The Map screen gives you a visual representation of your campaign setting. It helps the GM have a quick view of the realms and counties, but also the assets, spotting quickly where there is space for growth.
If you created your campaign using an existing template, a map of the world should already be available. If you created your campaign with the intention to create your own setting, the map you uploaded should be visible.
You can zoom in and out using the mouse wheel or the + and – buttons in the top left corner of the screen.
You can move the map in all directions using drag & drop. Simply left click anywhere on the map and hold, moving the mouse in the desired direction.
The map is accessible to both the GM and the Players.
