The Shards of the Pattern

Broken pieces of the First Map—each a spine of the Pattern and an anchor of reality. They hum with forgotten power and remember each other when brought near. Eidon says there are 'eight, or thirteen, or one shattered eight ways.' They are not just anchors but keys to something locked. Three have been found: in the Bell Tree (Drelmere), in the Underwater Well (Virelay), and in the Black Tower.
