Fir Clan. (Story.)

The one who leads the clan, keeps the clan in order, protector, and primary negotiator of deals with the Other Clan... And as of (semi) recently, The dog pack.
The next leader is chosen through the direct children of the current/previous leader. ( Or the chosen deputy if the line dies out. )

Those of medical talents, Often chosen from the grand starry cat above, leaving signs for whom should be the next healer, or if you are lucky told from the cat themselves!... Even... if they have not been in contact for a long while... its an important role.

 Direct offspring of the leader will continue to be leader, however the leader may pick another deputy alongside to lessen the load of work. ( Plus if the leaders line dies out the stand in deputies line will become the one in charge! )

The hunters , fighters and den builders of the clan. A vital role in any clan. These cats are paired up with another or maybe three in some cases to be able to travel safely across the large territory. Lest the dog pack next to them attacks, at least someone can report the reason for a missing cat...
