Mengoor

"Let one of you be the learner. Learn the shape and the direction of strength. Tithe both sides of your blade to me."

- Oryx, the Taken King

Mengoor is a Hive Knight that appears as a boss in the Court of Oryx. They are accompanied by their comrade Cra'adug. Both Knights possess an invincible shield that is only nullified when they are in close proximity to each other.

Books of Sorrow
The Books of Sorrow briefly describe them as being partially responsible for the extermination of the Taishibethi species, standing upon the Raven Bridge and killing Taishibethi for a decade. At the Golden Amputation they were punished for tithing their kills to one another and not Oryx.
