Campaign planning/world building
(ttrpg.network)
A place where Game Masters, Dungeon Masters, Storytellers, Narrators, Referees (and etc) can gather and ask questions. Uncertain of where to take the story? Want to spice up your big baddie? Encounters? That player? Ask away!
And if you have questions about becoming a Game Master you are most welcome with those as well!
Rules
Highly recommend looking up slyflourish and the series "lazy dungeon master". Helped me streamline prep a lot. Biggest things was coming up with the few things you want feature, understanding a general sequence of events and then tying them together along the way.
No session will survive contact with the party, and neither will a campaign. Being able to keep a loose framework you can work within throughout the campaign is the way everyone at the table can have fun.
