Bio Snippet for later refining:
Growing up in the lavish clan of The Radiant Court, Sinistar gained a healthy curiosity, jotting down anything and everything he learned into journals and books. Even ones that already had words in them and maybe wasn't suppose to have in the first place...
His father, Andros, couldn't help but remark on how the behavior reminded him much of his own parents. After telling little Sinistar all about his wise Arcane scholar grandfather and failed-emperor gone entertainer grandmother, he was set to venture out and meet them himself!

Now Sinistar has found a home that suits him to a T. The Radiant Court was great, don't get him wrong. And he still very much loves his parents and other siblings. But here in Revery not only has he gotten along well with his Grandparents, but now he has a fatherly guardian angel AND a best friend who's a living fossil. He'll become older than the deities before he's able to fully study all these strange dragons in Revery!

He's extremely intelligent but has the carelessness of his grandmother. Even having the purity of a Priestess for a mother can't save you from genetic stupidity recklessness.

Nutmeg and Ophanim just need to get some baby monitors for this boy...
