The Ythrian Old Faith involves animal sacrifices. On Earth, Jewish priests sacrificed animals whereas Christianity sacramentalizes sacrifice with bread and wine. The Ythrian New Faith is not sacrificial although it conceptualizes God as the Hunter.
An Ythrian has a bracing bone called the "alatan" but I am not clear where this word comes from. Also, how did territorial families of hunting carnivores become intelligent and then form a society larger than the single household?
