This story is a sequel to New Friends Between Realities
In Equestria, while not much is known of dragons, one bit of lore is widely known among scholars.
The Orbs of Dragonkind. Within each lies the power to control dragons. When the five are brought together, it is said it will give birth to a power Equus has never known.
Nopony knows if there's any truth to the legend. Even among dragons, the Orbs are nothing but a myth.
But myths always have a grain of truth to them. And five ponies are about to discover a destiny none of them knew they had and a bond they have been waiting for all their lives.
