Bones taken from a dragon raised to life through terrible ritual
And their magicians made a terrible magic to guard the city; for by their necromantic arts they re-created the dragons which had once dwelt in this lost land, and whose monstrous bones they found in the forest. Those bones they clothed in flesh and life, and the living beasts walked the earth as they walked it when time was young.

Through the long passage of eons, rumors of dragons have always been passed down from generation to generation, and the legacy of these fearsome creatures grows with each telling.
The sad reality of dragons was that they could not fly, they did not breathe fire or acid, and they were not particularly intelligent. They were simply gigantic predators that lived centuries ago.
Through their arts, the Giant-kings resurrected dragons from the bones that they could find. They kept them as pets and bred them for battle in their gladiatorial games.
Their bones are particularly strong and can be worked into powerful weapons.
Recipe to craft Dragonbone equipment can be found in The Arena by learning from the totem (you need to have Star Metal Tools unlocked before you can interact with the totem).
