Would anyone mind giving me a brief rundown of the alliances and grudges of each realm?
I do know that Greater Xavax and Fallangard are federation parnters and Vix Tiramora are allied with Perdan, Caligus and Perleone.
Is Perleone a puppet realm of Perdan?
Hic Sunt Leones,
I can really only speak of the Southern Realms:
Alara, Minas Nova, and Perleone, are allies. They were the original three realms that arrayed themselves against Xavax when Xavax declared war against Alara. They've also recently (or were already) allied with Perdan and Vix. Minas Nova and Xavax hold a mutual Hatred, while Alara/Xavax Have Hatred/War repectively. Perleone/Xavax are merely at War standing.
Perdan and Vix are at war with Xavax and Fallangard. Their greatest achievement to date has been the taking of Abadan from Fallangard.
Caligus is allied with Alara and Perleone, but has been ignoring those alliances in part of an agreement between the High Queen and Xerarch that as long as Fallangard only engaged in defensive actions within Xavax, Caligus would stay out of it. Caligus has thus remained at peace with Xavax and Fallangard. Caligus' High Queen did give their ally Vix travel rights through their regions though (and let us know ahead of time that she was going to do it). It remains to be seen if any of these verbal agreements hold with the change in rulership in Caligus.
