Siberys Dragonshard
Dragonshard from the progenitor dragon Siberys, they fall from the Ring of Siberys, the ring of crystals that encircles the world. While rare in Khorvaire, there are significant Siberys dragonshard fields in the continent of Xen'drik, and this is a potential source of great wealth for explorers. Siberys dragonshards are amber in color, with swirling golden veins gleaming within. These dragonshards are used in the crafting of magic items that require dragonmarks for attunement. Larger ones may be required for eldritch machines or the creation of legendary items or artifacts.
