I was arguing the clan leaders would have stayed on Kilrah to be closer to the center of power. I had forgotten the information from Action Stations.
[oddball theory]I've always had the impression of the Empire as being very focused on Kilrah, that's why the detsruction of the planet crippled them. I was picturing a scenario where each Clan Leader had a palace on Kilrah and nominal control of a portion of the planet (I think I was influenced by Asimov's Terminus.) Anyhow the sons of the Clan leader woul do their time out in the hinterlands (maybe govenor of a planet, or sector, getting to know what the clan held) but the eldest would eventually return to Kilrah to take over when his father died, stepped down, whatever. This idea also was influenced by End Run and Fleet Action in which it seemed the heads of the clans were always around when the Emperor wanted a meeting. Of course at those times, there was a crisis, so maybe that accounted for their presence. [/oddball theory]
Waiting for the servers I'm experimenting with to reboot so I hopped on for a couple minutes.
