Thanks for answering though. I just didn't know who owned that bit before all the infestations and such; figured it was still part of Lordaeron because of the big wall surrounding Gilneas. http://bit.ly/flrWZ5

You may be confused by how the in game map shows Silverpine. Technically there should be a line right around the middle that says "everything north of this= Lorderaon, everything south of this=Gilneas." Those Gilnean areas belonged to the Crowleys.

Nations don't really mix with feudalism very well. Nations involve loyalty to an abstraction; it's possible for a nationalist to be loyal to his nation and yet disloyal to those who rule. Feudalism is all about people; the Kingdom of Bob is everywhere the people sworn to King Bob happen to live, and any subject disloyal to King Bob is necessarily a traitor to the kingdom... no matter how stupid Bob's policies are.
