World building

Note: Please do not overlook the other new post about scheduling.

Allright, fellas, tonight a new locale was introduced: The country (or whatever it is) of Gottland. How much do we want to flesh it out initially? I know we're all pretty well-versed at making things up as we go, but having some framework sometimes allows for more robust improvisation later. Are there any notable figures we should burn up? Perhaps the man who is the most vocally opposed to the armed resistance against Mercia? Should we more clearly define the relationship Gottland has and once had with both Mercia and Umbria? I'm interested in knowing a little more about Gottland's reputation as a country and as a group of people; does anyone have any strong initial impressions?
