About the age thing, I think it may be a conflation of two things: born werewolves could potentially follow the Coligny Calender, and well, they age a bit slower.
-The calender synchronized the solar year and lunar month.
-Probably started in Summer or Autumn
-355 days and an extra (13th) month every 2.5 years.
-Months divided into fortnights (of 15 + 15, or 14)
-30 day months were lucky, 29 day months were unlucky
-New or Full moon is the start of the Month (maybe)
-Math stuff in the last bullet that amounts to what I think is the following: they follow a system with the 13th month that catches up to our system of 12 after about 30 years.
-Stealing this quote from wiki because.. well you'll see:
"The mistletoe, however, is but rarely found upon the robur*; and when found, is gathered with rites replete with religious awe. This is done more particularly on the sixth day of the moon, the day which is the beginning of their months and years, as also of their ages, which, with them, are but thirty years. This day they select because the moon, though not yet in the middle of her course, has already considerable power and influence; and they call her by a name which signifies, in their language, the all-healing."
-Aedrini(os) - Bright (or Hot) Month"; cf. Old Irish aed "fire", "heat" Aka, the same root as Aidan
If I see anything else I'll definitely send you the info, also, Yay! I was so right about Marco and Deuc.
Oh, this is cool. I'm definitely going to look into this more!!
