"Dhianeila calls Bellcross and his brothers and sisters the Heroic Tribe. They were reeeeally big and strong, but they almost destroyed everything because they didn't have hearts. Age's dads took them and put them inside Age and the other Nodos to teach them how to have hearts and to help us fight."

It was...about as confusing an explanation as any someone like Age would give.
