Nightmare of Val Sinu, Hellbringer
From Destinypedia, the Destiny wiki
The Nightmare of Val Sinu, Hellbringer is a minor Nightmare seen in the Hall of Wisdom as an Assassination target for the Patrol found in Archer's Line. Once a feared Hidden Swarm Wizard, it has slain a few Guardians before her death (possibly during The Great Disaster). Now recreated by the Pyramid as a Nightmare, it continues to haunt the Phantom of one of her slain Guardians, where she would be killed by a patrolling Guardian, and the Phantom put to rest.
