I need to take a moment to rave about my absolute favourite tool for writing right now! WorldAnvil.com! Its a brand new project that is already amazing. and free to use. You can make maps and drop location pins. Create timelines. Write articles using helpful templates. Engage with a really cool worldbuilding community on their discord server. Follow other worlds. And much more … . It’s being made by a two person team and already its extraordinary.
If you write, RPG or just like to worldbuild, please give WorldAnvil.com a try!
