One question though, are Luria Nova and Pian going to war each other like Giask and Pian..?
Probably not. The secession was part of a plan to remove Alanna without having to fight a bloody rebellion in Askileon and get a new name as some thought that the very name of Pian en Luries was a problem. The powers more or less in control of both realms are working together, at least for the time being. I don't foresee them fighting, but stranger things in the game have happened.
