Oh, wow, it's been a long time. I merged some DnD templates in Obsidian, modified them, then added Let's Talk and Keeping Contacts social systems (they're free and can be found on Dr. Gerald Ravenpie's site) and generated list of random events and NPCs to roll and choose from (you can come up with a list yourself or ask AI to give you some draft ideas). I also added in-game calendar and attached every event to a particular timeframe (like, this event will take 5 days to be completed, that will take 2 days, etc.).
