What Just In Time Worldbuilding makes

Topics fantasy, worldbuilding, writing, history, roleplaying

Welcome to Just in Time World Building! I build fantasy worlds by drawing on real world history and knowledge. I share that random historical and sometimes science knowledge with you and I also suggest how you can use that knowledge in a fantasy context. New videos every Tuesday, and some every Saturday, either a short or a livestream or a World Building Blueprint podcast. I have been a role-player and games master for twenty years and am in the middle of writing an epic fantasy series, Sangwheel Chronicles! Join me in building new worlds to explore. Books by Marie M.
