Pack (canine)
Animals which typically predominate over others are associated with the term "alpha". Among pack-living wolves, alpha wolves are the genetic parents of most cubs in the pack. Such access to mating females creates strong selective pressure for intra-sex competition.
Masquerade society
Every Pack has a Ductus (a vampire of higher status and experience who functions as leader) and most have a Priest. Priests lead or oversee the rituals of a Pack. There are some universal rituals within the Sabbat, but Packs usually develop their own, with a wide variety of uses.
