I've never really seen political power struggles in wartime, while I've seen them in Luria as well as in Cathay and Toupellon, all in peacetime.
I find that a lot of roleplay oriented things sometimes fall to the wayside during war, especially on islands not called Dwilight. Realms lock in to very team-oriented play where it is all about doing what is necessary to beat the other team. Things like religion, the ideas of feudal hierarchy, and other roleplay necessary parts of the game often fall to the wayside when the the main concern for everyone is "how much CS are the enemy rallying? Where at? Ok everyone refit and rally to X! How many cavalry do they have? Archers? Okay attack! Nice fight everyone, lets refit quick!"
Most other things get ignored. At least, in my experience.
