Is there any info on how to change one's allegiance from one nation to another?

Unfortunately (for me, anyway), when I went through the cavernous maw in Batallia, I was sent to Rolanberry and I just assumed that I should do what those npcs said and headed to CN. Long story short, I made it all the way to to Windy and did the first mission and am now allied with Windurst with the Cobras. And while Cobra is a cool name or w/e, I'd rather be allied with my home nation of San d'Oria. =/
