I think thats a great idea for the game. There should be a newbie cabal, complete with an immortal. The Adventurers circle or something. You should not even be eligible to join unless you select yes when it asks if you are a new player on char creation. Since those characters can't even turn brief off until level 30, most vets wouldn't bother joining. Maybe make the powers things useful to newbies, like improved outfitting or food scavenging and identifying skills, maybe use the recall skill past level 10 once an hour or something.

There would have to be a way to keep vets from rolling up in it to get pimped out gears and stuff. Maybe make them not be able to get edges or something.

It would do a good job of teaching people cabal politics and how to be in a cabal, and most people generally wouldn't mess with the members too much. (rest assured people would mess with you though)

Maybe members of this cabal are members from creation to deletion, and they get 5 deaths a con instead of 3 so they can die more and still rank and learn. Perhaps they have an item, so it could be taken, but dont make it related to any powers. That way they could learn to defend and retrieve, but there would be no consequences if they just got hemmed up by the vets trying, and it would return to them eventually.

I think its a dandy idea.
