Still not sure. I have allot of stuff to do still. Do you have any suggestions. I don't want anything modern in feel.

Not the world itself but the pasts of your kingdoms can be group endevors. Examples such as past trades, religion from one being practiced hrought another, military conquests? Refugees from others conflicts. 
Its to start off with interactions, so we aren't lost on what needs to be sorted when it starts.
