Looking for one-shot ideally on roll20
Hi - I'm a veteran D&D player/DM (started in 80s with red box etc) who now mainly plays Pathfinder and other weirder RPGs like Pendragon etc with my equally ancient mates. I mentioned that I played D&D to a friend who has an autistic son who has bought the 5e rules and wants to play (I'm friends with his parents through a wider friend group who met on holiday, so there are other kids I can potentially recruit), and they asked if I could DM something online.
I think there's a fair chance the kids'll just goof around, so I don't wanna hand-make something lovingly only for it to go tits up. What decent 5e one-shots are there on Roll20 where everything is done for you? Nothing cutesy or involving excessive amounts of fey or tieflings please.
Any help gratefully received!
