Dragons are born in twins set, one dominant while the other is submissive. 
One can't survive without the other, the dominants are sent to military schools, they'll spend most of their life-controlling their Dragon side.
While the other half goes to Dragon Academy, they'll learn how to cope with being submissive, they are categorized into littles, pets, or simply submissive. 
The older dominant would meet them there, teach them how to shift, protect them from all dangers, and finally claim them as theirs forever. 
Kaiden is a special case, a little who never regressed before, she also never cried, until crossing roads with Adrian, a fiery red dragon.

Dragon Academy

Mama's parents are scary, they look like her, but they are scary, even River is acting shy and River is never shy! Not even when we bath together, he'll just walk around naked until mama yells at him and make him dress up. For now we are both hiding in her arms, scared of her parents, feeling all shy, they were talking in another language, Russian, it's mama's language.

River said hi first, I needed a lot more encouragement to do so, in the end, I did say hi, they both cooed at us, it was all cute and sweet, until they turned to more personal questions, questions about us.

/"How come your other little...is...he's.../" the first woman says with a thick action turning to her partner for help.

/"Too little/" she adds, should I feel offended, so what if I'm younger than River.

/"Chase little age is younger than four, but River is eight/" mama says all proud of us, making me smile, I love making mama proud.
