Zahariel El'Zurias

Zahariel El'Zurias was a Calibanite Dark Angel Librarian, cousin to Nemiel, who stayed with Luther when the Lion took the war off-world. The forests had already shown him the Ouroboros. Loyalty to Caliban became a different religion than loyalty to the First Legion, and he was young enough to walk into it.

He killed the then Lord Cypher and took that title from Luther's hand. Whether the Cypher still walking in M41 is Zahariel in another century's armour is a question the sources refuse to close. Nemiel died arguing the other side of the same family.

Caliban is a grave with a name. Zahariel is one of the voices that grave still uses.
