Actually, almost all of the Amarr characters I know have thier own micro-loyalties, but IC they are good at hiding them. I've only been able to discover them through OOC convos, since IC there hasn't been much reason to express such loyalties until now.
Aldrith served Kador vassals and likes the Kor-Azor families, while he rather dislikes the Tash-Murkon and Sarum. Mitara, meanwhile, favors Sarum and Ardishapur. However they don't talk about politics, since it hasn't really mattered until now, but there is going to be a HUGE problem between them if the proverbial poo hits the fan.
