Nightmare Servant of Ir Yût
From Destinypedia, the Destiny wiki
The Nightmare Servant of Ir Yût is a Nightmare of a massive Knight seen in The Summoning Pits during the Faculties of the Skull Quest, where the Knight, who once served Ir Yût, the Deathsinger, was being used as an amplifier for a Hive communion where a Wizard Devoted of Ir Yût sought to become a Deathsinger. However, The Guardian, seeking to create a powerful weapon, would interrupt the ritual, killing the Devoted and vanquishing the Nightmare Knight.
