Adonalsium

Adonalsium is the force or being where all Investiture comes from in the Cosmere. Adonalsium is usually referred to as the God of the cosmere. It was shattered into a series of 16 Shards, each of which is a particular aspect of Adonalsium. This happened in an event now known as the Shattering, a group of individuals opposed and killed Adonalsium. Hoid is often thought of as a shard, despite him repeatedly telling people that he's not. The events on Yolen regarding the Shattering will be addressed further more in Dragonsteel.
