Breeding Season.
Starting at 22 months old, wolves reach sexual maturity and are now considered as young adults (they are also mentally ~20 years old by human standards). This is when the "magic" and character development gets interesting as your maturing character might start to realize what they want in life (to gain a mate, to have a family, to start a pack, etc.) and figure out ways how to make it happen. On Ruins of Wildwood, there is one breeding season that any wolf 22 months or older can participate in. This takes place during the month of March. Eligible wolves may complete a breeding thread (that fades to black per site rules) during this time in order to produce a pup on-site. This is special, because the only pups permitted to join the game are those that are born on-site.
This article covers how to navigate the process of producing, creating and adopting out a litter.
