Young dragons are relatively defenseless. They are born with relatively soft scales, which are shed and replaced with harder ones as the hatchling matures. Once a hatchling’s wings grow in, it marks the beginning of maturation. At this point they are often capable of hunting on their own and are usually left alone by their mother.
Vega stumbled upon Vi's secret for eternal youth shortly after her wings grew in. After spending her early years immensely jealous of the little Purple hatchling, this Ridgewing hatchie used her newly acquired "girly" charms to get Peble to share his youth spell. Vain and focused on her status within the group, she hopes to become a new leader among the eternal hatchlings just to show Vi that she has more friends and is better liked.
