Well, they might be the Sun and Moon's children but they are groups of deities related to specific things, like Heaven, Hell, etcetera, or nations.

Nah they wouldn't be the children of the Sun and Moon- what about The Star and Sky though? That might work. Basically as it's important to your story- we need to know how they fit into the world. Thus far we have The Heavens- which no one has said what they do and are like yet. The Earth which are controlled by Jack Frost and his lot. And The Underworld. Kingdom of Brontes, home of all Monsters. So yeah, where do they fit in exactly?
