I had a thought today, relating to minor Amarr nobles.
In some missions, like the epic arc, it is mentioned that very minor Holders do not have any land, and may only have a space installation.
Which means that a feudal superior, such as one of the Heir Family members, would be able to create several subservient minor holders, granting them the right to put up a space installation in a system.
Which then is a means of control, as those space installations would tend to sprout radio telescopes and other spying type equipment, as the minor Holders would then inevitably start spying on each other and any Planetary holders in the system.
So, when a planetary holder starts rocking the boat, they might soon find themselves being spied on by several dozen minor Holders eager to replace them.
Spies, spies everywhere. I think this would have quite an effect on anything going on in Amarrian space. Someone, somewhere would have Seen Things.
