Scions of the Great Clans All Kindred froom neonates to elders accept the primogen as the voices of their clans in a prince's domain. What truly falls under those auspices, however, varies from city to city. From councils of primogen that pull a puppet prince's strings to the coteries of primogen that exist at a prince's whim, the only constant in a primogen's unlife is that politics align against her.
Counsel of Primogen includes:
Character and storytelling support for key figures in the Camarilla hierarchy New powers and political gambits used by the pillars of the Ivory Tower History, anecdotes, tactics and schemes employed by the primogen - and ways to confound them
I don't think the writing of Counsel of Primogen (a pun title?) deserves one star necessarily, but this is the first one of these splatbooks where I came away from it with nothing.
The Primogen are the council of the first in their Clans in a city, at least theoretically. But I don't think we need 120 pages to explain that sometimes it's not a simple one Clan, one Primogen system, that sometimes groups like the Giovanni or the Assamites get a Primogen seat, or that in some cities one Clan might have multiple seats. Sometimes the Prince is stronger, and sometimes the Primogen are stronger. Sometimes there are formal votes, and sometimes the council are simply advisors to the Prince. The Primogen spend a lot of time trading favors with people.
I don't have much more to say because there's not that much more to this book that wasn't already in other books. I can't see this being particularly useful even for people who plan to run a game where all the PCs form the council.
