here in 200-300 years time when the stars are aligned, a ring is found or some other fantasy trope occurs and he gets resurrected.
