Belial

Belial is Grand Master of the Deathwing, the Dark Angel who wears bone-white Terminator plate and treats the Inner Circle's secrets as another kind of armour. Caliban is gone. The hunt is not. He leads the First Company into places Azrael would rather not put a name to.

Fallen, daemons, and anyone else who has seen too much of the Chapter's history tend to meet him in a room with no windows. He has held the Rock's most thankless command without turning it into a sermon, which is rarer among Dark Angels than the bone paint suggests.

Deathwing does not mean mercy. Under Belial it means the door is already shut.
