Note: I will be adding blurbs to most of these to summarize basic information as to their relationship with us or our enemies as appropriate and over time. @Duesal offered to help me track down some of this stuff, but as a note I'm just starting with the Stormlands because it was relevant. Any alterations to these statuses will be updated as the situation changes.
