Something I'm still confused on: Are the Circle of Nine all of the original High Ones or were there others on the ship also? If there were, as I've seen some fans discuss, other High Ones, then why don't they get nifty titles too?
Haken himself mentioned Guin, Ima and Tislin as dead or gone. Almeck, Menolan, Seilein were in the palace too. They didnt have titles.
Have you read the story about the high ones in Botc the fifth book?
As the sunfolk all fit in the palace, I think the palace had a lot more high ones than just the nine who were piloting it.
I haven't read much of BoTC and only count the stuff that has been officially retconned as canon, since too many of them outright contradict canon.
