I've never liked the 'Bearclaw McSuperawesome was the oldest living Wolfrider ever'-notion. It just seemed to be way to make him awesome. (reason for the nickname). I don't hold much stock in group who are genetically coded to 'forget' stuff to better survive.
I seem to remember reading Valloa lived from before Timmorn became chief to Freefoot's time.
Icetooth must have ancient.
Longreach/longbranch: Looks like the same damn person if you ask me.
It only makes SENSE some of the other chiefs were older then Bearclaw.
I couldn't make the reigns add up if I had to stick to the fact Bearclaw is supposed to be the oldest ever.
