Diamantine
Diamantine is one of the Six Sacred Swords. While being owned by the Edrian royal family, it was a prize for anyone beating its wielder in the Tournament of the Sacred Sword.
It was split into multiple fragments.[1] Some of these fragments were embedded into one of the wrists of crown princess Edria Song and royal executioner Hannah Meiyer. Additionally, the Green Guardian is the humanoid form of another one of the fragments of Diamantine. These fragments can form whole weapons, looking like Diamantine.
At the end of Soulbrand, the emperor re-joins some of the fragments forcefully while being possessed by Akadi. After defeating him, Keras Selyrian gives the reunited Diamantine to the Green Guardian.
