Adriel, the Creator
The first seven Judges inherited their power and titles. Only Ozriel and Adriel are the exceptions: Ozriel because there has never been a Reaper before him, and Adriel because there has never been a Creator since.
Adriel is a myth to the modern Abidan. Some of their oldest records posit his existence, but he vanished before the Eledari Pact was signed. The strongest pieces of evidence for his existence are indirect references left behind by the first Abidan Court.
The Judges can defend, maintain, and alter Iterations. They can combine fragments into new worlds.
But only one person could, according to legend, design and create Iterations out of whole cloth: Adriel. He created new worlds, introducing fresh pieces into the cycle of existence.
His weapon, the Hammer of Adriel, is sometimes used by the Abidan as a symbol of creation.
