Wolves realistically live between 5-7 years in the wild. with that being said, a wolf in his prime will probably be about 3-4 years old, after that they are considered an elder.
Pups: Pups are small for only a brief amount of time. By six months they are already quite large. That being said, a week could easily represent a month in this rp, aging wise for pups. Meaning, by 6 weeks, your pup should be half the size of an adult, after 12 weeks, they should be the max size they will grow.
Adults: Adults will stay in their prime for a lengthy amount of time. Members of The Divine can become elders only after at least 9-12 months of using their character.
NOTE: Age shall progress whether you are active or not. The storyline will continue forward and all characters will be affected by time and/or story effects whether the user is present for them or not.
