Lore: Presenting
Presenting occurs when children "come of age", and usually happens during mid-late puberty, anywhere from ages 12-15.
During this time their dynamic characteristics begin to show, and they finish their physical development, just like humans.
The child's scent and sense of smell are the most important changes during this period. As physical changes will take longer to complete as their body matures. Their sense of emotionality will also change and can cause changes in their mental health or personality. Nonsexual dynamic-based urges such as nesting or scenting personal property also solidify.
It takes about a month, a full lunar cycle, for a child to complete the presentation process. During this time, parents may choose to keep their child home from school to stop them from getting overwhelmed in their "new" body.
Unlike humans, going through this change is cause for celebration. The Mutantur pars lunae, or Changing Moon Party is thrown by parents/families where they show off their child who is now considered a young adult, and announce their dynamic. For reference, it can be compared to a Bar/Bat Mitzvah crossed with a Sweet Sixteen or Quinceanera but is not attached to any specific birthday.
Like the name suggests, a Muntantur Pars Lunae is thrown the day after the second full moon of a child's presentation. If a child happens to begin presenting on the day of the full moon, the party can be held back for a cycle.
In terms of timing and scale, planning for this party begins shortly after a child hits puberty so that when the presenting phase begins the arraignments have basically all been made for the party. At the very least, families have a month to prepair.
The lavishness of the celebration depends on the family. Poor families often don't have the money for large gatherings and gifts, but it is customary to still celebrate in small ways. Often, the pack will throw something together for their child, as it is an important milestone in any cub's life. Middle and upper-class families may have a party that includes people from outside the pack/their immediate family. This is a significantly larger party that may last a few days.
Royal families view the "Muntantur" as a grand event and may last a full lunar cycle. Their kingdoms will often be included in the festivities, and like human royal children, the public often speculates on which dynamic they will be years before it happens. During a royal Muntantur, it is customary for other royal families, nobles, etc.. to approach the King or Queen with a letter of intention, detailing their desire to bond packs through marriage (using their child or young pack member and the newly presented royal cub). This begins the child's "debutante" period where they will be expected to be in public more often and show off their talents/personality.
*Twins, triplets, etc.. normally present in the same lunar cycle and so they have combined Muntanturs. While identical twins have the highest probability of all multiples of having the same dynamic, this is still very improbable.
