I have a few questions regarding the Greybeards. There probably aren't any real answers (otherwise I would probably have been able to find them) so I welcome any insight or thoughts you have on the topics.
1. How old are the Greybeards... I mean the individuals themselves and not the order. Obviously they are old but how old exactly? Are they only eighty or have they prolonged their lives and are maybe centuries?
2. How many Greybeards are there? Are there only the four or so that we see in-game or like many aspects of the games is it a scale issue and there are more members that we do not see.
3. Concerning tutelage and new disciples. How often do the Greybeards take students? One a decade? A year? A century? How many fail their learning?
