Siberys

Siberys is the dragon of magic and celestial power, shattered in the battle with Khyber. His remnants form the Ring of Siberys, a glowing band of crystals orbiting the planet. Siberys dragonshards fall from this ring and are the rarest and most potent. They are closely tied to dragonmarks, enhancing their power and enabling complex magical rituals. Siberys represents order, arcane mastery, and the divine.
