A nameless dragon was born from tons of corpses of their kind or the revenant who used to live once. By ancient no one knows about a dragon king where it is, where it was born but he fractured his powers surrounded with magic and emanated it around the world. Who’s dominate the power, they’re called The Greatest. Whoever was born to the greatest is in the egg. The egg is powerful and strong, that’s why they are rejected from the pack though some of them lived together, they will stay alone.
Their appearances are imprecisely but they’ve snake tails, big jaws like a wolf and long fangs. Also the body is mixed by life in the region. About the powers they use by any elementals from fracture or their own instinct. Many hunters and mercenary wants to kill them for horns to make medicine, eyes for see the truth and fangs or jaws for a weapon, if someone can usurp their hearts and eat the fracture, old greatest will die and the new will replace so they know how to live, how to hide a real from.
Now it’s only 10 the greatest in the world. No clues, no news, maybe they’re walking around you somewhere.
