"I'm the only one who inherited unusually young - late teens, early twenties is the normal age to pick up a primacy. Jerist lasted longer than most and Auney could have been prime for another fifty years if it weren't for the ill-fated flying experiments, Nerine and Valdin both should have had at least a couple more decades in them apiece but had to tear each other apart. Alser's largely a coincidence. We're clustering because the deaths clustered - my age is mostly happenstance as far as that goes."
