The Ageless are going to change humanity in a way that no other change ever has.  It will take hundreds, maybe thousands, of years before it is truly noticeable of course.  In the history of mankind, the elders have always died, leaving a new generation to continue on with only their ancestors’ writings or stories to say what they thought.  Now, one need simply walk up and ask an elder, and in the future the Ageless will be the oldest of all.
