Campaigns
Run the game in the world you built.
The same world, the same lore, the same calendar — pointed at a table instead of a manuscript.
Plan the session
Lay out scenes, note what each one is for, and sketch how the table might get from one to the next. Keep the cast of characters your players will meet in one place, with the lines you want to remember to say.
Print what you need
Build a PDF of exactly the parts you want to have in front of you and leave the rest on the screen.
It is the same world
Your campaign is not a separate silo. It draws on the lore, the map, and the calendar you already built, so a session that changes the world changes the world.
