With garou/fera, homid-born tend to have their First Change during adolescence or just after and the animal-born tend to have it as an adult.
So obviously, homid-born would appear the age they are and the animal-born would look like an adult when able to shift into a homid form: because that's what they are.
But, out of curiosity, with those who are metis: how old would they actually look with their homid form, after undergoing their First Change?
To use the garou as an example: this apparently happens when they are about 8.
Is there any official information on what the human equivalent of this age would be? As in the range of teen -> adult?
I have been able to find that metis certainly are children for a good while, full childhood periods being mentioned, but no more than that about their pre-change aging rates.
