Nightmare of Talgoth, Soul Smasher
From Destinypedia, the Destiny wiki
The Nightmare of Talgoth, Soul Smasher is a minor Nightmare seen in The Gatehouse as an Assassination target for the patrol found in the Hellmouth. Once a widely feared Knight among the Hidden Swarm, it would slay a Guardian before his demise (possibly during The Great Disaster). Now resurrected as a Nightmare by the Pyramid, it continues to haunt the Phantom of his slain Guardian. However, he would, instead, be killed by a patrolling Guardian after following up on the Phantom's request.
