There has been some discussion of how Holders should act, and whether actual Holders would have time to be a capsuleer, or would be busy with their Holding.
This leaves 2 of the Amarr ancestry options in a bit of a pickle - "Liberal Holder" and "Religious Reclaimer" are frequently interpreted by players as having an actual Holding Title, the alternate interpretation is that the player character is a sibling or non-first child of the actual Holder, and is out of the line of succession, and thus has literally nothing better to do than to be a capsuleer and quest for Glory and so on, much like in how many tales of knights, the knight is a 3rd or 4th son, and thus has few duties assigned to them, and have the free time to go to tournaments, fight dragons and other such things.
There is also discussion about how a member of an actual feudal nobility would act. Unlike most contemporary nobility, Amarr nobles play an active part in the governance of the Empire.
When thinking of things to write about for my stories, and family background for my characters, a good source of inspiration that I found, was a collection of tales of how several local noble families acted in past centuries, in times when the nobility was an active part of the governance of the country.
These tales can be read at:
