yes, my point was more that I do not need a high level description of an entire continent to start a campaign, and I do not need it in a tutorial of how to build the setting for one either. If I know how to sketch out one region, the activity for the next one will not be all that different.
Depending on the campaign you might want that (DL, spanning most of Ansalon, so you need some high level idea of what is where from the start), you gradually expand along with the campaign, or you can ignore 90+% of the continent (Shattered Obelisk).
