Unfortunately as Arkon has left Eve rp this list is also not going to be updated.
As a general rule of thumb from a practical rp point of view, being a holder of more than a Planet (e.g. a system) has caused issues with players claiming mary-sueing (and even being a planet can be an issue depending on whether Lore has spoken as to who a holder is). The safest courses can be to say one is a holder of a holding within a larger npc holding (such and a such a planet, etc.) which I see many amarr side rpers do or being non specific as Esna is (but that's no fun!)
