What if the tribes age differently? Here’s my two cents:
MudWings start to grow the fastest physically, but mentally, they stay kids the longest, not being fully able to speak until about two. They become adults at about eight or nine.
SeaWings are one of the smaller tribes and stop growing at around six or seven, but they are able to speak aquatic from about three months and are basically fluent in dragon at age one. They are adults, mentally, at age seven.
RainWings are highly intelligent, able to speak at only a few months and mature at about age five. This is because the rainforest is dangerous, so it’s best to be cautious and calm, something that young dragonets can’t really do.
NightWings grow slowly, but continue to grow steadily after their slowdown point, which is about eight. They are able to speak at around one year, and are adults at around nine, mentally.
SandWings grow very slowly, like Sunny, and are not physically mature until about ten. Mentally, they mature at about six.
IceWings learn to speak at about two, and grow swiftly, not quite as swiftly as MudWings though. They mature mentally at about eight.
SkyWings mature physically at around seven, same with mental maturing, and learn to speak at around one year.
I’ll do Pantalan tribes later
